Plan for about {{service.duration_minutes}} minutes for a complete diagnostic on a 2016 Ford F-250 Super Duty.

Time varies based on the fault and whether isolation testing is required. Our Mesa technicians start with an OBD-II scan and freeze-frame review, then perform targeted tests to confirm the root cause. Book a time that works for you with our online schedule service tool.

• Initial scan and data review included
• Additional time if multiple faults are stored
• Written findings before repairs begin

It means the powertrain control module stored an OBD-II fault code, such as P0442 (EVAP leak) or P0301 (cylinder 1 misfire).

The indicator signals an emissions or engine management issue that may affect performance or fuel economy. Some causes are minor, like a loose gas cap; others, like misfires, can damage the catalytic converter if ignored. Our Mesa team reads manufacturer-specific data to pinpoint the problem.

• OBD-II codes identify the affected system
• Severity ranges from minor to urgent
• Prompt diagnosis prevents costlier repairs

The five most common causes on a 2016 Ford F-250 Super Duty are a faulty O2 sensor, EVAP leak, dirty MAF sensor, catalytic converter efficiency issue, or an engine misfire.

These issues can trigger poor fuel economy, rough running, or readiness monitor failures. Our Mesa service department isolates the root cause rather than swapping parts, helping protect your Super Duty’s emissions system. Schedule a diagnostic to confirm the fix.

• O2 sensor and MAF faults affect fuel trims
• EVAP leaks often set small/large leak codes
• Misfires can overheat/damage the catalytic converter

A steady light usually allows cautious driving to our Mesa service center, but a flashing light means a severe misfire—stop driving to prevent catalytic converter damage.

If performance feels normal and the light is steady, avoid heavy loads and schedule an appointment soon. If it’s flashing, reduce speed safely and arrange a tow. Our technicians can quickly assess your truck and advise next steps.

• Steady light: drive gently and book service
• Flashing light: tow recommended to avoid damage
• Addressing faults early lowers repair risk

Parts stores provide a free code read, while LHM Ford Mesa performs full diagnostics with Ford factory scan tools that access manufacturer-specific data.

One code can have multiple root causes; replacing parts based only on a generic code often misses the real issue. Our OEM-trained technicians review freeze-frame data, run pinpoint tests, and provide a written estimate. That process saves time and helps avoid repeat visits.

• Factory scan access to live data and proprietary tests
• Isolation testing confirms the true fault
• Clear, written findings before any repair

Your appointment starts with an initial OBD-II scan to capture active, pending, and history codes on your 2016 Ford F-250 Super Duty.

You’ll receive a written estimate before any repair so you can approve the work with confidence. We use Ford-approved equipment and genuine parts to ensure accurate results and durable fixes.

On the 2016 Ford F-250 Super Duty, common codes include P0442 (small EVAP leak), P0171/P0174 (system too lean), P0101 (MAF range/performance), P0420 (catalyst efficiency below threshold), and P0300–P0308 (random/specific cylinder misfire). Each points to a system, not a single guaranteed part failure, so confirmation testing is essential. Ignoring misfire codes can overheat and damage the catalytic converter, turning a simple ignition or fuel issue into a far more expensive repair. EVAP leaks left unresolved can prevent readiness monitors from setting and may lead to failed emissions testing. Bring your 2016 Ford F-250 Super Duty to Larry H.
