DTC P0335: Crankshaft Position Sensor A Circuit

P0335 - CRANKSHAFT POSITION SENSOR A CIRCUIT

Description:  The powertrain control module (PCM) continuously monitors this sensor for concerns. This DTC sets when the PCM detects that the crankshaft position (CKP) sensor signal is missing for greater than a calibrated number of camshaft revolutions.
Possible Causes: 
  • CKP circuit open or short to voltage
  • CKP circuit short to ground
  • VREF or SIGRTN circuit open
  • Damaged CKP sensor
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.
