    On the 2012-2015 Toyota Tacoma, certain later second-generation Tacomas were included in Toyota's large Denso low-pressure fuel pump recall. The impeller can deform, causing the pump to seize or lose output, which may lead to hard starting, rough running, stalling, or a complete no-start. Because the engine can stall while driving, this is a significant drivability and safety issue.

    Common Symptoms

    • extended cranking
    • no-start
    • engine stalls while driving
    • hesitation on acceleration
    • rough idle

    How to Fix

    Confirm recall eligibility by VIN first, since many trucks were repaired under Toyota's campaign. If symptoms persist or the truck is outside campaign coverage, fuel pressure testing and pump current checks can confirm a weak or failed in-tank pump. Replacement of the pump module or pump motor with the updated part is the standard repair.

    Owner tips & cautions

    • TipRun the VIN through Toyota's recall lookup before paying out of pocket, since many affected trucks qualify for free pump replacement.
    • TipIf the truck intermittently cranks but will not start, check actual fuel pressure before replacing ignition parts.
    Typical repair cost:$0 - $1,200

    On the 2000-2015 Toyota Tacoma, tacomas in this era commonly develop EVAP system leak faults that trigger a check engine light, often caused by a failing charcoal canister, stuck vent valve, cracked hoses, or a rusted filler neck in salt-belt trucks. Owners usually notice no drivability problem, but the truck will not pass emissions and the light often returns after a gas cap replacement. The pattern is well documented in NHTSA complaints, forum troubleshooting threads, and repair databases.

    Common Symptoms

    • check engine light on
    • emissions test failure
    • no noticeable drivability issue
    • fuel smell near rear of truck in some cases
    • code returns after replacing gas cap

    How to Fix

    Proper diagnosis requires smoke-testing the EVAP system rather than guessing, with close inspection of the gas cap seal, canister, vent valve, purge valve operation, hoses, and filler neck. Depending on the leak source, repairs range from replacing the cap or vent valve to replacing the charcoal canister assembly or corroded filler neck. Clearing codes without smoke-testing often leads to repeat repairs.

    On the 2005-2015 Toyota Tacoma, multiple 2nd-generation Tacoma owners report a brake pedal that slowly sinks to the floor or feels spongy even after bleeding, often traced to internal bypass failure in the brake master cylinder. Toyota issued service information for diagnosing low or sinking brake pedal concerns on Tacoma, and owner complaints describe reduced stopping confidence without obvious external fluid leaks. The problem can be intermittent at first, then worsen as the internal seals wear and fluid bypasses inside the cylinder.

    Common Symptoms

    • brake pedal slowly sinks while stopped
    • soft or spongy brake pedal
    • longer stopping distance
    • firm pedal returns temporarily after pumping
    • no visible brake fluid leak

    How to Fix

    Diagnosis usually starts by confirming no external leaks, checking rear brake adjustment and shoe condition on drum-equipped trucks, and isolating the master cylinder by holding steady pedal pressure. If the pedal slowly drops and the rest of the hydraulic system checks out, replacement of the master cylinder is the common repair; some trucks also need a brake booster inspection and full fluid flush. After repair, the system should be bled properly and road-tested to verify a firm pedal.

    On the 2005-2015 Toyota Tacoma 1GR-FE 4.0L V6, the cast-iron exhaust manifolds on the 4.0L 1GR-FE V6 are prone to cracking from repeated heat cycling, with thin webs near the firewall failing first. This is a distinct mechanical failure from the well-known injector 'Taco Tick' and the secondary-air-injection problem. A cracked manifold produces a loud ticking or tapping that is worst on a cold start and may quiet as the engine warms, often with a faint exhaust smell at the firewall. Beyond the noise, the upstream exhaust leak skews the air/fuel reading, ruins fuel economy, can trip lean/misfire and oxygen-sensor codes, can cause a smog-test failure, and over time can cook the catalytic converter and exhaust valves. Owners commonly find the driver-side (left bank) manifold cracked first because of its packaging near the firewall.

    Common Symptoms

    • Loud ticking or tapping noise worst on cold start
    • Noise partially quiets as engine warms up
    • Faint exhaust smell near firewall
    • Drop in fuel economy
    • Louder under light acceleration/load
    • Possible lean/oxygen-sensor or misfire codes
    • Smog/emissions test failure

    How to Fix

    Confirm the source with a cold-start listen and a smoke/soap test at the manifold-to-head flange and along the manifold casting (a cracked manifold gets louder under light load/acceleration, unlike the harmless injector tick). Replace the cracked manifold(s) with OEM or quality aftermarket units and new manifold gaskets and hardware; many shops replace both banks while access is open. Use new exhaust manifold-to-head nuts/studs and the OEM gasket to prevent a repeat leak. Replacing only the gasket will not cure an actual casting crack.

    On the 2005-2023 Toyota Tacoma, the thin sheet-metal heat shields over the exhaust manifolds and catalytic-converter/exhaust pipe crack around their spot-welds and mounting tabs from years of heat cycling, then buzz or rattle against the exhaust at idle and under light throttle. The noise is often mistaken for a more serious internal engine knock or a loose catalytic converter, but it is a harmless cosmetic-cover vibration. Toyota documented heat-shield rattle on earlier Tacomas via tech tips (adding mesh grommets/reinforcement), and the failure mode recurs across generations as shields age. It is distinct from an actual cracked exhaust manifold (which causes a true exhaust leak).

    Common Symptoms

    • Metallic buzz/rattle at idle or light throttle
    • Noise changes with RPM
    • Sounds like a loose internal part but no power loss
    • Reproducible by tapping the shield
    • Worse when cold, may quiet when warm

    How to Fix

    Confirm the source by lightly grabbing/wiggling the heat shield with the engine off (cold) — a loose shield will shift and the noise reproduces when tapped. Fixes include re-securing with a hose clamp or stainless screws/washers, welding the cracked tab, replacing the shield, or (last resort) removing it where legal and safe. OEM/tech-tip remedy on affected models added wire-mesh grommets and a reinforcement patch to damp the rattle.

    On the 2005-2023 Toyota Tacoma, p0011 on the Tacoma (4.0L 1GR-FE and 3.5L 2GR-FKS) means the Bank 1 intake camshaft is timed more advanced than the ECM commanded. On Toyota's VVT-i system this is overwhelmingly an oil-control-valve (camshaft timing OCV / VVT solenoid) problem, not a mechanical one: the solenoid sticks — usually from sludge, debris, or degraded oil clogging its filter screen — and fails to bleed off oil pressure, holding the cam advanced. Neglected oil-change intervals or low oil level are the classic trigger. It is distinct from P0016 (which is a mechanical crank/cam correlation mismatch) because P0011 is specifically a stuck/over-advanced VVT actuation caused by the control valve or oil.

    Common Symptoms

    • Check engine light on
    • Rough or unstable idle
    • Engine hesitation or occasional stall
    • Reduced fuel economy
    • Slight power loss

    How to Fix

    First check engine oil level and condition and change oil/filter with the correct viscosity — the cheapest fix and a frequent cure. If the code persists, remove the Bank 1 intake camshaft timing oil control valve (VVT solenoid), clean or replace it, and clean its filter screen; test the solenoid's resistance/operation. Clear codes and confirm the cam can return to the commanded position.

    On the 2005-2023 Toyota Tacoma 2.7L I4 2TR-FE, p0302 flags a detected misfire on cylinder 2. On the 2.7L 2TR-FE four-cylinder Tacoma this is a well-known pattern: the coil-on-plug (COP) ignition coil over cylinder 2 weakens or fails, producing a rough-running, single-cylinder misfire. Worn iridium spark plugs (overdue past their interval) are the second-most-common cause, and occasionally a fuel injector. Because each cylinder has its own coil, the fault is easy to isolate by swapping the coil to an adjacent cylinder and seeing whether the misfire follows. Chronic misfire can also set P0420/P0430 later by dumping raw fuel into the cats.

    Common Symptoms

    • Rough idle / engine shake
    • Flashing or steady check engine light
    • Hesitation or stumble under acceleration
    • Slight loss of power
    • Occasional gas smell from unburned fuel

    How to Fix

    Swap the cylinder 2 ignition coil with an adjacent cylinder and re-scan: if the misfire moves to that cylinder, replace the failed coil. Replace all spark plugs as a set if they are near/past the service interval, using OEM Denso/NGK plugs at the correct heat range. Inspect the coil boot and connector for cracks/corrosion; if coil and plug are good, test the cylinder 2 injector and check compression.

    On the 2000-2015 Toyota Tacoma, across both first- and second-generation Tacomas, owners commonly report coolant leaks from the radiator's plastic end tanks or the tank-to-core crimp seam as the radiator ages. The leak often starts as a pink crust or dampness near the upper tank, then progresses to visible dripping and overheating risk if ignored. This is a routine age-related Tacoma failure documented in owner forums, repair shops, and complaint databases.

    Common Symptoms

    • coolant smell from front of truck
    • pink or white crust on radiator tank seam
    • low coolant reservoir level
    • visible coolant drip under radiator
    • engine temperature rising at idle or in traffic

    How to Fix

    Inspect the radiator tanks and seams for dried Toyota pink coolant residue, pressure-test the cooling system, and verify hoses and cap condition before replacing parts. The standard repair is radiator replacement, often along with new upper/lower hoses, cap, and fresh coolant. If the truck has overheated, the thermostat should also be checked or replaced.

    On the 2005-2023 Toyota Tacoma, p0128 is one of the most common Tacoma codes and almost always means the engine thermostat is stuck open (or opening too early), so coolant reaches the radiator before the engine hits its target operating temperature within the expected time/airflow window. It is especially frequent on the 4.0L 1GR-FE and 2.7L 2TR-FE during cold weather and sustained highway driving, where cold airflow keeps the engine below the ~180°F (82°C) regulating temperature. The ECM watches coolant temp vs. expected warm-up and flags P0128. A brittle plastic thermostat housing on the 4.0L can also leak as it ages, sometimes accompanying the failure.

    Common Symptoms

    • Check engine light with P0128
    • Temperature gauge stays low or drops on the highway
    • Weak/cold cabin heat
    • Slightly reduced fuel economy
    • Longer time to warm up

    How to Fix

    Replace the thermostat, using a genuine Toyota (OEM) or Aisin unit — cheap aftermarket thermostats are a repeat-failure source on these trucks. Install with the jiggle valve oriented upward and use a new gasket/O-ring; refill and bleed the cooling system. Verify the engine reaches full temp and the code does not return. Inspect the thermostat housing for cracks/leaks on the 4.0L while the job is open.

    High ConfidenceVerifiedReviewed Jul 2026

    On the 2005-2023 Toyota Tacoma, on the Tacoma's V6 engines (4.0L 1GR-FE in 2005-2015 2nd gen, 3.5L 2GR-FKS in 2016+ 3rd gen), Bank 2 is the driver's-side head (cylinders 2-4-6). P0430 sets when the rear (downstream) oxygen sensor voltage begins mirroring the front sensor, meaning the Bank 2 three-way catalytic converter has lost oxygen-storage capacity. On high-mileage Tacomas (typically 120k+ miles) this is usually genuine converter aging, but a very large share of Tacoma P0430s are actually a lazy/worn Bank 2 downstream O2 sensor or an unresolved upstream fuel-trim/misfire fault contaminating the cat — not a dead converter. Original OEM Toyota converters are robust, so a P0430 well before 150k often points at the cheaper sensor first.

    Common Symptoms

    • Check engine light on
    • Failed emissions/smog test
    • Slightly reduced fuel economy
    • Faint sulfur/rotten-egg exhaust smell in some cases
    • No obvious drivability change

    How to Fix

    Diagnose before spending: read live downstream O2 data and clear/monitor before condemning the converter. Replace the Bank 2 downstream (Sensor 2) oxygen sensor first if it is slow-switching; fix any upstream misfire or rich/lean fuel-trim codes that can poison the cat. If P0430 returns with a confirmed-good downstream sensor, replace the Bank 2 catalytic converter (use a CARB-compliant or OEM unit to avoid an immediate repeat code). Toyota specifies replacing front and rear catalyst sections together when a cat is truly bad.

    On the 2005-2015 Toyota Tacoma, second-generation Tacomas commonly develop failure of the steering wheel spiral cable, also called the clock spring. Owners report the airbag warning light turning on along with loss of horn, cruise control, or steering wheel audio controls because the ribbon cable inside the assembly breaks with repeated wheel rotation. Toyota issued service information and the problem is widely documented in owner forums and complaint databases.

    Common Symptoms

    • airbag warning light on
    • horn not working
    • cruise control inoperative
    • steering wheel audio buttons not working
    • intermittent electrical functions when turning wheel

    How to Fix

    Scan the SRS system first and confirm continuity loss through the spiral cable before replacing other parts. Replacement of the clock spring assembly is the standard repair; after installation, the steering angle and wheel centering should be verified and SRS codes cleared. Care is required because the driver airbag must be removed safely.

    On the 2005-2015 Toyota Tacoma, second-generation Tacoma owners frequently report front wheel bearing wear that starts as a low humming or growling noise and can progress to looseness, vibration, and ABS sensor issues because the sensor tone ring is integrated with the hub assembly. Heavier tires, off-road use, and added front-end load appear to accelerate failure on some trucks. The issue is widely discussed in Tacoma forums and commonly seen in repair shops.

    Common Symptoms

    • humming or growling from front wheel area
    • noise increases with vehicle speed
    • noise changes when turning left or right
    • steering vibration
    • ABS or traction light in severe cases

    How to Fix

    Diagnosis includes road-testing for a speed-dependent hum, checking for play with the wheel off the ground, and comparing noise while loading each side in turns. Repair usually involves replacing the affected front hub/bearing assembly or pressing in a new bearing depending on model configuration, followed by alignment verification and ABS sensor inspection. Using quality OEM/Koyo components is commonly recommended.

    On the 2005-2015 Toyota Tacoma, a very common Tacoma problem is a broken plastic tailgate handle or stretched/bound latch rods that leave the tailgate stuck shut or unable to latch properly. Owners frequently report the handle feeling loose or snapping internally, especially in cold weather or after repeated use. The issue is well documented in owner forums and repair databases, and many trucks need the handle assembly replaced more than once.

    Common Symptoms

    • tailgate will not open
    • tailgate handle feels loose or broken
    • tailgate only unlatches on one side
    • tailgate sticks shut
    • tailgate will not stay latched

    How to Fix

    Diagnosis involves removing the tailgate access panel, checking whether the handle pivots normally, and inspecting the latch rods, clips, and both side latches for binding or breakage. The usual fix is replacing the handle assembly and damaged clips, then lubricating and adjusting the latch rods so both latches release evenly. Metal aftermarket handles are a common durability upgrade over the original plastic part.
