DTC Advanced Diagnostics: P0017 (3.0L Engine)
DTC P0017: CMP Sensor B Rear Bank (Bank 1) and CKP Sensor Correlation
General Description
The powertrain control module (PCM) determines the camshaft timing based on the pulse signals output from the crankshaft position sensor (CKP) sensor and the camshaft position (CMP) sensor B (bank 1). If the difference between the crankshaft position and the camshaft position is excessive, the PCM detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 10 seconds or more |
| DTC Type | Two drive cycles, MIL on |
Enable Conditions
| Condition | |
|---|---|
| Other | VTC base position learning is completed |
Malfunction Threshold
Crankshaft position - (minus) camshaft position is less than -12.9 deg., or more than 12.9 deg. for at least 10 seconds.
Possible Cause
- CKP sensor failure
- CMP sensor B (bank 1) failure
- VTC oil control solenoid valve B (bank 1) failure
- VTC actuator B (bank 1) failure
- Timing belt failure
Confirmation Procedure
Operating Condition
Start the engine. Hold the engine speed [Engine Speed] at 3, 000 rpm without load (in P or N) until the radiator fan comes on.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC, the freeze data, and the on-board snapshot are stored.
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.
