Oil Pressure Sender

Posted

Since I have had my truck, the stock oil pressure gauge has not worked. The people before me installed a mechanical oil pressure gauge on the pillar but I want to put my fuel pressure gauge there. Is there any way to test the oil pressure sender? I just want to make sure thats whats wrong. The gauge in the dash just sits at 40 psi any time the key is on. I also have the code p0522. I believe that is for the oil pressure being out of range or something. Thanks!!!

I read through the p0522 code article already, I was just wondering if anyone had a similar problem with their oil sensor before. I am pretty sure its just the sending unit but I dont wanna waste $80 if thats not whats wrong.

Just to double check, The connector for this sensor is right behind the ECM on the driver side of the engine, correct? Its a green connector? I know it should be a three wire plug, but if the location is correct, mine only has one wire going to it...

My grandpas 01 does the same thing, he has never messed with it because the sensor is so expensive.

The dealers quote for the sender on my 2000 was $250.:doh:I got mine from Genos and only paid $59 a year ago.

I think the one at Geno's went up to close to $90 this year. I was just doing some research over at the cummins forum and everyone was saying that the stock oil pressure gauge was more of just an idiot light. As long as the ECM see's more than like 6 psi, it just throws out a number on the gauge. I think I am probably just going to stick with a mechanical gauge. Has anyone else heard of this?

I paid about $90 at Cummins for a sender.

:shrug: Mine never failed yet 208K miles...

What kind of numbers is your mechanical gauge showing going down the road once your all warmed up? Just kind of curious for a "real number"

If its cold, it hovers around 75-80 psi. All warmed up it is usually around 40-50 psi.
