DTC Advanced Diagnostics: P0369
DTC P0369:Camshaft Position (CMP) Sensor B Circuit Intermittent Interruption

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 abnormal amount of pulsing signals from CMP sensor B are detected, the PCM detects a malfunction and stores a DTC.

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.
