DTC P0365

DTC P0365:  Camshaft Position (CMP) Sensor Circuit No Signal

General Description 

Courtesy of HONDA, U.S.A., INC.

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

Monitor Execution, Sequence, Duration, DTC Type, OBD Status 

Execution	Continuous
Sequence	None
Duration	2 seconds or more (when the engine speed is 750 rpm)
DTC Type	One drive cycle, MIL on
OBD Status	PASSED/FAILED/NOT COMPLETED (STILL TESTING)

Enable Conditions 

Condition
State of the engine	Running
No active DTCs set (prevents monitor from running)	P0335, P0339, P0369

Malfunction Threshold 

No input signals from CMP sensor are detected while signals from the CKP sensor are detected at least 300 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 TDC line open
• CMP sensor TDC line short to ground
• CMP sensor power supply line open
• CMP sensor LG (GND2) line open
• CMP sensor 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.
