Trouble Code Identification
WARNING: This page is about a different variant/trim than selected.
NOTE:
Trouble codes retrieved from PCM may be either engine or transmission related. Only engine related DTCs are covered in this article. For transmission related DTCs, see appropriate AUTO TRANS DIAGNOSIS article, AUTO TRANS DIAGNOSIS - 4L80-E - 2 DIGIT CODES
or AUTO TRANS DIAGNOSIS - 4L80E(DIESEL) - 4 DIGIT CODE
in the AUTO TRANS DIAGNOSIS section for domestic vehicles. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table to determine if DTC is engine or transmission related.
- The DTCs indicate failure of a specific sensor and/or circuit. Sensor/circuit diagnosis may indicate replacement of PCM.
- If PCM is replaced at any point during diagnostic testing and if condition is still not corrected after replacing PCM, the following may be the cause:
- An incorrect PCM may cause a malfunction, which may or may not set a DTC.
- The PCM connector may be the problem. Connector terminals may have to be removed from connector to be properly checked.
- Replacement PCM may be faulty.
- Intermittent problem. Make a careful physical inspection of affected sensor/circuit.
- A shorted solenoid, coil relay, or harness may be the cause of PCM failure. Use Short Circuit Tester (J-34636) to check for short circuits.
