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.
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.
Call to confirm they can assess your vehicle and perform the stated work. Search results do not confirm qualification, eligibility or coverage.
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 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. More than 170 engine complaints were filed for the 2006 model year. A small number of owners also report under-hood smoke or fire, but none of these reports has been tied to the PCM.
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. 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.
Call to confirm they can assess your vehicle and perform the stated work. Search results do not confirm qualification, eligibility or coverage.
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

On 3.0L Hurricane twin-turbocharged engines, direct fuel injectors have been reported to develop external fuel leaks at the injector body O-ring seals, allowing raw fuel vapor into the engine bay. The high-pressure direct injection system operates at significantly elevated pressures, and thermal cycling degrades the injector sealing rings prematurely. Owners report a strong fuel odor inside the cabin and in the engine compartment, sometimes accompanied by a visible wet spot or fuel staining on the intake manifold area.
Common Symptoms
- Strong fuel smell inside the cabin
- Fuel smell in the engine bay
- Wet spot or fuel staining around the intake manifold
How to Fix
Replace high-pressure direct fuel injector O-ring seals and injector cups as a set using updated Mopar injector seal kits. All six injectors should be inspected and resealed simultaneously. If the injector body is cracked or the pintle is damaged, full injector replacement is required.

The Bosch CP4.2 high-pressure fuel pump on the 3.0L EcoDiesel relies on diesel fuel for lubrication of its roller-lifter cam followers. US ultra-low-sulfur diesel has far less lubricity than the European fuel the pump was designed around, so the follower can lose contact with the cam, scuff, and grind itself apart. The resulting steel debris is pumped downstream through the rails and injectors, contaminating the entire fuel system. This drove a safety recall covering 2021-2023 Gladiator (and Wrangler) EcoDiesels; the failure typically strands the truck without warning.
Common Symptoms
- Sudden loss of power and stall with no restart
- Extended cranking / no start
- Check engine light with fuel rail pressure faults
- Metallic glitter in the fuel filter
- Hard starting or rough running before total failure
How to Fix
Confirm and complete any open HPFP recall (NHTSA campaigns 22V767 and 23V263). On a failed pump the correct repair is not just the pump - injectors, rails, lines, filters and often the tank must be cleaned or replaced or the debris takes out the new pump. Preventively, owners run a lubricity-improving diesel additive (or a biodiesel blend) at every fill; some install an aftermarket CP3 conversion or a disaster-prevention filter kit as a permanent fix, though that can affect warranty.

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 5 models: Grand 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 $100 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.
