DTC P0365

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

General Description

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

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 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 B TDC line open
CMP sensor B TDC 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.
