Possible causes

– Faulty Camshaft Position Sensor
– Synchronize Assembly not properly installed.
– Verify the cam sensor is synchronized
– Faulty Powertrain Control Module (PCM)
– Verify input sensor parameters are correct

Tech notes

Replacing the Camshaft Position Sensor (CMP) usually takes care of the problem, but if the sensor is installed out of synchronization it will produce the P1309 code. If the CMP is installed properly, REPLACE Powertrain Control Module (PCM). RESTORE vehicle. RERUN Quick Test .

When is the code detected?

Powertrain Control Module (PCM) disabled the misfire monitor

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)

P1309 FORD Description

Misfire Monitor Disabled When the misfire monitor is disabled, usually due to the input signal generated by the camshaft position (CMP) sensor, by sensing the passage of teeth from the CMP wheel.
