Trouble code P1309: Misfire monitor hardware - CMP misaligned, CKP/CMP noise (static), PCM AICE chip (engine computer).

To expand on this definition for you - it basically means there is a problem with the hardware (Wires, Cam or Crank sensors or engine computer itself) which is involved in detecting a misfire.

The hardware problem could be a misaligned CMP (Camshaft Position sensor), or a problem with the CKP (Crankshaft Position sensor) or indeed the engine computer itself.

The problem with these trouble codes is that they are diagnostic pointers and not definitive in themselves. The problem will require more troubleshooting to determine exactly which of these hardware components is at fault. However it does narrow the problem down to one of these.

Hope this helps. Please do rate my answer. Many Thanks.

P1309 misfire code

Could be that the camshaft position sensor could be defective, or the camshaft synchronizer (the part that took the place of the distributor on DIS engines) is failing, or if you have recently had the camshaft synchronizer replaced it could be out of time....

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.

Engine code p1309 P/S advice on repair

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.

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.
