P069E OBD-II Fuel Pump Module Requested Mil Illumination Trouble Code

The P069E code is an OBD-II trouble code that stands for fuel pump control module (FPCM) Requested Mil Illumination.

The fuel pump control module (FPCM) is responsible for managing the fuel pump and making sure that it provides the correct pressure and flow rate of fuel to the engine.

In this article, I will be talking about the P069E trouble code, its symptoms, causes, and how to fix it.

What Does The P069E Code Mean?

P069E OBD-II Fuel Pump Module Requested Mil Illumination Trouble Code

The P069E trouble code means that there is a problem with the electrical circuit that controls the fuel pump control module (FPCM) relay, which regulates the operation of the fuel pump.

Typically, the P069E trouble code indicates that the voltage in the fuel pump control module (FPCM) relay control circuit is lower than recommended.

This might be caused for various reasons like a faulty relay, wiring problems, or a faulty FPCM.

The engine control module (ECM) or FPCM requests the powertrain control module (PCM) to illuminate the check engine light and to report data from many modules (fuel pump, fault code, etc..). If the issue is not resolved within 45 seconds of the initial request, a P069E code with an extended resolution time can be generated.

This code is utilized by a variety of American manufacturers, including Buick, Cadillac, Chevrolet, Ford, GMC, and many others. The definition’s specifics, in addition to troubleshooting and repairs, will vary by brand and model.

What Are The Possible Causes of the P069E Code?

The possible causes of the P069E trouble code are:

  • A defective fuel pump
  • The circuit supplying the fuel pump control module is open
  • Damaged wiring
  • A faulty fuel pressure relay
  • Voltage cutoff (inertia) switch for a faulty or malfunctioning fuel pump.
  • A problem with the fuel pump control module (FPCM) or engine control module (ECM)

Is It Safe To Drive With a P069E Code

Yes, it is safe to drive with the P069E trouble code. This code is not considered serious, but it is still something that you need to deal with.

As I said this code indicates an issue with the fuel pump relay control circuit, which is responsible for regulating the operation of the fuel pump. If the fuel pump is defective, the engine may experience poor performance, slow acceleration, and even a no-start condition.

Furthermore, if the check engine light is illuminating on the vehicle’s dashboard and you continue driving your vehicle, this can mask other potential issues that may arise if you do not fix this on time.

In such a situation, the driver is not alerted of the additional trouble codes or warning lights that may occur.

How To Diagnose The P069E Code

Here is how to diagnose the P069E trouble code:

  1. Use an OBD-II scan tool and scan the vehicle to see if any codes accompany the P069E trouble code, and clear the engine warning light.
  2. Scan the document data from the freeze frame to determine when the P069E code is set.
  3. Start with troubleshooting and repairs
  4. If all of the fuel pump’s fuses are in place, the fuel pump circuit may be malfunctioning. Test the voltage at the fuel pump wire harness of the powertrain control module. If electricity is available when measuring 12 volts with the ignition on but none is recorded when the engine is started then there is a problem with the wiring harness.
  5. If there is enough power to deliver current to the fuel pump controller, but not enough to activate the fuel pump, check the resistance between terminals 2 and 3 in the powertrain control module (PCM) connector (depending on make/model). If resistance in this region exceeds 10,000 ohms or falls below 1,000 ohms, replace or repair the wiring harness.
  6. If there is no power to the fuel pump controller, check the resistance between terminals 2 and 3 in the PCM connector (depending on the vehicle’s make and model). Detection of resistance indicates that electricity is reaching the pump circuit. Check the wire harness for a possible short or an open. If required, repair or replace it.

Most Common Mistakes When Diagnosing The P069E Code

To avoid mistakes with the P069E trouble code, follow these guidelines:

  • Assume the fuel pump controller is responsible without examining other components.
  • Not applying the correct voltage to measure the resistance between terminals 2 and 3 in the PCM connector (varies by make and model).
  • Failure to inspect all of the vehicle’s wire harnesses for continuity, shorts, or openings when the fuel pump controller has no voltage.

What Repairs Can Fix The P069E Code?

Repairs that can fix the P069E trouble code are:

  • If the old fuel pump controller is defective, replace it with an updated model.
  • Removing or replacing a malfunctioning fuel pump controller or faulty fuses and relays.
  • Fixing or adjusting wiring harnesses to ensure that they are not damaged, shorted, or grounded.
  • Changing the voltage shutdown (inertia) switch on the car.
  • Identifying and resolving any programming errors with the powertrain control module

How To Fix The P069E Code

Here are some steps you should take to fix the P069E trouble code:

  • Replace the defective fuel pump
  • Repair or replace the damaged fuses or relays
  • Fix or replace the damaged wiring
  • Repair or replace the faulty fuel pressure relay
  • Replace the voltage shutdown switch on the vehicle
  • Replacement or reprogramming of the errors with the PCM

In Conclusion

The P069E diagnostic trouble code indicates that the fuel pump controller is malfunctioning. The fuel pump controller could require repair or replacement.

In some vehicles, repairing a faulty or tripped fuel pump may be as simple as changing a voltage shutdown (inertia) switch.

If all of the vehicle’s wire harnesses are in place and there are no shorts or holes, the PCM may contain a programming error.
