Question about 2003 Chevrolet Silverado 1500
I would first check your oil sensors. If the sensor is in working condition then there is a very high chance its your gauge.
This is unfortunately a known issue GM vehicles. I do want to let you know that we at The Electronics Guru LLC., offer a solution to repair your gauge/gauges for a QUARTER of the dealer's price! If you or anyone else you know has a defective gauge, I highly recommend looking at our website. www.UrGaugeRepairGuy.com Please don't hesitate to ask if you have anymore questions.

SOURCE: oil pressure gauge reads past 80
now unless there is a very loud knocking of the motor which would mean that the engine's top end was not getting any oil I would say that your oil guage is sprung and needs replacing. a high pressure rating would indicate a restriction in the oil flow pasdt the sending unit or a plugged oil filter. if the filter were plugged you would know it because your enging would run tight in no time at all. replace the guage itself... please rate this........thanks

could be one of two things, oil pressure switch (located on top of engine behind intake) or instrument panel cluster, if your vehicle has under 70,000 miles, it's covered under warrenty

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.
