The P1001 fault code is a non-MIL (Malfunction Indicator Lamp) Diagnostic Trouble Code (DTC) that occurs when the Key OnEngine Running (KOER) self-test fails to complete within the expected time.

This self-test is performed with the ignition ON, the engine running, and the vehicle stopped. It checks various inputs and outputs, including the brake pedal position, transmission control, and power steering. If any of these tests cannot be completed during the self-test, the P1001 code is set.

It is important to address this issue to ensure the proper functioning of the Powertrain Control Module (PCM).

What are the possible causes for the automobile fault code P1001 and how can they be visually inspected?

If you see the engine light or service engine soon warning light on, it could be due to fault code P1001. This code can be caused by incorrect self-test procedure, unexpected response from the self-test monitors, or RPM out of specification. To visually inspect the possible causes, check the related wiring harness and connectors for any damage. Look for broken, bent, pushed out, or corroded connector pins. This inspection can help identify any issues and guide you towards the necessary fix.

How does an incorrect self-test procedure or an unexpected response from the self-test monitors lead to the engine light being ON?

When the engine light is ON or the service engine soon warning light is illuminated, it could be due to an incorrect self-test procedure or an unexpected response from the self-test monitors. This can also happen if the RPM is out of specification. To fix this issue, you should check the possible causes mentioned above. Take a visual inspection of the related wiring harness and connectors, and look for any damaged components. Additionally, check for any broken, bent, pushed out, or corroded connector pins.

Why is it important to check for damaged components and inspect the wiring harness and connectors when troubleshooting the fault code P1001?

When troubleshooting the fault code P1001, it is crucial to check for damaged components and inspect the wiring harness and connectors. This is because a damaged component or a faulty wiring connection can lead to an incorrect self-test procedure, an unexpected response from the self-test monitors, or an RPM out of specification. By visually inspecting the wiring harness and connectors, and checking for any signs of damage or corrosion, you can identify and fix the underlying issues causing the fault code.
