Introduction

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
PCM P0315:00	Crankshaft Position System Variation Not Learned: No Sub Type Information	Sets when the PCM has not learned the crankshaft pulse wheel tooth spacing. This DTC disables the misfire monitor. The misfire monitor neutral profile correction must be relearned after any engine rotational component installation or repair. Carry out the Misfire Monitor Neutral Profile Correction procedure using the scan tool. Refer to the Flash EEPROM , Neutral Profile Correction.
PCM P0335:00	Crankshaft Position Sensor 'A' Circuit: No Sub Type Information	Sets when the PCM detects the CKP sensor PIP pulse is missing for greater than a calibrated number of camshaft revolutions when the camshaft speed exceeds the equivalent speed of engine idle or the starter motor is engaged. An inactive CKP signal causes a no start condition. Monitor the RPM PID while cranking the engine. A value of 0 RPM indicates a CKP concern.
PCM P0339:00	Crankshaft Position Sensor 'A' Circuit Intermittent: No Sub Type Information	Sets when the PCM detects several erratic PIP pulses have occurred in the CKP sensor signal within a calibrated time period when the camshaft speed exceeds the equivalent speed of engine idle or the starter motor is engaged.
PCM P033F:00	Crankshaft/Camshaft Loss Of Synchronization: No Sub Type Information	Sets when the PCM detects the input signal from the CKP sensor or the CMP sensor is erratic.
PCM P1336:00	Crankshaft/Camshaft Sensor Range/Performance: No Sub Type Information	Sets when the PCM detects the input signal from the CKP sensor or the CMP sensor is erratic.
PCM P2617:00	Crankshaft Position Output Circuit/Open: No Sub Type Information	Sets when the PCM detects the CKP sensor bias voltage is less than the calibrated minimum or greater than the calibrated maximum calculated threshold.
