Exclamation oil gauge reads zero

while driving my 2001 tj 2.5L for an hour on highway, my oil gauge just dives to zero and the check gauges lights comes on. this happened last week when just driveing around town dove to zero but went back to normal in a second, this happened 3 times that day. anyways so i pull over, turn off the engine and check oil level and its fine. also the temps are fine. so i start the engine and it seems fine, i let it idle and the temps are fine and seams to be running fine. i continue my way home with the readfing still at zero and check gauges light still on. got home finee and once again everything seams normal. so im thinking the sensor came loose from the pump? has anyone else had this problem? can anyone explain/ help me with this.

thanks in advance.

DO NOT DRIVE IT!!!!!! make sure its the gauge first if its the pump you'll be replacing more then the pump or the gauge.

If it'snow knocking then most likely it's the sending unit near the oil filter. I think 150% of them fail. Mine did.

Happens to my rig just about every time I drive a long distance and come to a sudden stop. Then as soon as I go in motion again everything goes back to normal. Been doing it for awhile and every thing seems fine. I dont have to extra cash to replace the sensors or whatever is wrong with it.

If it isn't the sending unit it's the instrument cluster-both common problems .

have you checked your oil to make sure it isnt low? the gauge isnt for amount, its for pressure. if you have a busted line, it would be leaking. probably a sending unit but be sure before driving.

oil has remained at the same level. but those were my thoughts lost oil therefor losing pressure. but thanks for all the responses they have helped me out. im going to the garage tomorrow to see if they can find something wrong with the gauge.

I'm with the Oil Pressure Sending Unit folks....might as well swap it out - they aren't expensive and aren't hard to replace. Its scary driving down the street and all of the sudden thinking your oil pressure is zero...

1st thing is check your sending unit (near distributor) it's hard to get to if you have A/C...
mine acted up for a while and now is reading good (go figure), so I didn't replace mine.

Just replace the oil pressure sender mounted next to the oil filter, that's a common failure. It happened to me late one night on a very remote desert road 50 miles from nowhere within a year of having bought my then-new '97 TJ and it scared the crap out of me. Replacing the sender is not much harder than replacing a spark plug and is a similar process.

My 98 does the same thing. If its not overheating and there is not some kind of horrible sound coming from under the hood, like everybody said its the sender or the guage. My 2005 Chevy does the same thing.

Have you recently had any engine work done? Once, I had my car worked on in some local shop and when I got it back, I had the same problem. The reason was because when they scraped the red silicone gasket maker off of some parts of the engine it somehow made its way to the oil pan and then clogged my oil pump. That could also be your problem... just a dirty clogged oil pump.

what is the job of the oil sender? what exactly does it do, and why would it fail?

It's an electrical gizmo (variable resistor to be precise) that bases its electrical resistance on the amount of engine oil pressure inside the port on the engine block that it is screwed into. As the sender's electrical resistance varies up and down from the oil pressure going up and down, it controls the oil pressure gauge by making it go up and down in step with the oil pressure.
