Check engine light on. has dtc of p1309. what could it be? I replaced cam sensor but code is still there.

Hi there:

DTC P1309 - Misfire Monitor Disabled

Several possible causes there, check ans test...
- CMP (Camshaft Position) sensor connector is damaged (check pins for damage, and for moisture)
- CMP (Camshaft Position) sensor has failed
- CKP (Crankshaft Position), ECT (Engine Coolant Temperature) or MAF (Mass Air Flow) sensor may be out-of-calibration
- CKP (Crankshaft Position), ECT (Engine Coolant Temperature) or MAF (Mass Air Flow) sensor may have failed
- PCM (Powetrain Control Module) has failed.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

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.

Have the ignition wires and plugs been checked?

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.

Cam sensor code, its mainly a misfire code, the worst will be to replace the ECM its better that you replace the cam sensor first, that should solve the problem you have

P1309=check the cam positioning sensor to see if it is sync here is a link:

P1115= ECT here is a link:

Hope this helps Tim

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.

Diagnostic Trouble Code (DTC) P1309 indicates Misfire Detection Monitor is not enabled, replace the cmp sensor.

The cam sensor will NOT prevent the engine from starting...it will set a DTC if it is malfunctioning. Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem. SUGGESTION: Perhaps the problem isn't electrical... It could be fuel/pressure.

for which code you want for you car model given by you.

you have to specify you requirements totaly,
