When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1002 fault code.

  • The symptoms of the automobile fault code p1002 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1002 can be caused by a faulty ignition switch, open or shorted ignition switch harness, poor electrical connection in the ignition switch circuit, or a faulty cabin compartment node (CCN).

  • The fault code P1002 can be caused by the following: a faulty ignition switch, an open or shorted ignition switch harness, a poor electrical connection in the ignition switch circuit, and a faulty cabin compartment node (CCN).

To fix the p1002 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1002, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1002 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P1002 fault code refers to the Ignition Key Off Timer Performance being too slow.

This code is related to the Transmission Control Module (TCM) and its ability to perform diagnostic tests when the ignition is turned off. The TCM relies on the ignition off timer, which is stored in the Cabin Compartment Node (CCN) and sent to the Totally Integrated Power Module (TIPM) over the CAN bus.

The TCM compares the ignition off timer value to the Engine Coolant Ignition off temperature and the Engine Coolant Start-up Temperature message.

If the ignition off time is less than a calibrated value based on these temperatures, the P1002 code will be triggered.

This code indicates that the TCM is not able to perform the necessary diagnostic tests within the proper enable conditions. If you encounter the P1002 fault code, it is important to have your vehicle inspected by a qualified technician.

They will be able to diagnose the specific cause of the code and recommend the appropriate repairs.

Ignoring this code could lead to further damage or performance issues with your vehicle.

What are the possible causes for the automobile fault code P1002 and how can I visually inspect them?

If you’re seeing the P1002 fault code and your engine light is on, there are a few possible causes to consider. It could be a faulty ignition switch, an open or shorted ignition switch harness, a poor electrical connection in the ignition switch circuit, or a faulty cabin compartment node (CCN). To visually inspect these potential issues, check the related wiring harness and connectors. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded. Taking these steps can help you identify and address the problem.

How does a faulty ignition switch or a poor electrical connection in the ignition switch circuit lead to the engine light being ON?

When the engine light is ON, it could be due to a faulty ignition switch or a poor electrical connection in the ignition switch circuit. This can happen if the ignition switch itself is faulty, if the ignition switch harness is open or shorted, or if there is a poor electrical connection in the ignition switch circuit. Another possible cause could be a faulty Cabin Compartment Node (CCN). To fix this issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.

What steps can I take to fix the P1002 fault code and ensure that the related wiring harness and connectors are in good condition?

To fix the P1002 fault code and ensure the wiring harness and connectors are in good condition, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Additionally, check the possible causes listed above, including a faulty ignition switch, open or shorted ignition switch harness, poor electrical connection in the ignition switch circuit, or a faulty Cabin Compartment Node (CCN). Taking these steps will help identify and address any issues causing the fault code.
