Codep1309 1999 windstar

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.

Get an older car with less computers running it. Sorry I can't be of any real help. I just wanted to a bit smart-elec.

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

Code PO1309 : Misfire Monitor Failure Description : When the misfire monitor is disabled,usually due to the input signal generated by the camshaft position sensor, by sensing the passage of teeth from the camshaft position wheel. Possible Causes : PCM(power train control module), Mass Air Flow Sensor, Engine Coolant Temperature Sensor, Crank Shaft Position Sensor, Camshaft Position Sensor.

P1309--Misfire Monitor Disabled

When the misfire monitor is disabled,usually due to the input signal generated
by the camshaft position sensor

Possible Cause---

Cam Position Sensor
Powertrain Control Module
ETC,MAF,CKP

Verify CMP is installed correctly


You need a local repair shop to check it out

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

Check the Camshaft position sensor it may be dead or out of sync

Look at the coil pack, these are known to develop cracks, usually on the underside in the resin, you have to remove it to tell. It is much easier to reomve with the wiper cowl removed.
