P0322 - Ignition/Distributor Engine Speed Input Circuit No Signal

P0322 - IGNITION/DISTRIBUTOR ENGINE SPEED INPUT CIRCUIT NO SIGNAL

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.
Possible Causes:	CKP+ circuit intermittent open (VR type) CKP- circuit open (VR type) CKP circuit open (Hall effect) VREF circuit open (Hall effect) SIGRTN circuit open (Hall effect) CKP+ circuit short to voltage (VR type) CKP- circuit short to voltage (VR type) CKP circuit short to voltage (Hall effect) VREF circuit short to voltage (Hall effect) SIGRTN circuit short to voltage (Hall effect) CKP+ circuit short to ground (VR type) CKP- circuit short to ground (VR type) CKP circuit short to ground (Hall effect) VREF circuit short to ground (Hall effect) SIGRTN circuit short to ground (Hall effect) 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.
