Oil Pressure...Guage? Sending Unit? Engine Problem?



So I notice this when I got to work this morning. Oil pressure has always been between 40 and 60. Maybe a little higher under hard acceleration. I do know I need an oil change, but it has only been about 5000 miles. I am usually really good about doing one about every 3000-4000 miles. Anyways, I'm thinking this might just be a faulty guage. When I turn the engine off, all the other guages zero out. The oil guage stays just like this.

Any Ideas?


Thanks in advance,

-X

Check your fluid levels.... then disconnect the wire at the sending unit, you either have a bad sending unit, or you have a short in the wire causing it to ground out, which will peg your guage out.

Will check fluids at lunchtime. But I do know that contrary to normal XJ functioning, mine loses ZERO oil between oil changes, No spots on the driveway.

I just found it strange the the needle remained pegged after the engine was shut off.

Thanks Jeff...

Did a little more research and found others with the same symptom which was resolved with a new sending unit.



I wish more people would be alot more specific in their thread titles. It makes it really hard to find what you are looking for when searching when the title is extremely vague or generic. This causes others to start new threads about issues that have already been beaten to death. Which causes other to get pissed about people not searching.



To Do List for Tomorrow:

1- Replace Oil Pressure Sending Unit

2- Oil Change w/ Larger Oil Filter

3- Replace Belts

4- Clean Throttle Body

Beware, a lot of people, myself included, often have OPSUs that are bad out of the box, so if it doesn't work don't forget it could still be the sending unit.

I did notice quite a few others having this problem. Is this a quality control issue? I don't understand why so many new units would be faulty from the manufacturer.
