Causes of oil light flickering when braking
If you have a car, then you probably know what it feels like for the oil light to start flickering the moment you touch the brake. The orange light comes on the dashboard and starts flickering.
The only way to know what the reason why the oil light is flickering while braking is to run a complete diagnosis on the car. However, the light might be triggered by any of these:
- Bad oil pump: The oil pump is responsible for carrying the oil into the engine. The pump will not be able to produce the required pressure if the oil is leaking. When this happens, the light on the dashboard will start flickering. You can solve this by replacing the oil pump immediately.
- Faulty oil pressure sensor: Another reason why the oil light might be flickering while braking is if the pressure sensor is damaged. The sensor is the component that tracks the pressure of oil in the vehicle. It then sends the information back to the instrumental panel.
So, if the information being sent back is far from the acceptable range, the light begins to flicker. This is a minor problem but it needs to be fixed as fast as possible.
- Oil Leaks: Oil leak is yet another common reason why your sensor light might come on and keep making that flicking sign. If the oil in the vehicle is leaking, the amount of oil needed for the full function of the vehicle will lesser.
This means other components which it needs to lubricate will not get the needed oil. This will lead to friction among those components and then trigger the indicator light.
