2012 jeep wrangler oil pressure sensor

It’s a little intimidating but not a technically difficult job to do.

Recently helped a fellow forum member with it, and it was good doing this as a team. It did take all day (taking our time and not rushing)

The oil temp sensor is located next to the pressure sensor.

One option is to proactively replace the oil cooler with the more reliable 2014+ model; it comes with new oil sensors already mounted.

If your spark plugs are anywhere near their time for replacement, do that at the same time.

Don’t go to a dealership, they’ll rob you blind. Get a quote from a reputable independent shop if you don’t want to tackle it yourself.

I was the forum member this post refers to, and I am in agreement, its not difficult, we took all day mainly because we wanted to take pictures and be sure we didn't miss something as we replaced old parts with new, also wanted to be sure we didn't accidentally break clips or any thing like that.

It is not difficult, and having all your tools plus some sort of suction pump is a good idea. I would suggest doing it your self but can understand if you would rather pay someone to do it for you, but please by all means DO NOT go to the stealership they will take you for a ride with out lube.

I would also recommend getting the 2014+ updated design and swap it in, it is a direct bolt in and I have more pictures in my build thread, same sensors also, so your basically going to correct two (possibly more?) issues at once by doing the upgrade. (see picture)

issue 1: your immediate problem of the failed sensor.

issue 2: possible failure of the other sensor also located on the oil cooler

issue 3: potential failure of the stupidly designed spring loaded return valve (its really a matter of when not if on this little guy)

so for the price that I paid ($105.99) I felt that it was worth it to replace all three items at once especially as I do not want to have to go back in again if I don't need to for a good long time. I would also suggest changing your spark plugs even if they may or may not need to be changed (exception is if you have less then 20k on the current ones IMO) and possibly the coils also. as you will have access to those as well (much easier access), another item would be the PCV valve, if you have lots of oil getting into your intake may be worth considering the PCV valve replacement.

and for the final bit of info, yes while your intake pieces are off I would also hit the upper and lower gaskets, even IF your current gaskets are still good looking, why take the risk? they are already exposed might as well change them.

parts I used for this adventure?

6 pack of Accel coils $138.91 (I got these as I was already pulling the old original coils off and figured it would be good to replace)
Spark plugs $47.94 (I went with NGK Iridium 4's)
M0-349 Mopar Oil Filter $8.60 (THIS IS THE UPDATED DESIGN FOR THE 2014+ JEEPS)
5qt of 5w-30 synthetic oil 56.43
Fel-pro MS97204 set $31.80
2014+ oilfilter housing $105.99

now I went and did a bit more then just change the oil cooler, I also changed my oil as I was already going to loose oil by removing the oil cooler, I figured the less mess the better so changing your oil would be a good idea, not required here, but at the minimum have at least two quarts handy just to replace what you loose, also grab a gallon of coolant (make sure you use what ever is CURRENTLY in YOUR jeep, I am currently filled with Green so that is what I used to top off.
