Question about 2002 Jeep Grand Cherokee
Your PCM (engine computer) senses a fault code with an engine management component. You will need a codes reader to retrieve the code. If you you do not have a code reader, go to a well supplied auto supply store like autozone, and they will read the codes and let you know what they are. This would be the first step any Tech would do before diagnostic testing begins.
