The definition of this code is:
P1309 Engine Misfire Detection Monitor not enabled

It's a problem with the detection circuitry, not a detection of a engine misfire condition. I found this quickly on the net:
Diagnostic Trouble Code (DTC) P1309 indicates Misfire Detection Monitor is not enabled.

Breakout box installed, PCM disconnected. Connect digital multimeter between PCM test pin 85 and test pins 51 or 103. Bump engine in short burst with the starter without starting engine for at least 10 engine revolutions. Answer this question: Does digital multimeter reading switch between low (less than 2.0 volts DC) and high (greater than 8.0 volts DC)?

If Yes, Verify correct installation by referring to the Powertrain/Engine Group in the Workshop Manual. If the CMP is installed properly, REPLACE PCM. RESTORE vehicle. RERUN Quick Test.

If no, REPLACE CMP sensor. RESTORE vehicle. COMPLETE Misfire Monitor Repair Verification Drive Cycle. RERUN Quick Test.

The CMP sensor is the Camshaft Position Sensor.

    Hello and thanks for getting back to me, 1st off the car is 100% safe to drive. The next step is to have the dealer hook up what is called a "Flight Recorder", this will ID where the problem lies, the wiring or the PCM (Powertrain Control Module), you are over your head here, special dealer test equipment is required to find the cause of the Misfire monitor being disabled (code P1309)

P1309 ignition misfire


This should be a Ford engine - so according to the RangerStation website, the code is for the cam position synchronizer sensor is not installed correctly or not working. The sensor is telling the computer the cam timing is off.
You may need a book or internet search to test it and repair it.

Showing Code P1309. Replaced the cam sensor and still showing the code or CMP. What can it be?


You may need to replace the PCM, engine computer. very rare issue. Personally, I would leave it. It is only there to tell you if a cylinder is not firing. You will know if one is.

HD41 CHECK CMP SENSOR OUTPUT
  • Connect PCM.
  • Connect digital multimeter.
  • Start engine and vary engine RPM.
  • Measure voltage between CMP and PWR GND circuits at the PCM harness connector.
Does AC voltage vary greater than 0.1 volt AC? Yes No VERIFY the correct installation by referring to the Electronic Engine Controls, Section 303-14 in the Workshop Manual. If CMP is installed properly, REPLACE PCM (refer to Section 2 , Flash EEPROM). REPLACE CMP sensor. COMPLETE Misfire Monitor Repair Verification Drive Cycle.

----------------------------------------------------------------------------------------------
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.

My car have problen code P1309 plz help me


HI, The P1309 can be set due to a couple of problems the common being the CPS camshaft position sensor failed. There are other components that can cause this code to set including the ECT engine coolant temp, MAF mass air flow, CKP crank shaft position.There are no simple test that can be done at home but this code is usualy quick to diagnose for a good tech.

Engine light on with code P1309


This code could mean:
  • the camshaft position sensor could be defective,
  • the camshaft synchronizer (the part that took the place of the distributor on DIS engines) has failed,
  • if you have recently had the camshaft synchronizer replaced it could be out of time.
