What does the check gauge light mean on a 96 Chevy c1500?

On a 1996 Chevy C1500, the check gauge light (sometimes also called the "idiot lights") doesn't indicate a single specific problem. Instead, it's a warning that one or more of your vehicle's gauges are reading outside of their normal operating range.

You need to immediately check your gauges (speedometer, fuel gauge, oil pressure gauge, temperature gauge, etc.) to see which one is malfunctioning or indicating a problem. For example:

* Oil pressure gauge is low: This is a serious problem indicating potential engine damage. Pull over immediately and turn off the engine.

* Temperature gauge is high: This indicates your engine is overheating. Pull over safely and let the engine cool down before attempting to diagnose the cause.

* Fuel gauge is empty: You're running low on fuel.

* Battery light is on (sometimes included with this system): Indicates a problem with your charging system.

The check gauge light itself is not a diagnostic tool. It simply alerts you to check your gauges to identify the underlying issue. Ignoring it could lead to significant damage to your vehicle.
