If all of the fuel pump's fuses are in place, then there might be a problem with the fuel pump circuit.To diagnose a P069E DTC code, a technician would: Rough running, poor acceleration, and a lack of fuel pressure are experienced.Engine power is reduced or the engine stalls.A trouble code is stored and the MIL (Malfunction Indicator Lamp) is illuminated.

PCM might have a problem or a programming mistake.The circuit supplied to the control module's fuel pump is open.Voltage shutoff (inertia) switch for a bad or tripped fuel pump.A faulty fuel pump controller or PCM is to blame.The definition's specifications, as well as troubleshooting and repairs, will differ from one make and model to another. This code is used by a number of American manufacturers, but it isn't limited to Buick, Cadillac, Chevrolet, Ford, GMC, and the like. If the problem is not resolved within 45 seconds of this initial request, then an extended P069E can be generated. The ECM sends a request for the powertrain control module to turn on the check engine light and reports data from various modules (fuel pump, fault code, etc.).
