Detection Condition

DTC P1309 indicates misfire detection monitor is disabled, usually due to input signal generated by Camshaft Position (CMP) sensor. CMP sensor is a magnetic transducer. It detects position of camshaft and identifies when piston No. 1 is on compression stroke. A signal is then sent to the PCM and used for synchronizing firing of sequential fuel injectors.
