2015 Jeep Wrangler Check Engine Light Codes

The 2015 Jeep Wrangler commonly logs codes such as P0300 (random/multiple misfires), P0420 (catalyst system efficiency), P0171 (system too lean), P0456 (EVAP small leak), and oxygen sensor codes. Left unresolved, these codes can quickly escalate: unchecked misfires can ruin spark plugs and damage the catalytic converter (repairs that can run into the high hundreds or beyond), lean conditions cause poor fuel economy and increased engine wear, and EVAP leaks worsen emissions compliance and trigger persistent drivability issues. At Larry H. Miller Casa Chrysler Jeep in Albuquerque, our factory-trained technicians use OEM parts and Chrysler/Jeep diagnostic systems to pinpoint the root cause—saving you money over time by preventing repeat visits and costly downstream repairs. We provide upfront estimates, transparent explanations, and often better value than independent shops because our diagnostic accuracy reduces unnecessary part swaps. When you want reliable diagnostics and a clear plan, schedule service or review our current service specials to maximize savings.
