Question Spurious oil light... how hard is it to change the sensor??

OK, I've been getting the spurious oil lamp warnings now and then the last year or two. But they are more frequent now! Oil level is fine, and it's being changed regularly...

Anyway I was wondering how hard it is to reach the sensor to change it out. I was able to change my cam position sensor quite easily from the top... but the oil sensor is in the back somewhere? Reachable from top, or is it an 'under-the-car' job?

It's located on the back of the engine block on the driver's side. You may be able to reach it from the top, but you will be working blind. It's a little easier from beneath the car.

This was one of the first things I did when fixing up the my PT Vert. Here's a link with some photos.

As Handy said, not bad from under. I did mine is about 10 minutes and I am super slow. Did it on ramps in my friend's driveway. Hardest part is not breaking the clip on the connector.

Yeah, they're not to bad to replace, I've replace the oil pressure switch on my daughter's Neon, similar set-up.

There's a red clip on the connector you may, or may not, be able to see. The clip probably need to be slid to the side to release the connector (picture from Rock Auto):


It looks like a 27mm (1-1/16"?) 6-point socket will fit the connectors, but there's also a special socket for these connectors. They use a kind of funky 12-sided drive. Here's the socket I got for the Neon:


Go for it.

I've done it twice, once in Jan & again in Feb.
I did it from the bottom the 1st time & from the top the 2nd.
It's much, much easier to do it from the top...JMO.

I didn't drain the oil the 1st time, small mistake...drained it the 2nd.

I replaced mine last summer. I removed the battery, tray and the bolts holding the fuse box bracket. IIRC it took about 30 minutes to change it. I did buy the special socket from Advance Auto for about $12..

Way back in the day, I had to change mine. It still worked, but it was spraying oil all over the exhaust and smoking. If yours is greasy, spray it down with some brake cleaner to remove the oil so you can get a grip and remove the connector. I did mine from the top, but I've got very long arms. Good luck!
