P0302 Cylinder 2 Misfire Detected

Description and meaning of DTC p0302

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. Auto brands that experience this code may include but are not limited to VW, Chevrolet, Jeep, Dodge, Nissan, Honda, Ford, Toyota, Hyundai, etc. The reason for a code P0302 being stored in your OBD II vehicle is that the powertrain control module (PCM) has detected an individual cylinder misfire. A P0302 specifically applies to the number 2 cylinder. Consult a reliable vehicle information source for the location of the number 2 cylinder for the vehicle in question. This type of code may be caused by a fuel delivery problem, a large vacuum leak, an exhaust gas recirculation (EGR) malfunction, or mechanical engine failure, but is most often the result of an ignition system defect resulting in a low or no spark condition.
