DTC P0335
DTC P0335: Crankshaft Position (CKP) Sensor No Signal
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.
Monitor Execution, Sequence, Duration, DTC Type, OBD Status
| Execution | Continuous |
| Sequence | None |
| Duration | 2 seconds or more (when the engine speed is 750 rpm) |
| DTC Type | One drive cycle, MIL on |
| OBD Status | PASSED/FAILED/NOT COMPLETED (STILL TESTING) |
Enable Conditions
| Condition | |
|---|---|
| State of the engine | Running |
| No active DTCs set (prevents monitor from running) | P0339, P0365, P0369 |
Malfunction Threshold
No input signals from the CKP sensor are detected while signals from the CMP sensor are detected for at least 75 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 CRANK line open
- CKP sensor CRANK line short to ground
- CKP sensor power supply line open
- CKP sensor LG (GND2) 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 12 volt battery.
