It means the OBD-II system stored a diagnostic trouble code (DTC) identifying the affected system on your 2016 Ford Explorer.

The light can indicate anything from a loose gas cap (EVAP) to a misfire, sensor fault, or catalytic converter efficiency issue. A scan reads the exact DTC, while freeze-frame data shows conditions at the moment of the fault. For Mesa drivers, our team at Larry H. Miller Ford Mesa provides code-specific testing and a clear plan to fix the root cause.

• Code read pinpoints the affected system
• Freeze-frame data speeds accurate diagnosis
• Written estimate with OEM repair guidance

The five most common causes are O2 sensor faults, EVAP leaks (often a loose gas cap), MAF sensor issues, catalytic converter efficiency codes, and ignition misfires.

On the 2016 Ford Explorer, any of these can trigger a DTC and illuminate the light. Our Mesa service department verifies the cause with factory diagnostics—sometimes a simple cap replacement fixes it; other times ignition or emissions parts require service. Prompt diagnosis helps protect components like the catalytic converter.

• Scan tool data plus smoke/voltage tests confirm faults
• Ignoring misfires can overheat and damage the catalyst
• We provide a written repair plan before work begins

A steady light means drive cautiously to service; a flashing light indicates a severe misfire—stop driving and arrange a tow.

• Flashing light = misfire risk to the catalyst
• Steady light = service soon; avoid hard acceleration
• Schedule an appointment for a proper diagnosis

Parts stores read codes; dealer technicians diagnose causes using factory scan data, guided tests, and Ford repair information.

No—clearing codes resets OBD-II readiness monitors, and most emissions programs check that monitors are set with no active faults.

• Proper repair clears the fault and allows monitors to set
• Drive cycle completion is required after repairs
• Schedule service to diagnose and verify readiness
