DTC P0335 - Crankshaft Position Sensor A Circuit
P0335 - CRANKSHAFT POSITION SENSOR A CIRCUIT
| Description: |
This DTC sets when the crankshaft position (CKP) sensor profile ignition pickup (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. |
| Possible Causes: |
- CKP+ circuit intermittent open (VR type)
- CKP- circuit open (VR type)
- CKP circuit open (Hall effect type)
- VREF circuit open (Hall effect type)
- SIGRTN circuit open (Hall effect type)
- CKP+ circuit short to voltage (VR type)
- CKP- circuit short to voltage (VR type)
- CKP circuit short to voltage (Hall effect type)
- VREF circuit short to voltage (Hall effect type)
- SIGRTN circuit short to voltage (Hall effect type)
- CKP+ circuit short to ground (VR type)
- CKP- circuit short to ground (VR type)
- CKP circuit short to ground (Hall effect type)
- VREF circuit short to ground (Hall effect type)
- SIGRTN circuit short to ground (Hall effect type)
- Damaged CKP sensor
- CKP sensor incorrectly installed
- Incorrect, damaged or corroded connections
|
| Diagnostic Aids: |
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. |
