Nissan Murano: Dtc/circuit Diagnosis / P0335 Ckp Sensor (pos)

DTC Description

DTC DETECTION LOGIC

1. The crankshaft position sensor (POS) signal is not detected by the ECM during the first few seconds of engine cranking.

2. The proper pulse signal from the crankshaft position sensor (POS) is not sent to ECM while the engine is running.

3. The crankshaft position sensor (POS) signal is not in the normal pattern during engine running.

POSSIBLE CAUSE

• Harness or connectors [CKP sensor (POS) circuit is open or shorted.]

• Crankshaft position sensor (POS)

• Signal plate

FAIL-SAFE

Not applicable

CHECK DTC PRIORITY

If DTC P0335 is displayed with another DTC P0643, first perform the trouble diagnosis for DTC P0643.
