Hook a DTC reader up to it and then report back with the codes.
And in case you didn't know, pretty much any Auto Zone or Advance Auto can/will read your codes for you. Write down the number and then post it here (Example: P0420) |
Advanced Auto Parts will be able to tell you your code and clear it for you if its nothing serious. When my IC coupler popped off my CEL for the MAF sensor came on and they cleared it.
