I bought a 1996 jeep cherokee and the oil pressure has always been way high. Like 80 to past 80. After it warms up for a while it will drop to 40-60 when it idles but as soon as i give it gas it goes back to 80 and beyond. I think its the pressure sender but when I went out to find it based on what I have read Mine looks way different then everyone elses. Am I looking in the wrong place? Am I even fixing the right thing?

 

That's where mine is on my 2000. But looks different. Maybe aftermarket? Mine has a wire harness that just plugs it in I believe

 

I see what ya mean... I have a 96 and mine doesn't look anything like that. I would guess a previous owner rigged something up.

 

I'm dealing with oil sender unit problems right now too and that certainly is not OEM.

Lawd and that looks like a quickie oil change filter, no bueno!

 

So as far as replacing it, its missing the plug in like the oem requires so should I just leave it be? I would like to know at least a semi accurate reading of my oil pressure

 

I am changing the oil and filter on monday. The previous owner was more of a DIY guy then he let on clearly

 

You can always buy a new plug and splice it in. I screwed up the wire on my plug when I was wrenching on the oil filter last summer, and just spliced a new one in.

 

You can purchase the plugin as well, I was given that option when I ordered my unit from rockauto.
If you can get your hand on a mechanical oil pressure tester I would manually test it to see what it reads and compare that to what your rigged up sensor reads.
As far as replacing it, that's a personal choice if it works. If it doesn't work, then your choice is obvious.

 

Thanks guys. I will see if I can get it manually read. And then hopefully get that wiring harness ordered

 

Don't make a mountain out of a molehill. The oil sender only has one wire...and you can crimp on whatever fitting will sit on the new oil sender.

Buy a new one and spin it on....
