The oil pressure light on my wife's 2004 Neon has been going on randomly. From what I read, the sensor is pretty easy to remove with a 1-1/16 deep socket, but finding the bugger is my dilemma. I know it's on the back side of the engine but I'm not sure if this is it.
Any help would be appreciated.

 

If I remember right back side of the engine down under the exhaust manifold. My sensor had a plastic top and it was leaking oil. I did buy the special socket and got it out. Mine was still working but just leaking. Make sure and put some Teflon tape on the threads if it does not come with it already. Straight forward job.

 

If I remember, right side of the engine pertains to standing in front, is that correct? It sounds like I have to get to it from underneath the car.

 

That's an O2 sensor. It's kind of a pain to see, but you can reach it by going over the top of the engine. It's lined up with cylinder #4 IIRC.

 

Makes it much easier to get to if you pull the battery out. Has a lime green electrical connector if I remember correctly.

 

Aha, removing the battery makes a whole lot of sense. Thank you for the suggestion!
