Baystate Jeepers

so when i first start my jeep more than half the time it records zero oil pressure, and doesn't go up at all. eventually the check gauges flashes and beeps at me. instead, if i start the jeep, turn it off immediately, then start it right back up it works normally. today i got a "low oil pressure" code (P0522). oil pressure looked fine while i was driving, in the normal range. any thoughts on why this is happening?

I would say you have a loose wire to the oil pressure sending unit, or a bad sending unit.

thanks guys, i'll take a look at the wiring tonight. i'm assuming this is what i might need? http://www.quadratec.com/products/2242.htm

Should be like this...

$9.77 from Rockauto.com
$19.99 at Advanced Auto
$22.99 from Autozone

gotcha. i don't think i'd trust an autozone unit, but maybe napa carries it. though advanced isn't bad.

Or you can try a dealer. The dealer part number is: 04868672AA

For the price the stealership wants I bet you could buy a few discount auto ones....

Thats so weird , My Sportrac does it only in the winter or when its like 40 or colder. The first time I freaked. No engine noises and I put a mechanical gauge to make sure. Still does it now even with a new sensor. ? Whats next? FjR68

When I replaced mine I got one from Crown Automotive (via Lou)... Wasn't too expensive. Doesn't read quite the same as the stock one, but it works...

"T" in a mechanical gauge. I never trust the factory sending units. Just make sure you get a good one that uses copper line.

my jeep will do that if i have it on acc for a minute then start the jeep but about a mile down the road it fixes itself

$15 at the dealer and 10 minutes of wrenching later the issue is gone. FYI, for some reason they needed the VIN # so it may be very specific. not that the guys at most dealerships are all that good, but i'm glad i went there versus autozone. i never would have gotten the right part.
