OR LOWER THAN) 2001 CAL14B. CAREFULLY READ THE NOTES BELOW FOR OTHER CONDITIONS RELATED TO THE "OXYGEN
SENSOR HEATER PERFORMANCE" CONDITION.
SYMPTOM/CONDITION:
Customer will experience MIL illumination.
DIAGNOSIS PROCEDURES:
1.
Using the Diagnostic Scan Tool (DRBIII(R)) with the appropriate Diagnostic Procedures, verify all engine/transmission systems are functioning as
designed. If other DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin.
2.
It the condition seen is a MIL "on" and either Diagnostic Trouble Code (DTC) for "Oxygen Sensor Heater Performance" (P0135 OR P0141) is
present, and the vehicle is equipped with a single upstream oxygen sensor system (see table below) perform the repair procedure. If the vehicle is
not included in the table below, perform the repair procedure and follow normal diagnostic procedures to correct the "Oxygen Sensor Heater
Performance" condition.
3.
If the MIL light is "on", and the vehicle calibration level is already at 2001 CAL14B or higher, and the DTC's for "Oxygen Sensor Heater
Performance" (P0135 OR P0141) are present, follow normal diagnostic procedures to correct the problem.
