the check engine light is on because there is an existing code in the computer. to reset it you need a code reader... plug the code reader into the port under the drivers side dash and turn the key on...don't crank the vehicle just turn on the key and when the code reader reads the code just erase all the existing codes and the check engine light will go off unless there is still an existing problem with the vehicle and then it will put another code on the computer causing the check engine light to come back on.
