2023 Chevrolet Silverado 2500HD Check Engine Light Reset

Resetting a check engine light on a 2023 Chevrolet Silverado 2500HD may seem simple, but a cleared code doesn’t fix the underlying issue. Technicians at Larry H. Miller Chevrolet Murray in Murray, UT recommend a professional diagnosis before any reset because codes record conditions that can point to intermittent faults, emissions problems, or failing components. Our certified technicians use OEM-level scan tools to capture freeze-frame data, verify repair effectiveness, and ensure emissions compliance. Resetting without repair can mask a recurring fault, potentially causing reduced fuel economy, increased emissions, or long-term engine damage. Choosing dealership service provides transparency — we document findings, show repair options, and use GM-approved parts to protect warranties and vehicle longevity. We also offer service financing to help you address necessary work now and pay over time. For peace of mind and accurate repair records, schedule service and check current service specials to save on recommended maintenance.

2023 Chevrolet Silverado 2500HD Check Engine Light Codes

In Murray, UT, common check engine light codes for a 2023 Chevrolet Silverado 2500HD include P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfire), P0171 (system too lean), and P0455 (large EVAP leak). Left unaddressed, these codes escalate costs and risk: a P0420 left to progress can lead to catalytic converter failure costing $1,200–$2,500 to replace; repeated misfires (P0300) can damage pistons or the catalytic system with repair costs from a few hundred dollars to over $1,000 depending on root cause; lean conditions (P0171) reduce performance and fuel economy and often stem from intake leaks or sensor faults; EVAP leaks (P0455) can fail emissions inspections and lead to drivability issues. At Larry H. Miller Chevrolet Murray, our certified technicians prioritize fixes, explain cost-effective options, and use OEM parts to preserve long-term value. We often provide better immediate and long-term savings than independent shops, and our service plans and service specials help keep ownership costs down.
