DTC Advanced Diagnostics: P0335 (3.0L Engine)
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
| Execution | Continuous |
| Sequence | None |
| Duration | Depending on the driving condition |
| DTC Type | One drive cycle, MIL on |
Enable Conditions
| Condition | |
|---|---|
| State of the engine | Running |
Malfunction Threshold
No crankshaft pulse from the CKP sensor are detected while the camshaft pulse from the camshaft position (CMP) sensor are detected at least 4 times.
Possible Cause
- CKP sensor CRKP line open
- CKP sensor CRKP line short to power
- CKP sensor CRKP line short to ground
- CKP sensor VCC1 line open
- CKP sensor VCC1 line short to ground
- CKP sensor SG1 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, the freeze data, and the on-board snapshot 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, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
