Check Engine Light Flashing

The check engine light flashing in a 2016 Ford F-150 signals an active misfire or an issue severe enough to risk catalytic converter damage and poor drivability.

Miller Ford Mesa in Mesa, AZ, our Ford-certified technicians prioritize rapid diagnosis using OEM scan tools to identify misfires, ignition faults, or fuel delivery problems. We balance speed with accuracy — providing a transparent estimate and explaining short- and long-term savings.

2016 Ford F-150 Check Engine Light Reset

Resetting the check engine light on a 2016 Ford F-150 may remove the warning temporarily, but it does not fix the underlying condition. Our technicians at Larry H. Miller Ford Mesa explain why a simple reset isn’t a solution: stored codes and pending readiness monitors are essential for accurate diagnostics, emissions compliance, and preserving warranty coverage. Using OEM diagnostic tools, we identify and repair the root cause — from sensors to emission controls — then perform a controlled reset and road test to confirm the issue is resolved. Choosing dealership service ensures OEM parts, documented procedures, and warranty protection, which independent shops may not provide. We also emphasize transparent pricing and immediate plus long-term savings: proper repairs now avoid repeated visits, improve fuel economy, and prevent costly cascade failures. If timing is a concern, our team offers service financing and convenient online booking — schedule appointment today — and check current service specials to reduce costs while receiving expert Ford care.

2016 Ford F-150 Check Engine Light Codes

Common check engine light codes for the 2016 Ford F-150 include P0420 (catalyst efficiency), P0300 (random/multiple misfire), P0171/P0174 (lean condition), and P0135 (O2 sensor heater circuit). Left unchecked, each can lead to escalating costs: a misfire can damage the catalytic converter, turning a modest ignition repair into a multi-thousand dollar replacement; a P0420 may signal catalytic deterioration that affects emissions testing and resale value; O2 sensor faults and lean conditions reduce fuel economy and accelerate engine wear. At Larry H. Miller Ford Mesa in Mesa, AZ, we diagnose codes precisely, explain repair implications, and provide estimates that show immediate and lifetime savings from timely, OEM-quality repairs. Our service center leverages factory diagnostics, genuine Ford parts, and certified technicians to restore performance and preserve factory warranties.
