Hello and Welcome to Justanswer, My name is XXXXX XXXXX X am here to try and assist your with your question.The check engine light comes on when the PCM (computer) sees a system fault and many things can cause this . When the light comes on, it will set and store a fault code and or codes. In order to know what the problem is you need to have the system scanned and the code retrieved. Once you have them, we can direct you int he correct repair . Most part stores will run the scan for you at no charge. If the light wasnt on before the repair its very likely something you may have knock off or left loose.
