Crank and camshaft position sensors

Four cylinder two wheel drive automatic 135,000 miles.

Hello,

My car (2.2 liter) has a bad crankshaft position sensor. The only problem I have is that I do not know where it is located on my car. I have searched and cannot find it. Is there a diagram of some sort that I can look at or is there a detailed explanation somewhere where I can find the sensor location on my car? I have the same issue with the camshaft position sensor.

Do you
have the same problem?

I need to replace the pigtail to the camshaft sensor. Where are the wires located that I would splice the pigtail to?

How do you know? If problem is ref voltage--ground or signal, you need to find out.

The electrical connector comes apart, you may be able to use needle-nose pliars to squeeze contacts. The partsbook I looked at shows only connector, no pig tail wires. If you have a connector with pigtail wires just splice them in.

The wires on the cam shaft sensor connector have been chewed by a mouse. I have the wire connector that connects to the cam shaft sensor. I just need to know where the wires to splice to the new connector are located and how would I locate them?

I've never seen that happen with a vehicle regularly driven, them varmints don't like that hot engine.

I can give wiring colors below, the wires go to the pcm. That's about all I can do, check the wiring harness for the proper wire colors. The info was for 2.2L engine.

Where is the pcm located? The car sat for a few months in farmland, and the mouse had a field day with the wires, literally.

Sounds like a nightmare. The pcm should be right front of engine compart, passenger side. At the moment, I don't have a picture.

Is it easily accessable? Also I noticed several wires connected to a believe a relay right under the air filter. Could that be the pcm?

I don't know, I would have to look? Sounds like your in over your head, no offense intended.

You have to safely raise and support the vehicle, passenger side. Remove engine splash guard, to get at pcm. As far any other wiring, I'd have to look at it. You need a friend or somebody that knows about vehicles, that can actually look under the hood. I can't see anything from here.

I was informed that the cam sensor is controlled by the ecm and I would find the wires at the ecm. Problem is my buddy isn't able to make it to my place today to locate the ecm. Any idea where it would be and how would I access it?

The starter cranks good, starts up good, and seems to run fine. I replaced the plugs and wires and the valve cover gasket and changed the oil.
