P0452 and P0453
WARNING: This page is about a different variant/trim than selected.
- The ECM illuminates the MIL on the second consecutive ignition cycle that the diagnostic runs and fails.
- The ECM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the ECM stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the ECM records the operating conditions at the time of the failure. The ECM writes the operating conditions to the Freeze Frame and updates the Failure Records.
