If routine diagnosis using SI does not reveal any obvious cause for the DTC setting, and you have reviewed PIP3746A, then reprogram the PCM.

concern. This calibration, or any that follow, is designed to address this concern.
The new PCM calibration is available to dealerships in TIS2WEB (website version of TIS) version. If you cannot access the calibration, please call the
