Have the car scanned for trouble codes. Many parts stores (autozone, advance, etc.) will do a free scan for you. Report the codes back to fixya

The check engine light (yellow light) comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system u will seldom feel the car engine run any different, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

The check engine light and the vcs light came on in the car and we are wondering if it is safe to drive until we can get it checked.


It is not desirable to have the car/engine running if the engine light has come up, So it is ideal that you seek help immediately at the nearest service center.
Please check the engine oil levels, if low top it up before the car is moved.

Service engine soon light


an oil change will not turn the light off, this light means a fault has occurred in the electronic engine/emission controls, the easiest thing to do is go to any Kragen or Autozone part store and have them run a trouble code test,it is free, then post the code(s) back here on Fixya.
