  • To fix the automobile fault code P1008, 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 diagnosis and fixing cost of automobile fault code p1008 are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P1008 fault code is related to the Engine Coolant Bypass Valve Command Signal Message Counter. This code indicates that there is an issue with the communication between the control modules in the vehicle. The control modules monitor the communication on the serial data circuits during normal vehicle operation.

They exchange operating information and commands. Each module maintains a transmit error counter and a receive error counter. When there are errors detected in the communication, the counter values increase.

In the case of the P1008 code, the Engine Coolant Bypass Valve Command Signal Message Counter is incorrect, triggering the diagnostic trouble code.

What are the possible causes for the automobile fault code P1008?

If you see the engine light on or the service engine soon warning light, the fault code P1008 could be the culprit. This code is often caused by a faulty engine coolant bypass valve, an open or shorted harness, or a poor electrical connection in the engine coolant bypass valve circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to check the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors related to the Engine Coolant Bypass Valve?
