P0335 - CRANKSHAFT POSITION SENSOR A CIRCUIT
| Description: | The powertrain control module (PCM) monitors the crankshaft position (CKP), camshaft position (CMP) and injection control pressure (ICP) signals during engine cranking. The DTC is set when the CKP signal is inactive while the CMP and ICP signals indicate the engine is rotating. The PCM also monitors the CKP signal for electrical noise. When the electrical noise exceeds the calibrated threshold the DTC sets. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | An inactive CKP signal causes a no start condition. Monitor the RPM PID while cranking engine. A 0 RPM indicates a CKP concern. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
