Code P1001 2012 Ford Fusion Description

The Key On/Engine Running (KOER) on-demand self-test is a functional test of the Powertrain Control Module (PCM) carried out on-demand with the ignition ON, the engine running, and the vehicle stopped. A check of certain inputs and outputs is made during operating conditions and at a normal operating temperature. The brake pedal position, transmission control, and the power steering tests are part of the KOER on-demand self-test and must be carried out during this operation if applicable.
The Powertrain Control Module sets the non-MIL (Malfunction Indicator Lamp) Diagnostic Trouble Code (DTC) when the Key On/Engine Running (KOER) self-test does not complete in the time intended.
