2009 Dodge Challenger Crankshaft Position Sensor Intermittent MIL Illumination Diagnostic Trouble Code

This bulletin involves adding a shim to the crank sensor and verifying the condition has been corrected and only if necessary, replacing the flexplate. NOTE: This bulletin applies to models equipped with a 2.7L or 3.5L engine (sales code EER or EGG) built before October 8, 20008 (MDH 0810XX).
SYMPTOM/CONDITION: Some customers may complain of MIL illumination. No other symptoms will be noted or experienced. Further investigation by the technician may find DTC P0339 - Crankshaft Position Sensor Intermittent is set. It is possible that DTC's P0300 - Multiple Cylinder Misfire and/or P1128 - Closed Loop Fueling Not Achieved - Bank 1 and/or P1129 - Closed Loop Fueling Not Achieved - Bank 2 could be set along with P0339 - Crankshaft Position Sensor Intermittent is set. NOTE: P0339 - Crankshaft Position Sensor Intermittent must be set along with the other DTC's. If P0339 - Crankshaft Position Sensor Intermittent is not set then this bulletin does not apply.
DIAGNOSIS: Using a Scan Tool (StarSCAN®) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTC's other than P0339 with or without P0300, P1128, P1129 are present then record them on the repair order and repair other DTC's first as necessary before proceeding further with this bulletin.
