Fuel Pump Control Module Requested MIL Illumination
The P069E code indicates that the fuel pump control module (FPCM) has detected a fault and requested the powertrain control module (PCM) to illuminate the malfunction indicator lamp (MIL). This typically points to an issue within the fuel pump control circuit, such as a faulty FPCM, wiring problems, or a defective fuel pump. The FPCM monitors fuel pump operation and if it sees abnormal voltage, current, or communication errors, it triggers this code.
1. Most Common Causes
- Internal failure of the Fuel Pump Control Module (FPCM)
- Poor communication between the FPCM and PCM (CAN bus issue)
- Faulty fuel pressure sensor or erroneous signal
- Fuel pump motor problem (overcurrent, seizure, or wear)
- Damaged, corroded, or shorted wiring or connectors at the FPCM
- Faulty FPCM power relay
- Software update needed for the FPCM or PCM
- Abnormal supply voltage (low or high battery voltage)
2. Symptoms You Will Notice
- Check Engine Light on
- Engine may crank but not start
- Reduced fuel economy
- Engine stalling or hesitation
3. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data to identify related issues.
Step 2: Inspect the fuel pump control module and wiring for damage, corrosion, or loose connections.
Step 3: Test fuel pump operation by listening for prime on key-on or checking fuel pressure.
Step 4: Use a multimeter to check power, ground, and signal circuits at the FPCM connector.
Step 5: If all else is normal, replace the fuel pump control module and clear codes.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The vehicle may stall or fail to start, posing a safety risk. Have it diagnosed promptly.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Repair costs vary: a fuel pump control module replacement can be $200-$400, while wiring repairs may be less.
