DTC Advanced Diagnostics: P0365 (1.5L Engine)
DTC P0365: Camshaft Position (CMP) Sensor B Circuit No Signal
General Description
Camshaft position (CMP) sensor B 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 PCM determines exhaust camshaft timing position according to the pulsing signals from CMP sensor B and the crankshaft position (CKP) sensor. If no CMP sensor B 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 CMP sensor B are detected while signals from the CKP sensor are detected at least 50 times.
Possible Cause
The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- CMP sensor B CAM_EX line open
- CMP sensor B CAM_EX line short to ground
- CMP sensor B VCC1 line open
- CMP sensor B SG1 line open
- CMP sensor B 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.
