How to diagnose and fix P069E: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Buick Envision · 2021–2023
Second-generation Envisions have a repeating NHTSA pattern of the fuel pump control module failing, producing an engine that dies without warning while driving and a crank-no-start afterward, or that only fires on 7-8 of every 10 attempts. Owners report no warning lights and no stored codes in several cases. One especially dangerous report describes the vehicle stalling in a center freeway lane where the electronic shifter would not allow neutral with the engine off, stranding the car in traffic. Failures are documented from about 11,000 miles, and replacement modules have been back-ordered for extended periods.
Common Symptoms
- Engine dies while driving with no warning
- Cranks but will not start, intermittently
- No check engine light or stored trouble codes at the time of failure
- Vehicle stalls and cannot be shifted to neutral to be pushed
How to Fix
Check fuel pressure and fuel pump power/enable at the module before replacing the pump assembly. The repair is replacement of the fuel pump control module (typically mounted at the rear of the vehicle) followed by module programming. Check GM's open recall and field-action list against your VIN, and verify the vehicle's shift-to-neutral procedure with the engine off so you can move it if it strands you.

RAM 2500 · 2006–2018
The TIPM is the central under-hood fuse/relay and power-distribution computer that controls the fuel pump, lighting, wipers, door locks, horn, and trailer-tow circuits. It is a widespread failure point on 2007-2016 Ram trucks. The most common complaint is the internal fuel pump relay sticking: stuck ON causes overnight battery drain and the pump running with the key off, while stuck OFF causes intermittent no-start / stalling. Other failures include inoperative wipers, dead door locks, non-working turn signals/high beams, phantom horn, and dead trailer lights. Root causes include water intrusion into the layered module and improperly spliced aftermarket accessories overloading circuits.
Common Symptoms
- No-start or intermittent crank-no-start
- Fuel pump runs with key off / dead battery overnight
- Wipers, door locks, or horn inoperative
- Turn signals or headlights not working
- Trailer tow lights dead
- Random electrical gremlins / stalling
How to Fix
Diagnose which circuit is affected before replacing. A stuck fuel pump relay can be temporarily addressed with an external fuel-pump relay bypass harness, but the durable fix is to rebuild the existing TIPM (specialist shops like Circuit Board Medics repair the boards/relays) or replace it with a new module that must be programmed to the VIN. Remove any improper accessory splices feeding off TIPM circuits. Inspect for and seal water intrusion at the module.

Frequently asked questions
What does P069E mean?
P069E stands for "Fuel Pump Control Module Requested MIL Illumination." The fuel pump control module (FPCM) — the separate computer that drives the in-tank fuel pump based on the engine control module's pressure demand — has found a fault in the fuel supply system and asked the powertrain control module to turn on the check engine light. The code itself is a hand-off notice, so the actual defect is usually stored as an additional code inside the FPCM. Drivers commonly see hard starting, no-start, stalling, or a loss of power under load. Note that many vehicles use a simple fuel pump relay rather than an FPCM and will never set this code.
What are the most common causes of P069E?
The most common causes of P069E are: Failing or weak in-tank fuel pump, Faulty fuel pump control module or its internal driver, Fuel pressure sensor reading out of range, Wiring, connector, or ground faults between the ECM, FPCM, and pump, Blown fuse or failed fuel pump relay / low system voltage, Clogged fuel filter or restricted fuel supply causing low pressure. The specific cause varies by vehicle.
How much does it cost to fix P069E?
Repair costs for P069E range from $300 to $1,400, depending on the vehicle and root cause.
