" P1309 - 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. Camshaft position sensor
Powertrain control module
ECT, MAF, and CKP sensors
Verify the CMP is installed correctly and not out of synchronization.&Quot;

Right out of the book.

Camshaft position sensors require a special tool for proper installation, One I would go to a pro for.

Good luck and let us know. : )
