P0087 on Jeep by model: symptoms, diagnosis and fix
The Totally Integrated Power Module (TIPM) can fail, causing various electrical issues including fuel pump relay problems (no start), random horn honking, and erratic behavior of lights and accessories.
Common Symptoms
- No start condition
- Fuel pump not priming
- Random horn honking
- Headlights flickering
- Wipers activating randomly
- Battery drain
How to Fix
For fuel pump relay failure: Install an external bypass relay kit ($30-50 DIY) to power fuel pump directly. For complete fix: Replace TIPM unit with remanufactured unit ($400-600) or new OEM ($800-1,200). Some electrical shops can repair/rebuild existing TIPM for $200-400.

Certain 2014-2020 Jeep Grand Cherokee (WK) vehicles with the 3.0L diesel engine are included in safety recall Z46 / NHTSA 22V-406. The high-pressure fuel pump can fail prematurely and introduce internal debris into the fuel system, causing fuel starvation. FCA says occupants may notice a malfunction indicator lamp, a fuel leak, abnormal engine noise, or a change in drive quality; fuel starvation can cause an unexpected loss of motive power and increase crash risk. Recall inclusion is VIN-specific. The prior card incorrectly included 2021-2023 vehicles and treated an old pump number plus a retail injector set and filters as a universal repair.
Common Symptoms
- Unexpected loss of motive power or stalling
- Malfunction indicator lamp
- Fuel leak
- Abnormal engine noise
- Change in drive quality or a non-running condition
How to Fix
Check the VIN for open recall Z46 and schedule the free repair with an authorized Jeep dealer. FCA's procedure is condition-dependent: a vehicle delivered in good running condition receives the campaign HPFP and associated non-contaminated-system service, while a non-running vehicle is diagnosed for pump failure and, when contamination is confirmed, receives the pump, in-tank modules, filters, injectors, rails, high-pressure tubes, fuel-system cleaning, and other campaign items specified for that vehicle. If the vehicle stalls, loses power, leaks fuel, or will not restart, move it to a safe location, shut it off, and arrange a tow rather than continuing to run the engine. Do not buy a retail CP4 pump, injector set, or filter bundle before VIN eligibility and contamination status are established.

Owner tips & cautions
- WarningRecall eligibility is VIN-specific. Do not assume every 2014-2020 EcoDiesel is included, and do not extend this card to 2021-2023 vehicles.
- WarningDo not order the old 68211269AA pump or a universal injector/filter bundle as the recall fix. FCA's dealer kits and component scope change depending on whether pump failure and contamination are present.

The TIPM can develop internal relay failures causing various electrical problems including fuel pump not activating, horn honking randomly, wipers activating on their own, and other erratic electrical behavior. This is a well-known issue across Chrysler vehicles.
Common Symptoms
- No start condition (fuel pump not running)
- Horn honking randomly
- Wipers activating on their own
- Power windows inoperative
- Multiple electrical systems failing
- Lights flickering
How to Fix
TIPM replacement is the definitive fix but expensive. External bypass relays can be installed for specific failing circuits (fuel pump relay bypass is common). Used TIPMs available but may have similar issues. Some shops rebuild TIPMs.

The Totally Integrated Power Module fuel pump relay fails, causing no-start conditions or fuel pump running continuously. Unlike older models, the relay is integrated and cannot be replaced separately.
Common Symptoms
- Hard starting or no start condition
- Multiple cranking attempts needed
- Fuel pump runs continuously after shutting off
- Dead battery from fuel pump running
- Starting issues worse when cold
How to Fix
Options include TIPM replacement ($1,500-2,000), professional TIPM repair service ($300-500), or external relay bypass installation ($75). TIPM repair services can complete work within 24-48 hours.
Owner tips & cautions
- TipTIPM repair services ($300-500) more cost-effective than dealer replacement
- TipExternal relay bypass kits available for ~$75 (DIY solution)

The Commander can stall or lose engine power without warning at any speed. The problem is linked to multiple causes: faulty crankshaft position sensor, failing fuel pump, PCM software bugs, and throttle body issues. Over 173 engine complaints were filed for the 2006 model year. Some owners report engine compartment fires linked to electrical shorts in the PCM area.
Common Symptoms
- Engine stalls without warning
- Loss of power during acceleration
- No-start condition (cranks but no start)
- Check engine light with P0335/P0340 codes
- Intermittent rough idle
- Engine cuts out at highway speed
How to Fix
Replace the crankshaft position sensor (Mopar 56028373AB, $20-40 part, $100-200 labor) as the most common fix. Clean or replace the throttle body ($150-300). Check fuel pump pressure (should be 49-55 PSI). Update PCM software to the latest calibration at the dealer. For fire risk concerns, inspect wiring harness in the engine bay for chafing or heat damage.
Owner tips & cautions
- TipCarry a spare crankshaft position sensor in the glove box - they are known to fail without warning and the repair takes 15 minutes
- WarningStalling at highway speed is extremely dangerous - address this issue immediately

Owners report sudden and complete loss of power while driving at highway speeds without warning. The engine may stall, lose throttle response, or go into limp mode unexpectedly. Contributing factors include throttle body failure, fuel pump issues, and PCM software bugs. This is especially dangerous on highways as power steering and power brakes are compromised when the engine stalls.
Common Symptoms
- Complete loss of engine power while driving
- Check engine light with multiple codes
- Throttle unresponsive to pedal input
- Vehicle enters limp mode
- Engine shuts off at highway speed
- Power steering becomes heavy (stalled engine)
How to Fix
Have dealer check for TSBs related to PCM software updates first. Inspect and clean the throttle body (Mopar 04891735AC for 2.4L). Check fuel pump pressure and replace if below spec. In some cases, the TIPM (Totally Integrated Power Module) may need replacement or relay bypass. If recurring, have wiring harness inspected for chafing or shorts.
Owner tips & cautions
- WarningIf the engine stalls at speed, shift to neutral, turn on hazards, and coast to a safe stop - do not try to restart while moving at speed
- TipKeep the PCM software updated - several calibrations have been released to address stalling conditions

Frequently asked questions
What does P0087 mean on a Jeep?
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On Jeep it is documented across 7 models: Grand Cherokee, Wrangler, Cherokee, Commander, Renegade, Grand Wagoneer, Gladiator.
What are the most common causes of P0087?
The most common causes of P0087 are: Clogged or dirty fuel filter, Weak or failing fuel pump (lift pump or high-pressure pump), Faulty fuel pressure regulator or control valve, Restricted or leaking fuel lines, Faulty fuel pressure sensor, Air in the fuel system or running low on fuel, Worn high-pressure pump (direct injection/diesel). The specific cause varies by vehicle.
How much does it cost to fix P0087 on a Jeep?
Published repair estimates on Jeep range from $75 to $12,000 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.
