LLY: Check Oil Level $#!+

[9mmTeacher]

I have an 05 lly that gave me an oil pressure low on dic and lost oil pressure gauge simultaneously on start up. I checked oil, level good, and restarted with same result. Figured sensor bad, talked to gm folks, they thought same. Changed pressure sending unit, no low pressure message but still no gauge pressure. Measured pressure remotely, good. Changed oil and filter. Still no gauge but get a check oil level message on dic on every startup. Confused. Wife's car recently had some wire damage due to rodents. I can't find any damage. Will change out stepper motor, but gauge motor was replaced a couple of years ago. Any ideas what to do or where to look?

If the DIC is displaying check oil level, the ECU is not seeing the low oil sensor. Look for wire damage under the hood. If you take the fuse box apart, the wires underneath tend to get eaten by rodents. I'd look there first.

I would start by hooking up a mech. gauge and making sure you have oil pressure and go from there. Better safe than sorry......really sorry

Under the box holding all the relays etc? Thanks, I'll look there. There were some acorn leavings on top of the big wire bales. Didn't see a my damage or bite marks there.
