2017 Ram Promaster Window Van Check Engine Light Codes

Common check engine light codes for a 2017 Ram Promaster Window Van include P0420 (catalyst system efficiency), P0300 (random/multiple misfires), P0171/P0174 (lean fuel condition), and sensor codes like P0135 (O2 sensor heater circuit). Left unresolved, P0420 can damage the catalytic converter — a costly replacement — while misfires (P0300) can harm pistons and exhaust components and reduce towing capacity. Lean conditions can cause poor fuel economy and accelerate component wear, costing more in fuel and repairs over time. At Larry H. Miller Dodge RAM FIAT Tucson we map each code to clear repair options and costs, highlighting how timely, dealership-grade repairs produce immediate savings by restoring fuel efficiency and preventing secondary damage. Our certified technicians use OEM parts and factory diagnostics to avoid unnecessary part replacements and to keep long-term operating costs low.
