DTC P0335 CRANKSHAFT POSITION (CKP) SENSOR CIRCUIT MALFUNCTION





WIRING DIAGRAM

CIRCUIT DESCRIPTION
The sensor consists of magnet and coil. It is mounted on oil pan with specified air gap between the sensor core end and crankshaft timing belt pulley tooth. As the crankshaft turns, AC voltage (pulse) is generated in the sensor. ECM detects the crank shaft revolution speed from the signal and uses it as one of the signals for misfire monitoring.





DETECTING CONDITION





Reference
Connect oscilloscope between terminals C20-3 (+) and C20-11 (-) of ECM connector connected to ECM and check CKP sensor signal.

DTC CONFIRMATION PROCEDURE
1) Clear DTC and crank engine for 2 sec.
2) Select "DTC" mode on scan tool and check DTC.











INSPECTION

NOTE: If starter circuit is open (i.e., start signal circuit is OK but starter fails to run), this DTC is stored in memory at starter switch ON, even though CKP sensor is in good condition.
When starter motor fails to run and this DTC appears, check starter circuit first.
