DTC P0335: Crankshaft Position Sensor "A" Circuit [02/2014 - 11/2015]: Description

WARNING: This page is about a different variant/trim than selected.

The crankshaft position sensor system consists of a crank angle sensor plate (crankshaft) and a pickup coil. The crank angle sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed on the crankshaft.

The crankshaft position sensor generates 34 signals per crankshaft revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the fuel injection and ignition timing are controlled.

P0335	Crankshaft Position Sensor "A" Circuit	Either the following conditions is met (1 trip detection logic): No crankshaft position sensor signal to ECM while engine running. Missing crankshaft position sensor signal despite VVT sensor signal inputs normal after engine cranked.	Open or short in crankshaft position sensor circuit Crankshaft position sensor Crankshaft (crank angle sensor plate) ECM	Comes on	DTC stored

Fig 1: Identifying VV1, VV2 & NE Signal Waveforms

HINT:

The correct waveform is as shown.
VV1 and VV2 stand for the VVT sensor signal, and NE stands for the crankshaft position sensor signal.
Grounding failure of the shielded wire may cause a noisy waveform.
