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.

System Operation
Auto Start Stop
The
auto start stop system helps reduce fuel consumption and decrease
emissions by automatically shutting down the engine when the vehicle
stops and the engine is idling, usually within 1500 ms (1...

Inspection
Cratering - fatigue failure
Spot glazing - incorrect seating
Scratching - dirty engine oil
Base exposed - poor lubrication
Both edges worn - journal damaged
One edge worn - journal tapered or bearing not seated
