What is the most common reason why the red oil pressure light comes on while the engine is running?
Your oil pump is bad The oil pump in your engine works hard. When your engine is running, the pump must circulate oil to all the engine’s moving parts. If it wears out or fails, it won’t be able to provide proper oil pressure. When this happens, the oil pressure warning light will come on.
Why does oil light still on if new oil changes has been made?
If your oil light stays on even after changing your engine oil, you’re going to want to check the sensor first to rule out a malfunctioning sensor as the cause. The oil pump may not be circulating enough oil to keep the engine’s parts lubricated and functioning properly, which can in turn cause multiple engine issues.
Why is the oil pressure warning light still on?
If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.
When does the oil light come on and off?

Why is my oil pressure sensor not working?
For the sensor to function, it needs one or two wires going between the instrument cluster and the oil pressure sensor. The engine compartment becomes hot while you are driving, and there are constant vibrations. This can cause wirings to get a bad connection or actually fail and break off completely.
