DTC Advanced Diagnostics: P0369 (1.5L Engine)
DTC P0369: Camshaft Position (CMP) Sensor B Circuit Intermittent Interruption
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 abnormal amount of pulsing signals from CMP sensor B are detected, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
The PCM detects abnormal pulsing signals from CMP sensor B at least 60 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 electrical noise overlapped
- CMP sensor B rotor chipped
- 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.
