CHEVROLET · 2017-10-01

Malfunction Indicator Lamp (MIL) Illuminated - DTC P015B Set Condition-Some customers may comment that the MIL is illuminated. The technician may find DTC P015B set. Cause This condition may be caused by the Engine Control Module (ECM) calibration too sensitive in setting DTC P015B. Correction-Note: Do Not replace the O2 sensor until the latest ECM calibration has been validated. Validate the ECM has the latest software calibration: • If the ECM is not at the latest calibration, it must be reprogrammed to the latest software calibration available. • If the ECM has the latest calibrations, refer to SI for the DTC set.
