The oil pressure sensor is located toward the back of the engine to the passengers side of the distributor. There's a 2 prong wiring harness plugged into it and you'll need a very deep socket to get it out (I can't remember the size)

 

It's easier to actually break off the plastic part so you can use a regular socket to get it out because a deep socket wont work, you need that special one shown.

 

LOL! Your forgetting one thing... you still need to get the new one on in one peice! And you don't need Dodge's special tool, you just need a deep socket. I replaced mine with a deep socket I had in the garage... I didn't even have to go out and get one.

 

Ya I was able to use the deep socket that I have. Eazy to use. What some people have done is make a tube to relocate the sensor up. Chevy engines usually come with something like that. It's just an extension tube. Then you can put it where it's easy to get channel locks on it or what ever you want.

 

So Do I have to buy a new sensor or is it just loose or something?

 

Well, if you think it may just be loose, get under the hood and see if it turns by hand. Also, make sure the connector is pressed all the way down. If it's not loose, I'd say replace it... they aren't too expensive.

 

No I don't No more inferior factory gauge crap.

 

WOW, look at the size of the cables going into those gauges.

 

What you see there is just a wire wrap called convoluted tubing. The wire itself that is inside it looks to be just a simple 16-18 gauge wire.
