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.
