P0022 on Ford by model: symptoms, diagnosis and fix
Two distinct tick patterns affect 5.0L Coyote V8 in 2015-2023 Mustang depending on engine generation. Gen 2 Coyote (2015-2017): light tick at idle and on cold start, commonly attributed to valve lash / lifter operation; generally cosmetic and not associated with engine damage. Gen 3 Coyote (2018-2023): louder, more pronounced tick — same family but Ford changed to plasma transferred wire arc (PTWA) cylinder liners. The tick is increasingly linked to piston slap from clearance issues against the plasma liner, with some confirmed cases of cylinder wall scoring requiring engine replacement under warranty. Direct injection (added on Gen 3 alongside port injection) contributes a separate fainter HPFP tick that is normal. Distinguishing: Gen 2 tick stays constant warm; Gen 3 piston slap diminishes as engine warms but returns under load. Owner forums (Mustang6G, MPR Racing Engines) document the Gen 3 pattern extensively.
Common Symptoms
- Tick or tap noise at idle
- Typewriter-like clicking sound
- Metallic rattle on cold start
- Noise that diminishes when warm
- Ticking more pronounced after oil change
How to Fix
Ford TSB 14-0156 addresses this as a normal characteristic, stating no repair should be attempted. Using Ford's recommended oil (Motorcraft 5W-20 or 5W-30) and changing oil at 5,000-mile intervals may help. For persistent issues, VCT solenoid replacement ($200-400) or cam phaser service ($1,500-3,000) may help.

The 5.0L Coyote V8 can develop a ticking or rattling noise at startup, often from the cam phasers. This is similar to issues in the Mustang GT. The noise typically diminishes after the engine warms up but can indicate phaser wear.
Common Symptoms
- Ticking noise at cold startup
- Rattle from top of engine
- Noise diminishes when warm
- Louder in cold weather
- Check engine light in severe cases
How to Fix
Use quality synthetic oil and change regularly. Ford updated cam phaser design for later production. If noise is excessive, cam phaser replacement may be needed. Check for TSBs specific to your build date.

The 2nd-generation 3.5L EcoBoost V6 in 2018-2022 Ford Expedition (Gen 4) addressed the timing chain stretch issue of early-generation 3.5L EcoBoost engines (2011-2016) but introduced a new problem: VCT (Variable Camshaft Timing) unit wear that causes a distinctive ticking/tapping rattle on cold starts after a 6+ hour soak. The rattle typically lasts 2-5 seconds and comes from the top front of the engine. Ford issued TSB addressing the condition for 2018-2019 Expedition/Navigator, recommending VCT unit replacement. The cam phasers become sticky when oil drains back overnight, then rattle until fresh oil pressure reaches them.
Common Symptoms
- Ticking/tapping rattle from top-front of engine on cold start
- Rattle lasts 2-5 seconds then disappears as oil pressure builds
- Only occurs after vehicle has sat for 6+ hours
- Check engine light with P0011, P0012, P0021, P0022 (cam timing codes)
- Rough running until engine warms
- Reduced power on cold start
How to Fix
Ford TSB for 3.5L EcoBoost cold-start rattle: replace VCT units (both banks). Use only Ford-spec 5W-30 full synthetic oil (Motorcraft SAE 5W-30 Full Synthetic). Ensure oil changes are performed on schedule - contaminated or degraded oil worsens VCT phaser wear. Some owners report improvement with more frequent oil changes. VCT replacement is approximately 6-8 hours labor on Expedition.

The 3.5L/3.7L Duratec V6 in first-generation Ford Edge commonly develops timing chain stretch and variable camshaft timing (VCT) phaser rattles between 80,000-120,000 miles. The engine uses two timing chains (one per cylinder bank) that can stretch over time, causing the VCT phasers to rattle loudly on cold starts as oil pressure builds. The rattle typically lasts 2-5 seconds on startup before oil pressure stabilizes. Left unaddressed, chain slack can cause timing to jump, resulting in rough running, poor fuel economy, and potential catastrophic engine damage if a chain breaks or a guide fails.
Common Symptoms
- Loud rattling noise from engine on cold start (first 2-5 seconds)
- Rattle disappears once oil pressure builds
- Check engine light with P0011, P0016, P0017, P0021, P0022 codes (VCT/timing correlation)
- Rough idle or engine shaking
- Poor fuel economy
- Loss of power on acceleration
- Engine hesitation
How to Fix
Replace timing chains, guides, tensioners, and VCT phaser units as a complete kit. Motorcraft timing chain kit (part number TKIT-003-MG) includes all wear components. Use full-synthetic 5W-20 oil and change every 5,000-7,500 miles to extend chain life. Labor is 8-12 hours on an Edge due to front engine access. Cost is substantially lower if done proactively vs. after a guide failure.

On the 3.0L Duratec V6, the camshaft bearing cap bolts — particularly the rearmost caps — work loose on their own over time. Owners on escape-city document caps found well under specified torque during valve cover gasket jobs on cars with no prior top-end work. As the cap loosens, the camshaft journal loses its clamp load: the engine develops a rattle or tick from the top end, oil pressure at the cam journal drops, and the variable cam timing phaser starts behaving erratically, throwing cam timing correlation codes. If left alone, a cap bolt can back out or snap, which lets the cam walk and destroys the head. It compounds a second well-known 3.0L weakness: the valve cover gasket leaks oil onto the alternator, and shops that replace the alternator without curing the leak see it fail again. This is 3.0L Duratec V6 specific — it is not a failure of the 2.0L Zetec, the 2.3L or 2.5L four-cylinders.
Common Symptoms
- Rattle or tick from the top of the engine, worst on cold start
- Ticking that changes with engine speed
- Oil leak from the camshaft/valve cover down onto the alternator
- Alternator failing repeatedly after replacement
- Engine hesitation and sluggish acceleration
- Cam timing correlation check engine light
How to Fix
Pull the camshaft covers and check every cam bearing cap bolt against specification with a torque wrench. Replace the cap bolts with new Ford bolts one cap at a time — never loosen more than one cap at a time, or the cam will lift — and use thread locker on reassembly as forum owners and independent shops recommend. Replace the camshaft cover gaskets at the same time, since the job is already open and the oil leak onto the alternator is the other half of the problem. If the rattle persists after retorquing, inspect the cam phasers, VCT solenoids and the timing chain guides, since a long-running low-clamp condition damages all three. Timing chain and guide replacement on this engine is labor-intensive and typically requires pulling the engine and transaxle as an assembly.

The 3.5L Duratec V6 in later model Taurus vehicles develops cam phaser rattle on cold starts due to worn variable valve timing actuators and depleted oil control valve seals.
Common Symptoms
- Rattling noise on cold start
- Check engine light
- Rough idle when cold
How to Fix
Confirm the noise is coming from the front timing cover area during a cold start, then scan for VCT-related DTCs such as P0011, P0012, P0021, or P0022 and verify oil level/condition and oil pressure first, since dirty or low oil can aggravate phaser noise. The proper repair is to replace the worn cam phasers and VCT/OCV solenoids, and on higher-mileage engines it is wise to install new timing chains, guides, tensioners, and related seals/gaskets because the front cover must be removed to access the components. After reassembly, perform an oil and filter change with the correct viscosity oil, clear codes, and verify quiet cold-start operation; typical repair cost is about $1,500-$3,000 depending on whether only phasers/solenoids are replaced or a full timing set service is done.

Frequently asked questions
What does P0022 mean on a Ford?
P0022 stands for "Intake Camshaft Position Timing - Over-Retarded (Bank 2)." This code means the engine computer found that the intake camshaft on bank 2 is timed too far retarded — more delayed than it commanded through the variable valve timing (VVT) system. The computer adjusts cam timing using an oil-controlled actuator (a phaser) and an electric solenoid, then verifies the cam actually moved to the target position. When the intake cam on bank 2 lags behind its commanded position, this code sets, often causing rough idle, reduced power, or lower fuel economy. (Bank 2 is the cylinder bank that does not contain cylinder 1.) It usually traces back to oil flow, the VVT solenoid, or the phaser. On Ford it is documented across 7 models: Mustang, F-150, Expedition, Edge, Escape, Taurus, Bronco.
What are the most common causes of P0022?
The most common causes of P0022 are: Low or dirty engine oil restricting VVT operation, Stuck or clogged camshaft (VVT) oil control solenoid, Clogged VVT oil passages or screen, Worn camshaft phaser/actuator on bank 2, Stretched or worn timing chain affecting cam timing, Electrical fault in the VVT solenoid wiring or connector, Incorrect oil viscosity or overdue oil change. The specific cause varies by vehicle.
How much does it cost to fix P0022 on a Ford?
Published repair estimates on Ford range from $300 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
