Camshaft Position Sensor Location and Replacement?

That is likely the problem. Let me know if it takes care of the issues. Darn mice! You have no idea how many times they have caused problems.

Take care,
Joe

Good morning,

This is a complicated code as there are so many possibilities.

It could be anything from a bad timing chain to a bad guide or phaser, a clogged oil control valve from sludge in the oil to a electrical issue.

The diagnostic tree is below and you will need an advanced scan tool to monitor the system.

The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

Good afternoon,

Is it the intake or exhaust cam sensor? There is one for each.

Why are you replacing it? They are not common failures. Do you have a code? If you do, can you give me the code so I can help you track down the failure?

Roy

340 possibilities. I listed the possibilities below. It looks more electrical than a sensor.

If you have a scan tool, you can monitor the cam sensor readings while the engine is running to see if there is a signal being sent to the PCM.

I attached the location of the CMP sensors. Let us know if you still can't find them and we will see if we can get some more info. Thanks

The repair manual gives instructions to remove the transfer case, but I have done this from the top side. I pulled up a view with the valve cover off because there are no clear illustrations that show this, backside of the driver side head. One 8mm bolt holds each sensor in, so a shallow 1/4 drive 8mm socket and ratchet should get it done.

You are welcome!

Hello, I'm Danny.

That sensor will be located on the right side (passenger) cylinder on the back of the cylinder head at the bottom. Here is a tutorial showing how to replace:

I've attached pictures below, However this is the left side. Similar picture but yours will be on the opposite site.Circled in red.Hope this helps and thanks for using 2CarPros.

Can you be more specific on which engine? You have 5 options but more than likely you have a 5.0L so I attached the info on these sensors.

Plus, here is a guide that will help with this that has some good info:
