- Wiring issues: Problems with the wiring harness or electrical connections can also cause the C1201 code to be set.
- Engine control module (ECM) issues: In some cases, the C1201 code can be caused by a problem with the ECM itself, such as a faulty component or a software issue.
- Fuel system problems: Issues with the fuel system, such as a clogged fuel filter or a problem with the fuel injectors, can also trigger the C1201 code.
To diagnose and resolve the C1201 code, it is important to use a diagnostic tool to read the code and identify the specific problem. Once the root cause of the issue has been identified, the necessary repairs can be made to resolve the problem and clear the code.
Resolving the C1201 Code
