This article is being republished in its entirety to update the Calibration Information.
ISSUE:
Some vehicles may exhibit a Malfunction Indicator Lamp (MIL) illumination along with a P0420 Diagnostic Trouble Code (DTC) stored in continuous memory with no driveability concerns. This may be caused by the calibration of the Powertrain Control Module (PCM).
ACTION:
If no other failures are observed during normal diagnosis, (physically damaged catalyst, stuck fuel injectors, etc.), reprogram the PCM with the latest level calibration in the application chart. PCM reprogramming should be performed before any emission hardware is replaced. If the vehicle already has the latest calibration, follow normal diagnostic procedures for DTC.
NOTE: PCM REPROGRAMMING SHOULD BE PERFORMED BEFORE ANY EMISSION HARDWARE IS REPLACED.
