DTC Advanced Diagnostics: P0335
DTC P0335:Crankshaft Position (CKP) Sensor No Signal (Engine Type: J35Y1, J35Y2)

General Description

The crankshaft position (CKP) sensor detects injection/ignition timing for each cylinder and engine speed. The 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). If no pulsing signals from the CKP sensor are detected, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold
No input signals from the CKP sensor are detected while signals from the camshaft position (CMP) sensor are detected at least 125 times.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
CKP sensor CRK line open
CKP sensor CRK line short to ground
CKP sensor power supply line open
CKP sensor ground line open
CKP sensor failure
PCM internal circuit failure

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
