Are there any problems with the GM gauge clusters?

The next most common problem seen on GM instrument clusters are failing digital displays. This problem is unrelated to the stepper motor problem but is often seen in the same clusters. Most GM gauge clusters of this time frame have two digital displays – the odometer and the gear indicator (commonly called the PRNDL screen).

Why does my oil gauge read too high?

Oil Pressure Gauge Reading Too High. Another common oil pressure gauge problem is a reading that’s too high when your engine is idle or when it’s turned off. The gauge should never read very high when you’re not driving because the engine should be fairly cool due to inactivity.

Can a broken oil pressure sensor be a problem?
