P0335 Crankshaft Position Sensor 'A' Circuit

General Information

Component Location





General Description

The Crankshaft Position Sensor (CKPS) is a magnetic field sensitive 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. 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

Checking reference signals from CKPS under detecting condition, if any signal is detected for more than 0.15 sec., PCM sets P0335.
