Be aware that if the crankshaft position sensor, and or timing cover, is moved, removed, replaced, or disturbed in any way, the crankshaft position sensor relearn MUST be performed. The relearn requires a scan tool capable of initiating the relearn.
Also, if there is an intermittent condition with the crankshaft position sensor, P0339 will be set in memory.
CONDITIONS FOR RUNNING THE DTC
*The MAF is 5 g/s or more.
CONDITIONS FOR SETTING THE DTC
* The measured change in engine speed is more than 1,000 RPM during a 125 ms time period, or
* The measured engine speed is 0 RPM and 4 or more camshaft position sensor pulses have occurred over a period of 2 to 3 seconds
ACTION TAKEN WHEN THE DTC SETS
* The control module illuminates the Malfunction Indicator Lamp (MIL) if a failure is detected during 2 consecutive key cycles.
* The control module sets the DTC and records the operating conditions at the time the diagnostic failed. The failure information is stored in the scan tool Freeze Frame and Failure Records.
