Cam Position Sensor

Now to tackle the "Check Engine" light problem.
When I had Nyghtshayd scanned the code was for the CPS...I will post a pic of what I think is the CPS. Its on the block next to the AC compressor. But
what do I need to do?

Thank you.
 
There are 2 sensors to be concerned with.

One is the CranK Sensor(CKS) and the other is the cam cosition censor more commonly known as the CID(Cylinder IDentification) sensor.

The CKS(crank sensor) is the one down by the AC compressor.

The CID sensor is behind the power steering reservoir.

What was the code?
 
I don't remeber the number but my electrical tech guy Tom, said it was the cam position error code. He asked me if the car drove well I said yes he said, "don't worry bout it then."
 
Most likely a cam position sensor error - the one behind the power steering reservoir. Could be an issue with the harness for the connector to the sensor - the wire breaks inside the harness right at the connector.

The car can start and will run with a bad cam sensor. But usually what eventually happens without warning is it will not start. You will have fuel pressure, you will have spark, but the cam position sensor malfunction causes the PCM either to not inject fuel or it may inject fuel at the wrong timing.
 
I think Im gonna replace the sensor or at least check it out because the wires aren't broken, or could it be broken inside the insulation?

Inquiring minds want to know.

What happens is internal of the harness connector. Each wire is crimped to a terminal inside the molded harness connector. The wire itself fatiques just outby of the crimp and eventually breaks severing the connection. It is usually an intermittent failure since the wire can still 'contact' the broken end at the terminal crimp. The same type of failure occurs on other harness connectors as well, most notably the alternator regulator harness connector.

In my experience, it is the "right angle" harness connectors that suffer this fate more. It appears most "straight" or "in-line" harness connectors do not exhibit this failure at near the frequency of the 'right angle' harness connectors.

Next time I find one of these, I think I'll cut it open and perform an autopsy.
 
I found a wire broken inside the insulation.
I'm trying to figure out how to fix this without destroying the harnest.
I'm gonna try cutting the harnest and using aligator clip leads (small ones) or maybe just solder the wire to the sensor.

Any other ideas anyone?
 
Thanks Driller, that's on my "ideas" list too.
I took the sensor out and cleaned it, that is when I noticed the spunginess of the wire.
This thing is absolutly ridiculous. Surely Ford could've made these better.
Thank God the engine is pretty good...(knocks on wood @170k miles)
