Check Engine Light Flashing

The check engine light flashing in a 2020 Ford Explorer is a critical warning that should prompt immediate attention.

We combine OEM diagnostic tools with manufacturer-level experience to identify root causes quickly—reducing the time your vehicle spends in the shop and lowering your overall repair costs. While independent shops may offer quick fixes, our dealership ensures transparent recommendations, factory parts, and warranty protection, which often yields greater immediate and long-term savings. We also provide service financing so you can address urgent repairs now and manage payments over time. Check our current service specials for discounts on diagnostics and repair work.

2020 Ford Explorer Check Engine Light Codes

Common check engine light codes for the 2020 Ford Explorer include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/lean conditions), P0300-P0306 (misfires), and various oxygen sensor or EVAP codes. Left unaddressed, these codes can translate to decreased fuel economy, failed emissions tests, rough idling, or damage to major components such as the catalytic converter. At Larry H. Miller Ford Lincoln Draper, our team in Draper, UT, explains the cost implications of each code and prioritizes repairs that safeguard your vehicle’s longevity and resale value. For example, replacing a faulty O2 sensor is typically far less expensive than replacing a damaged catalytic converter down the road.
