Choosing Larry H. Miller Dodge RAM FIAT Tucson ensures transparency—detailed estimates, documented repairs, and warranty-backed parts and labor.

2024 Ram 3500 Check Engine Light Codes

Common check engine light codes for a 2024 Ram 3500 include sensor and turbo-related faults: codes like P0101 (MAF sensor), P0234 (turbo overboost), P0299 (turbo underboost), and various emissions-related codes. Left untreated, a faulty MAF sensor can reduce fuel economy and trigger rough running; replacing a sensor may cost a few hundred dollars but avoids wasted fuel and drivability issues. Turbo faults can escalate—what begins as a sensor or actuator repair (a few hundred dollars) can turn into turbo replacement or major engine work costing thousands if neglected. Catalytic converter or soot-related failures on a diesel can also be costly; prompt diagnostics and OEM repairs reduce the chance of expensive downstream damage. At Larry H. Miller Dodge RAM FIAT Tucson we combine local convenience in Tucson with factory-grade tools and trained technicians to diagnose codes quickly, explain cost-effective repair paths, and perform work that protects vehicle value. Our approach emphasizes transparency, immediate and long-term savings, and warranty integrity—plus service financing and ongoing service specials to make care affordable.
