DTC P0335: Crankshaft Position Sensor "A" Circuit; DTC P0339: Crankshaft Position Sensor "A" Circuit Intermittent [12/2013 - 11/2016]: Description
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.

HINT:
- The correct waveform is as shown.
- VV1+ and VV2+ stand for the VVT sensor (for intake camshaft) signal, and NE+ stands for the crankshaft position sensor signal.
- Grounding failure of the shielded wire may cause a noisy waveform.
