2013 Ford Explorer Check Engine Light

It means the powertrain control module stored an OBD-II fault code for an emissions, engine, or transmission-related issue.

This light is your 2013 Ford Explorer’s way of flagging a system that needs attention—anything from a loose gas cap to a sensor, misfire, or catalytic converter concern. In Lakewood, our Ford scan tools read the code, view freeze-frame data, and guide pinpoint tests so we fix the cause, not just the symptom.

• OBD-II code identifies the affected system
• Could be minor (EVAP/gas cap) or serious (misfire)
• Schedule service to confirm the root cause

A steady light means drive cautiously to service; a flashing light signals a severe misfire—stop driving to prevent catalytic converter damage.

If the light is steady, limit trips and monitor for rough running or poor performance, then book diagnostics in Lakewood soon. If it flashes, continuing to drive can overheat and ruin the converter, leading to expensive repairs. Our team at Larry H. Miller Ford Lakewood can assess the risk and advise next steps.

• Flashing = misfire severe enough to damage the converter
• Steady = non-urgent fault, but don’t delay diagnosis
• Use our schedule service tool for quick booking

Common causes include O2 sensor faults, EVAP leaks (loose gas cap), MAF issues, catalytic converter efficiency faults, and cylinder misfires.

Your Explorer’s PCM tracks emissions and drivability; when readings are out of range, it stores a code. Colorado’s temperature swings can aggravate EVAP leaks, while altitude affects air/fuel calculations, making MAF and O2 data critical. We verify the exact failure with Ford diagnostic software and isolation tests.

• Altitude and temperature shifts can trigger EVAP and air/fuel codes
• Ignoring misfires can damage the converter
• Check our service specials before you book

A flashing light indicates an active severe misfire that can overheat and melt the catalytic converter.

If you see the lamp flashing, reduce power, safely pull over, and arrange diagnostics. Fuel, ignition, or compression faults can trigger this condition. Our Lakewood team can scan the PCM, examine misfire counters and freeze-frame data, and isolate the failed component to protect the exhaust system.

• Severe misfire risks costly converter damage
• Pinpoint tests confirm coil, plug, injector, or mechanical causes
• Use our schedule service link for priority booking

Parts stores read generic codes; dealer diagnostics use Ford factory scan tools and pinpoint tests to identify the exact cause.

A single code can have multiple root causes. Our technicians access manufacturer data, live PIDs, mode 6, and service messages that generic readers can’t see. You’ll get verified testing and a written estimate before any repair, reducing parts-swapping and return visits.

• Ford scan access to proprietary data and software updates
• Isolation testing confirms the failed part or system
• Written estimate provided before repairs proceed

No—resetting clears codes and readiness monitors; vehicles often fail emissions until monitors complete and the fault is fixed.

After a reset, your Explorer must run specific drive cycles so the monitors set to “ready.” If the underlying issue remains, the light will return and testing will fail. We can diagnose the cause, verify readiness, and help you prepare for inspection in the Denver metro.

• Readiness monitors must be complete to pass
• Active faults will trigger the lamp again
• Book a pre-test check via schedule service

Serving Lakewood, Denver, Littleton, Golden, Arvada, Aurora, and Westminster, our diagnostic process for your 2013 Ford Explorer combines Ford factory scan capability with methodical testing. Generic OBD-II readers only report a code; we analyze freeze-frame data, run bidirectional controls, and perform pinpoint checks to confirm the root cause. Colorado’s climate can surface cold-start faults in winter and EVAP leaks during temperature swings, so we review data across conditions and verify repairs with a road test. Find us at 11595 West 6th Avenue, Lakewood, CO 80215 for a clear plan and next steps. Have questions or ready to proceed? Please schedule service or view our service specials before you book.

We start with a full-system OBD-II scan and capture freeze-frame data to see when the fault occurred on your 2013 Ford Explorer. Next, we verify the symptom, check live data streams, and run isolation tests (vacuum/EVAP leak checks, ignition and injector assessments, and sensor circuit tests) to identify the failed component or system. You’ll receive a written estimate before any repair so you can approve the work with confidence. After repairs, monitors are confirmed ready and the vehicle is road-tested to validate the fix. To get started, choose a time via our schedule service tool or check current service specials.

Typical 2013 Ford Explorer codes include EVAP system leaks (often small leaks from hoses or a loose cap), O2 sensor and catalyst efficiency faults (affecting emissions and fuel economy), MAF correlation errors (impacting air/fuel calculations), and misfire codes (cylinder- or random-misfire). Ignoring misfires can overheat and damage the catalytic converter, turning a minor ignition repair into a costly exhaust replacement. Small EVAP leaks may start as an intermittently stored code but can escalate and cause failed inspections if left unresolved. Bring your 2013 Ford Explorer to Larry H. Miller Ford Lakewood in Lakewood for an accurate diagnosis — schedule service.
