Hi Sir or Madam, I am John Mc, a Ford dealer technician.
I hope I can help solve your problem quickly and accurately.


First you have to repair the condition that is causing the light. To find out what is causing the light you will need to have it scanned. Once scanned you can follow the trouble codes and repair the problem. Once it is repaired you can disconnect the battery for about 5 minutes and it will clear the check engine light.


If you have any more questions please feel free to ask, it's what I'm here for!


If this answer has been helpful please accept so I can receive payment. Feedback is very
