Advanced Diagnostics - DTC P0365: Camshaft Position (CMP) Sensor B Circuit No Signal (Engine Type: K24Z7)

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). CMP sensor B detects the top dead center of each cylinder for fuel injection timing. If no CMP sensor B pulsing signals are detected, the ECM detects a malfunction and stores a DTC.

Possible Cause

NOTE: 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 TDC line open
- CMP sensor B TDC line short to ground
- CMP sensor B power supply line open
- CMP sensor B ground line open
- CMP sensor B failure
- ECM 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 ECM 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 battery.
