2024 Jeep Wagoneer Check Engine Light Codes

Common codes for the 2024 Jeep Wagoneer include P0300 (random/multiple misfires), P0171 (system too lean), P0420 (catalyst system efficiency low), P0455/P0442 (EVAP large/small leak), and P0135/P0136 (oxygen sensor issues). Each code carries different risks and potential costs: ignoring a P0300 misfire can quickly harm the catalytic converter leading to several thousand dollars in repair, while persistent P0171 lean conditions reduce fuel economy and can lead to engine damage. A P0420 left unresolved may fail emissions tests and require catalytic replacement, an expensive outcome compared with timely sensor or exhaust repairs. At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, our certified technicians diagnose these codes with factory-grade tools, explain probable causes and cost-effective options, and prioritize repairs that deliver immediate savings and long-term reliability. We provide transparent estimates, honor warranty requirements, and offer service financing and rotating service specials to make proper repairs affordable.
