P0336 Crankshaft Position Sensor A Circuit Range/Performance

General Information

Component Location





General Description

A Crankshaft Position Sensor (CKPS) is a magnetic type sensor that generates voltage using a sensor and a target wheel mounted on the crankshaft; there are 58 slots in the target wheel where one is longer than the others. When the slot in the wheel aligns with the sensor, the sensor voltage output is low. When the metal (tooth) in the wheel aligns with the sensor, the sensor voltage output is high. During one crankshaft rotation there are 58 rectangular signals and one longer signal. The PCM calculates engine RPM by using the sensor's signal and controls the injection duration and the ignition timing. Using the signal differences caused by the longer slot, the PCM identifies which cylinder is at top dead center.

DTC Description

If frequency counter of the lost reference gap is over 2000, PCM sets DTC P0336.
