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 engine control module (ECM)/powertrain control module (PCM). The CMP sensor B detects the top dead center of each cylinder for fuel injection timing. If no CMP sensor B pulsing signals are detected, a malfunction is detected and a DTC is stored.

Enable Conditions







Malfunction Threshold
No input signals from the CMP sensor B are detected while signals from CKP sensor are detected for at least 300 times.

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the ECM/PCM memory.

Conditions for clearing the MIL
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs. The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
