It could be the sensor. It could be the screen under the sensor needs cleaning. It could be too low on oil. It could be the engine is worn out. You don't say the age of the engine or the mileage on it.

The real question is if the proper maintenance was done at the correct times. Oil and filter changes are super important and need to be done at the proper intervals.

Did you run a diagnostic scan to see why the CEL is on?
