2015 Ram 1500 Check Engine Light Codes

At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, we routinely decode and repair the most common trouble codes for the 2015 Ram 1500. Typical codes include P0420 (catalytic converter efficiency), P0171/P0174 (lean conditions), P0300 (random misfires), P0455 (EVAP leak), and P0128 (coolant thermostat). Ignoring these codes can escalate costs quickly: a failing oxygen sensor or EVAP leak often lowers fuel economy and causes emissions failures; left unchecked, misfires can destroy a catalytic converter, turning a small repair into a thousand-dollar replacement. Our certified technicians use factory-grade diagnostic tools to identify root causes and present clear repair options, helping you weigh immediate costs against long-term savings. We use OEM parts and provide documented service so warranty claims remain intact. To make service convenient we offer online booking—schedule service—and rotating service specials that reduce your initial expense. Choosing our dealership for your 2015 Ram 1500 often yields faster turnarounds, transparent pricing, and preserved resale value compared with piecemeal repairs.
