Oil pressure gauge all the way up... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SkylineNXS · 05-24-2009, 04:35 AM

Hey guys, i swear i saw something like this like a week ago, and i cant find the thread, so sry for the repeat. I was drivin the truck home from work 2 days ago and noticed the oil pressure gauge was maxed out, not at 60, just all the way to the right, pointing horizontally to the left. I didn't see it happen so i don't kno what it did when it occurred. I was wondering what you guys think i should check first, the sender or the gauge? And how would i go about checking the sender anyway? Thanks...

yeah I think I remember that post your talking about. IIRC they said that to test if your gauge was working. unplug it from the sending unit and it should peg to the max. then plug it back in and it should be at near zero. if that worked then your gauge was working... I wonder if yours maybe got disconnected some how???

An addendum to this is to test it with the ignition on, but not running. I had this same problem one time and it turned out to be a bad ground. If your lead is plugged in and still does this, check your grounds. Start first at the 6 post ground block above the fusebox.

yea the weirdest thing happened today, i assume it was a bad ground as mentioned though, but the gauge started workin at the perfect time. Im tryin to sell the truck and a guy came to look at it and the gauge started workin right then, lol. Sold it too! Thanks for the help guys....
