Check Engine Light on After Oil Change [Causes and Solutions] • Road Sumo

1. Dipstick Not Properly Reinstalled

If you performed the oil change on your own, it is likely that you did not place the dipstick in the correct position. In this case, the check engine light may come on because the dipstick isn’t properly seated.

2. Oil Reservoir Cap Concerns

You must turn the reservoir’s cap clockwise once you’ve added additional oil to the tank. Having an oil cap that is either cracked or installed backwards could be causing the check engine light to remain illuminated.

3. The Reservoir is Overfull

Running an engine with low oil is bad for it, but running an engine with an overfilled oil reservoir is equally bad for it. While re-filling new oil, it’s best to use a dipstick to check for the proper amount of oil. If the oil reservoir is overflowing, you must drain it.

4. Something Else Is Wrong

Even if you make sure the oil level in your reservoir is correct, the dipstick is properly installed, and the oil lid is secure, the check engine light will remain illuminated. Something else may need to be taken care of. Check your car for problems, look up the trouble codes, and replace any damaged or malfunctioning parts..
