2016 Ram 2500 Check Engine Light Reset

Resetting the check engine light on a 2016 Ram 2500 may seem straightforward — a code-clearing tool will turn the lamp off — but a reset without proper diagnosis risks masking persistent faults and can lead to more expensive repairs later. At Larry H. Miller Chrysler Jeep Dodge Ram Boise in Boise, ID, we explain the difference between a temporary reset and a complete repair. Our technicians use OEM-level diagnostics to read pending and stored codes, verify repairs with live data, and clear codes only after confirming the underlying cause is corrected. For example, a battery-related voltage fluctuation can intermittently trigger engine management errors; replacing or load-testing the battery and charging system prevents repeated codes. Choosing dealership service delivers added benefits: warranty protection, OEM parts, and technician certification that help preserve your truck's performance and resale value. We also offer service financing and seasonal service specials to reduce out-of-pocket cost. Ready for a reliable fix?

2016 Ram 2500 Check Engine Light Codes

Common engine codes on a 2016 Ram 2500 include oxygen sensor (P0130–P0167), misfire codes (P0300–P0312), catalytic converter efficiency (P0420), and fuel system or sensor faults. Left unaddressed, each carries escalating costs: oxygen sensor failure reduces fuel efficiency and can damage catalytic converters; misfires can harm pistons and lead to expensive repairs; and unresolved fuel or ignition issues shorten component life and reduce towing reliability — a critical consideration for Ram 2500 owners who rely on their truck’s 15,090-lb towing capability. At Larry H. Miller Chrysler Jeep Dodge Ram Boise we provide clear cost estimates and emphasize immediate and long-term savings from proper diagnosis and OEM repairs. Our factory-trained technicians prioritize quick turnaround, genuine parts, and documentation that preserves warranty coverage. We also inspect the battery and charging system as part of diagnostics — many codes can stem from low voltage or failing battery connections. Check our current service specials and schedule appointment to get a full code scan and a warranty-supported repair plan.

Miller Chrysler Jeep Dodge Ram Boise we treat flashing codes as urgent: our technicians will prioritize diagnostics, test the battery and charging system, inspect ignition and fuel systems, and give a clear estimate of necessary repairs.
