Driving home yesterday my temperature gauge on the 2003 Chevy silverado went all the way to the right as if it was overheating. No overheat light came on. I pulled over and checked everything and nothing was hot and it had water. So it wasn't actually overheating but the temperature gauge was all the way to the right as if it was overheating. After getting home I let the truck sit awhile and restarted it and the gauge didn't reset. What causes this and how can I fix it? Thanks for your time! Also reset it by disconnecting battery it was good for two days after turning key off and on the needle keep going higher and higher. Can you help I changed sending unit no luck now what?
What else can I help you with?

You may have a faulty oil pressure sending unit. remove the sensor and hook a pressure gauge up to it and get the gauge in a position the you can see it while driving. Get it up on the thruway and see if it is in spec. If you don't address this asap, there is potential to wipe out the motor.
