DTC Advanced Diagnostics: P0365
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
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 CAM line open
CMP sensor B CAM line short to ground
CMP sensor B VCC line open
CMP sensor B SG 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, 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.
