Advanced Diagnostics - DTC P0335: Crankshaft Position (CKP) Sensor No Signal (A/T System)






General Description
The crankshaft position (CKP) sensor consists of a rotor and a semiconductor that detects rotor position. When the engine starts, the rotor turns and the magnetic flux in the semiconductor device changes. The changes of magnetic flux are converted into pulsing signals to the powertrain control module (PCM). The CKP sensor detects injection/ignition timing for each cylinder and engine speed. If no pulsing signals from the CKP sensor are detected, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold
No CKP sensor pulsing signals are detected at least 63 times.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, the D indicator blinks, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC
