Why would my check engine light come on after oil change?
Most likely, however, it is the oil sending unit. These often start leaking oil internally into the sending unit, which then gets oil in the plug in wiring harness, which causes the light to come on (or gauge to fail). These are relatively easy to check and/or replace on many vehicles.
Do you need to check the oil pressure in your car?
Typically, adding sufficient engine oil is all you need to get the job done if there are no further breakages. For starters, your vehicle is bound to have a warning light for its oil pressure. This is more commonly called as the Engine Oil Pressure Warning Light. Before proceeding with anything else, be sure to look at the warning light first.
Where is the oil pressure warning light on my car?
It’s an icon present in one the gauges depending on your vehicle. Universally, the engine oil pressure warning light symbol is an engine oil container icon. If you’re not familiar with how it looks like, then an easier comparison would be a gravy boat.
Why does the oil pressure light come on and off?
The oil pressure is actually the sensor that monitors the engine’s oil pressure, and its only job is to switch on or off the oil pressure light. These sensors are often made of plastic, and it happens that these sensors fail.

Why does my oil pressure sensor keep coming on?
Any time this light comes on, even if you know your sensor is bad already, you need to check it out. If the dipstick reads that the oil level is fine and the engine sounds like it’s running quietly and smoothly, then the light is probably just the result of a bad sensor.
What should I do if my check engine light comes on?
Keep in mind that the fault code that caused the light to turn on in the first place is stored in your car’s onboard computer, and you can retrieve it using a simple Bluetooth-powered device linked to an app to get a precise idea of what exactly is wrong under the hood. Doing this on your own will save you money.
