P069E Fuel pump control module requested MIL illumination

Fuel pump module requested check engine light

P069E in short

P069E means the fuel pump control module detected a fault and asked the engine computer to turn on the check engine light. The real fault is stored in that module, so read its codes. Common causes are wiring, connector or water damage and a failing module. Get it inspected soon, and stop driving if it stalls.

Many GM vehicles use a separate fuel pump control module, usually near the fuel tank or under the rear seat, to run the fuel pump at the speed the engine needs.

When that module finds an emissions-related fault in itself or its circuits, it sends a request over the vehicle network and the engine computer sets P069E and lights the check engine light. P069E is a messenger code: the details are in the fuel pump control module's own codes.

GM's service information says to fix engine computer and communication codes first, then diagnose the codes stored in the fuel pump control module. A basic code reader may only show P069E, so a scan tool that can read the module helps.

Most likely causes

  1. Damaged, pinched or rubbing wiring to the fuel pump control module

    Supported by vehicle data
    Why it ranks here
    GM found a twisted, pinched harness under the rear seat on the 2012-2014 Impala causing opens and shorts with P069E, and a dealer pointed a 2016 Colorado owner to rubbing wiring near the water pump.
    What would change this
    Rises if wiring near the module or along its route is pinched, rubbed or damaged, or the fault changes when the harness is moved.

  2. Failed fuel pump control module, including water damage

    Supported by vehicle data
    Why it ranks here
    Saturn's bulletin for the 2008-2009 Vue ties P069E with extended cranking to the fuel pump control module, and an owner reports a dealer replacing a water-damaged module on a 2009 Sierra.
    What would change this
    Rises if the module shows water entry or corrosion, or its own codes point to an internal fault with good power and grounds.

  3. Failing fuel pump or pump circuit

    Possible — needs testing
    Why it ranks here
    The module watches the pump circuit, so a pump fault can make it request the light. Confirm with the module's own codes before replacing a pump.
    What would change this
    Rises if the module stores pump circuit codes and the pump draws abnormal current.
    How to test the fuel pump

  4. Power, ground or network fault affecting the module

    Possible — needs testing
    Why it ranks here
    GM says to fix engine computer and communication codes first, since a module with poor power or communication can set faults of its own.
    What would change this
    Rises if U-codes or low-voltage codes are stored too.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read codes from the engine computer and the fuel pump control module, and check for bulletins for your vehicle.

    Low riskTool: scan tool that reads all modules, service information

  2. With the key off, inspect the fuel pump control module and its wiring for water, corrosion, pinching and rubbing (on the Impala, under the rear seat).

    Low riskTool: flashlight, service information

  3. Have a shop test power, ground and network circuits at the module and follow the diagnosis for the module's stored codes.

    Best left to a shopTool: scan tool, multimeter, wiring diagram

    Warning:Work at the fuel pump and its module involves fuel vapour; keep sparks and flames away.

Symptoms

  • Check engine light on
  • Long cranking before starting
  • Engine stalls while driving or when slowing Gets more serious: stop and have it checked.
  • Cranks but will not start Gets more serious: stop and have it checked.

How to fix

  1. Have the fuel pump control module's own codes read; P069E alone does not say what failed.

  2. Write down all codes and freeze-frame data before clearing anything.

Parts and cost context

  • Fuel pump:P069E alone does not prove the pump or module failed; read the module's codes and check its wiring first.
