Q: Service Engine Soon light on

asked by on December 15, 2016

My service engine soon light is on and I need to find out the problem so I can get it inspected. There are no problems going on...it starts runs and drives fine. Maybe oxygen or other sensor? Gas cap seems fine. Thank you

My car has a manual transmission.

Your check engine light being on is an indication the computer has seen a problem in its systems and set a code. the code will need to be retrieved with a scanner and then a pinpoint test done to find the cause of the code. You may have O2 sensor codes or evaporative emission leak codes. The code will need to be retrieved first. Have a mechanic like one from YourMechanic come and do the tests for you.
