2017 Ram Promaster Cargo Van Check Engine Light Reset

Resetting a check engine light on a 2017 Ram Promaster Cargo Van may seem simple, but a reset without proper diagnosis can mask underlying faults and lead to more expensive repairs. At Larry H. Miller Chrysler Jeep Dodge Ram Boise, we follow a strict process: read and record diagnostic trouble codes, perform targeted tests, repair with OEM parts if needed, and then clear codes only after confirming the issue is resolved. Our certified technicians document the diagnosis and provide a transparent estimate before any work begins, and we clearly explain warranty terms — warranty-covered repairs must be done at a certified dealer to keep coverage intact.

2017 Ram Promaster Cargo Van Check Engine Light Codes

Common check engine light codes for the 2017 Ram Promaster Cargo Van include P0420 (catalyst efficiency), P0300–P0306 (misfires), P0135/P0155 (oxygen sensor/heater), and P0171/P0174 (fuel trim lean). Ignoring these codes can lead to cascading failures: unresolved misfires damage catalytic converters (thousands in replacement cost), lean conditions can overheat valves and cause poor fuel economy, and faulty oxygen sensors increase emissions and reduce MPG — costing more at the pump over time. At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, we diagnose each code with OEM scanners and give clear repair-cost scenarios and timelines. Our service advisors highlight immediate and long-term savings of professional diagnosis and OEM repairs, and we offer service financing so you can get necessary work done now.
