My oil pressure gauge doesn't work, should I be concerned?

Asked by Oct 14, 2014 at 10:42 PM about the 2003 Chevrolet Silverado 1500

Question type: Maintenance & Repair

When my truck is off my gauge is at
40, and when it's on and running it's
past 80.
It runs fine and I'm always on top of
oil changes, but I don't know if I
should be concerned about an
underlying problem

Just get a new oil pressure sending unit.

I don't know about anyone else but I'd be freaking out if my oil pressure gauge didn't work properly, that does sound like the gauge is wacked. What does it read with just the key on? If it reads 0 with just the key on then it could be an oil pressure sender, if it reads more than 0 then disconnect the sender wire at the sender, the gauge should climb right off the scale, if it does this then ground the wire at the sender and the gauge should drop to 0 or below, if it don't replace the gauge. Of course you could always install a manual gauge.

Mark and tennis shoes are both right. I'd start with the sending unit. It could be the gauge in the cluster. The clusters from about 1999-2006 in all the GM trucks had multiple gauge/needle problems. I've replaced about 30 of them.
