Gauges in Your Car Not Working? Try These Fixes

2020-10-07· When only one gauge or light stops working, the problem is either a bad sensor or a bad gauge. Diagnosing a single bad gauge or warning light requires you to locate the sensor that connects to it. Disconnecting the sensor is usually the first step. Depending on how the gauge works, disconnecting the sensor, or connecting it to ground, may allow ...
