Check Engine Light Reset

Resetting the check engine light on a 2026 ram promaster-cargo-van can be done with an OBD-II scanner, but a simple reset does not resolve underlying faults. At Larry H. Miller Dodge RAM FIAT Tucson in Tucson, AZ, our technicians perform a full diagnosis before any reset to ensure permanent fixes rather than temporary fixes that mask symptoms. When you bring your vehicle to the dealership, you get factory-trained technicians, OEM parts, and clear documentation of repairs—essential factors for preserving warranty coverage and long-term value. Transparency is central: we provide written estimates, explain the consequences of deferred repairs, and outline immediate and long-term savings from correct repairs—better fuel economy, reduced emissions, and fewer repeat visits. We also offer service financing to help you address necessary repairs now and spread payments over time. Before any reset, you’ll receive a full code readout and an explanation of recommended repairs, and we’ll only clear codes after confirming that faults are fixed.

2026 ram promaster-cargo-van Check Engine Light Codes

Common codes for a 2026 ram promaster-cargo-van often include oxygen sensor faults (P0130–P0167), EVAP system leaks (P0440–P0456), misfires (P0300–P0308), and catalytic converter efficiency issues (P0420). Left unresolved, oxygen sensor failures increase fuel consumption and emissions and can damage catalytic converters—costing from a few hundred to several thousand dollars to repair. EVAP leaks may be minor but cause failed emissions tests and reduced resale value if ignored. Misfires, if left untreated, lead to engine damage and costly repairs; addressing them early avoids expensive rebuilds. At Larry H. Miller Dodge RAM FIAT Tucson, our diagnostics identify codes precisely, and we explain costs and consequences so you can make informed choices. Our certified technicians use OEM tools to confirm whether a code indicates a sensor swap, a wiring issue, or a deeper mechanical fault. Choosing the dealership often delivers lower total cost of ownership compared with repeated fixes at independent shops because we fix the root cause once. For prompt attention and clear pricing, schedule service and check our service specials.
