DTC Advanced Diagnostics: P0365
DTC P0365: Camshaft Position (CMP) Sensor Circuit No Signal
General Description
The camshaft position (CMP) sensor consists of a rotor and a semiconductor that detects rotor position. When the rotor turns after starting the engine, the changes of magnetic flux in the semiconductor are converted into pulsing signals to the powertrain control module (PCM). The CMP sensor detects the top dead center of each cylinder for fuel injection timing. If no CMP sensor pulsing signals are detected, the PCM detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 2 seconds or more (when the engine speed is 750 rpm) |
| DTC Type | One drive cycle, MIL on |
Enable Conditions
| Condition | |
|---|---|
| State of the engine | Running |
Malfunction Threshold
No input signals from the CMP sensor are detected while signals from the CKP sensor are detected at least 300 times.
Possible Cause
- CMP sensor TDC line open
- CMP sensor TDC line short to ground
- CMP sensor power supply line open
- CMP sensor ground line open
- CMP 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.
