1. DTC Descriptor:
DTC P0335 Crankshaft Position Sensor Circuit No Signal
DTC P0336 Crankshaft Position Sensor Circuit Signal Interference
CKP sensor signals ECM current crankshaft speed and position. CKP sensor produces an alternating voltage with different amplitude
and frequency. Frequency depends on the crankshaft speed, the output AC voltage depends on the CKP. The CKP sensor works
in conjunction with a 58X reluctor wheel that is attached to the crankshaft. ECM calculates the ignition timing, injection timing, and
knock ignition timing based on CKP sensor and camshaft position sensor input signals. CKP sensor is also used to detect misfire
and tachometer display. ECM uses CAN network to send the engine speed signal to the instrument cluster.
CKP sensor signal is sent through CKP sensor harness connector EO26 terminals A, B to ECM harness connector No.EO01
terminals No.21 and 20.
