Check Engine Light Reset — 2020 Chevrolet Colorado

Resetting the check engine light on a 2020 Chevrolet Colorado may seem straightforward, but a simple reset without addressing the underlying fault risks recurring codes and unseen damage. At Larry H. Miller Chevrolet Murray in Murray, UT, our technicians first perform a complete OBD-II scan to capture freeze-frame data and active codes. This process ensures we identify whether the issue is a transient fault, a sensor malfunction, or something that requires immediate repair. We explain findings in plain language and provide direct comparisons between DIY reset options and dealer-performed diagnostics. Choosing dealer service means access to OEM replacement parts, manufacturer software updates, and technicians certified by Chevrolet — all of which contribute to longer engine life and lower ownership costs. If a reset is appropriate after repairs, our team does it correctly and logs the service for warranty and maintenance history. For convenience, you can schedule service online; review available discounts through our service specials before you come in.

2020 Chevrolet Colorado Check Engine Light Codes

Common OBD-II codes for a 2020 Chevrolet Colorado often include P0420 (catalytic converter efficiency), P0300-series (misfires), P0171/P0174 (system too lean), and sensor-related codes such as P0130–P0167 for oxygen sensor faults. Ignoring these codes can lead to progressive engine damage, poor fuel economy, failed emissions tests, and higher repair bills — for example, a neglected catalytic converter issue can escalate into a replacement labor and parts cost far exceeding early sensor repairs. At Larry H. Miller Chevrolet Murray, we combine local knowledge of Utah emissions requirements with Chevrolet factory diagnostics so we deliver fast, accurate work that saves money over time. Our approach emphasizes repair costs versus the cost of doing nothing: early sensor or ignition repairs are typically modest, while delayed action can result in component failures that cost several times more. We offer clear estimates, OEM parts, and certified tech expertise plus service financing options to help you take action now and spread the cost.
