Miller Chrysler Jeep Dodge Ram Boise we re-set codes only after pinpointing and repairing the root cause, ensuring long-term reliability. Our process includes a comprehensive scan with OEM tools, a clear estimate, and a repair plan using factory parts and factory-approved procedures. This transparency protects your vehicle and can reduce lifetime maintenance costs. Warranty-covered repairs must be performed at a certified dealership; we manage warranty claims and use genuine components to protect coverage. We also provide service financing to help you address needed repairs immediately and avoid escalation.

2025 Ram 3500 Check Engine Light Codes

Common diagnostic trouble codes for a 2025 Ram 3500 include P0300 series misfire codes, P0420 catalyst efficiency codes, P0171/P0174 fuel trim codes, and various oxygen or mass airflow sensor codes. Left unattended, P0300 (random/multiple misfires) can damage pistons and catalytic converters — repair costs can escalate from a simple ignition tune-up to thousands for converter and engine repairs. A P0420 (catalyst low efficiency) often starts with sensor replacement but can lead to full catalytic converter replacement if untreated. Fuel trim codes (P0171/P0174) signal air/fuel imbalance that, when ignored, reduces fuel economy and accelerates wear. At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, our certified team prioritizes accurate code interpretation, clear cost estimates, and efficient repairs to prevent those escalating costs. We emphasize immediate and long-term savings: precise diagnostics avoid unnecessary parts, OEM components maintain performance, and expert repairs extend engine life.
