Diagnostic Trouble Code Definitions

  1. The Diagnostic Trouble Codes (DTCs) indicate failure of a specific sensor and/or circuit. Sensor/circuit diagnosis may indicate replacement of PCM.
  2. 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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
