Circuit Description

Crankshaft position sensor is a pick-up coil located at front of engine, just above crankshaft pulley and uses a 34-tooth signal plate located on the crankshaft sprocket. ECM uses input signal from crankshaft position sensor to determine crankshaft angle and engine speed. DTC P0335 is set when ECM does not receive input signal from crankshaft position sensor with engine cranking or with engine speed more than 600 RPM. DTC P1335 is set when ECM does not receive input signal from crankshaft position sensor with engine speed of 1000 RPM or more. Possible causes are:

• Crankshaft position sensor circuit is open or shorted.
• Defective crankshaft position sensor.
• Defective signal plate on crankshaft sprocket.
• Defective ECM.
