what pressure is it reading, what engine do you have? the acceptable PSI level for a V8 is anywhere between 7-80psi

My engine is 4.0 straight 6. The oil pressure reads between 0-10. Sometimes the gauge light comes on

Where is the best place to buy a sensor? People reccomending Mopar but seems to be probs with their sensors. I've been throwing a 0523 code and occasionally my gauge reads no pressure.

Thanks guys.

My replacement oil pressure sending unit sheared off as I was tightening, so I have the threaded "nub" still in the engine block with the rest of the sensor not connected. From underneath I can feel that some of the threads are exposed so I may be able to use a vise grip to twist it out. However, access from below is really tight. Does anyone know if there's a way to access from the top? Possibly by removing the airbox?

When I bought my 2000, it did exactly the same thing.....pressure on the gas, nothing at idle, with accompanying chime tone and warning light. So I got a sender off of RockAuto, and my problem turned upside down, hahahah.

Now I have no pressure when I hit the gas, and great pressure at idle. I have a replacement sender to install.

I'll gladly report back with my pressure readings when I get a sender in it that works, LOL
