Detection Condition

WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.

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.
