Why did my oil pressure gauge stop working?

Just so, how do I know if my oil pressure gauge is bad?

The best way to test if your sensor is bad is through the lights on the oil pressure gauge. If the low oil pressure warning light comes on when they engine's oil levels are normal and your engine is running smoothly and quietly, then you likely have a bad oil pressure sensor.

Secondly, why is my oil gauge going crazy? Low oil level could cause the gauge to intermittently drop out, perhaps on turns or acceleration. Also, it doesn't hurt to check for dilution or contamination. If color and thickness seem OK, we'll move on to the gauge. Vehicles that have an oil pressure gauge employ a sending unit, threaded into a port on the engine.

Moreover, is it OK to drive with a bad oil pressure sensor?

You could have a bad oil pump. On the other hand, if the level is between “add” and “full,” and then engine was running quietly, you could have a bad oil pressure sending unit, light switch, or oil pressure gauge. You will need to top up your oil, and again, you can safely drive home.

How do I test my oil pressure sensor?

How to Test an Oil Pressure Sensor

1. Insert the key into the ignition, and turn the key to the accessory setting. The engine should not be running.
2. Look at the oil gauge on the dashboard. Unplug the wire that is connected to the sending unit, if the gauge is at zero.
