2003 Ford Taurus engine code 336

I need the actual code to help there is no 336 code. On an obd2 computer they are all 4 digit codes and even P0336 isn't found. So get back to me on the code so I can help you.

First sorry you feel I didn't get back to you I do not work on Sunday's as that is Family day for me. As for the code it could be either the cam or crank sensor or even the Power Control Module. I need to know if you have a Digital Multi Meter and how many wire cam sensor you have? If you want to test the sensor to see if it is bad and have a meter to test with then get back to me with the needed info and I will give you test to the type of cam sensor you have and we will go from there ok.

Ok now if the sensors are off in gap or anything that may change the expected reading of them it will also set that code. What I am saying is that the computer is set with what the sensors should be reading and if between the two they do not agree with what the computer know's to be right then the code is back. So lets see if it is a sensor or the PCM let not just jump to it I don't sell that many at work. So with that you need to use you Digital Multi Meter and measure voltage. you need to disconnect the harness to it and with the key on engine off check voltage between the harness and the neg side of the battery if it is 10.5 volts or better then you will do the next step, which is to turn key off and check for voltage between the connector and the pos. side of battery if 10.5 volts or better then let me know and we will go to the next step. What we are testing is weather or not there is an open circuit. So here is the plug diagram so you know what is poss. or neg on the plug.
The first step is checking that the sensor is getting voltage so you do it on the batt side of the connector the second is checking the ground side, does this make sense? here is the diag op the plug

Ok with the key on engine off you are only getting 1.3 volts need to be 10.5 there is a problem.
Now with key off diconnect the pcm connector make sure the cam possition sensor it pluged in good and between cam sensor and power ground circuit at the pcm connector set volts to 20 dc crank engine over at least 10 revolutions (engine will not start) voltage should switch from 2 to 8 volts if so pcm is bad it not then you got a bad sensor. So possitive from multi meter goes to term. 85 and the ground to term 103. Here is a pic of the connector and how the terms are numbered.

First you told me it was code p1336 not 1136 and yes check the cam sensor they work together as for the pcm connector it is on the right rear corner of the engine compartment mounted on the firewall.

Ok if you have no voltage then there is a short on between the sensor and the pcm. So what needs to be done now is measure resistance at the cam sensor. Plug the pcm harness back in and unplug the cam sensor harness and measure the resistance of the harness itself in pic below. If resistance is more then 500 ohms then we will test the sensor itself if it is less then 500 ohms then the pcm is bad and you will need to replace it. Get back to me with what you find ok.

Just letting you know before racefan966 gets back to you ! You will need to check the sensor with key ON engine off you will get no resitance with key OFF engine OFF try the test again and racefan966 will get back to you

Iv'e been going over your post's and need to clarify a point untill racefan gets back to you?

I checked the voltage at the terminal of the camshaft position sensor with both the key on--engine off also key on engine running and key off and the voltage is 0.00 in every situation. I have already sent you the voltage readings on the crankshaft position sensor.

Was the PCM harness plugged in when you tried this test? The reason I am asking is in the next post it say's plug the harnes back in?
