Description

MAF Motorcraft Mass Air Flow Sensor 3L3A-12B579-BA for Ford Mazda F150 AFLS131 🔧 Motorcraft Mass Air Flow (MAF) Sensor (3L3A-12B579-BA) – For Ford/Lincoln/Mazda/Mercury (2003–2016) 🔧 【OE Cross-References: AFLS131 / 6L3Z-12B579-A / SU9779】Fixes Rough Idle & Check Engine Codes – 10-Minute Install (90-Day Warranty) 1. Core Features 🔹 Wide Compatibility with 2003–2016 Ford/Lincoln/Mazda/Mercury Models Engineered as a direct OEM replacement for hundreds of Ford-family vehicles, covering popular cars, trucks, SUVs, and vans. Critical for resolving performance issues caused by a faulty MAF sensor (a common failure point in aging vehicles). Key Compatible Brands & Models Brand Key Models (2003–2016) Ford F-150/F-250/F-350/F-450/F-550 Super Duty, Crown Victoria, Explorer, Mustang, Escape, Edge, Ranger, Expedition Lincoln Navigator, MKZ, MKX, MKS, Mark LT, Town Car, LS Mazda 6, CX-9, B2300/B4000, Tribute Mercury Grand Marquis, Mariner, Milan, Mountaineer, Sable Critical Compatibility Notes : For 2003–2009 Ford Explorer: Only fits models with OEM part number 3L3Z 12B579-BA (check your old sensor’s part number first). Engine-specific fit: Designed for 2.0L–6.8L gas engines and 6.0L diesel (F-Series Super Duty) – confirm your engine size matches the fitment list. 🔹 OEM-Grade Precision & Performance Built to meet or exceed original equipment standards, ensuring reliable airflow measurement (the MAF sensor’s core function): Fast response time (15ms) : Quickly adjusts to changes in throttle input, preventing hesitation or rough idle when accelerating. Tight output curve tolerance (<2%) : Delivers accurate airflow data to the engine control unit (ECU), optimizing fuel injection and ignition timing – improves fuel efficiency by 3–5% and reduces emissions. Contaminant bypass port : Built-in design filters out dust, oil, and debris from the intake air, protecting the sensor’s delicate sensing elements and extending its lifespan (up to 100,000+ miles). 6-blade terminal design : Matches OEM electrical connections, ensuring a secure, error-free link to the vehicle’s wiring harness (no "check engine" codes from poor contact). 🔹 Solves Common MAF-Related Issues A faulty MAF sensor triggers dozens of drivability problems – this replacement fixes: Rough idle (engine shakes at stops). Hesitation or lag when accelerating. Poor fuel economy (increased gas mileage). Check engine codes: P0100 (MAF Circuit Malfunction), P0101 (MAF Circuit Range/Performance), P0102 (MAF Circuit Low Input), P0103 (MAF Circuit High Input). Stalling or misfiring (especially at low speeds). 🔹 10-Minute DIY Installation No special tools or mechanical expertise needed – even beginners can replace the sensor in 3 simple steps: Disconnect the battery : Remove the negative terminal to reset the ECU and avoid electrical shorts. Remove the old sensor : Unclip the wiring harness, loosen the 2 mounting bolts (included in the sensor’s 2-hole bolt-on design), and pull out the old MAF. Install the new sensor : Slide the new MAF into the intake tube, tighten the bolts, and reconnect the wiring harness. Reattach the battery – the "check engine" light will clear within a few drive cycles (or use an OBD scanner to reset it immediately). Cost Savings : Avoid $150–$250 dealer labor fees – replace the sensor yourself for a fraction of the cost. 🔹 Durable Plastic Construction Crafted from high-temperature resistant plastic (rated to 250°F / 121°C) to withstand underhood harshness: Resists warping or cracking from engine heat. Impervious to oil and fuel vapors (common in intake systems), preventing sensor degradation. Black finish matches OEM aesthetics, blending seamlessly with the intake tube. 2.

Important Notes Compatibility Verification Check your old sensor : Match the part number on your existing MAF sensor to the "OEM/Interchange Part Numbers" list (e.g., 3L3Z-12B579-A, AFLS131). Use Amazon Confirmed Fit : For unsure fits, input your vehicle’s year, make, model, and engine size into Amazon’s "Confirmed Fit" tool to verify compatibility. Post-Installation Tips Clean the intake tube : Before installing the new MAF, wipe the inside of the intake tube with a clean, dry cloth to remove oil or debris (prevents sensor contamination). Reset the ECU : Disconnect the battery for 10 minutes after installation, or use an OBD-II scanner to clear existing codes – ensures the ECU "learns" the new sensor’s data. After-Sales Support Order Cancellations : Contact the seller ASAP if you purchase by mistake – cancel before shipping, or refuse delivery to initiate a return. Fitment/Defects : If the sensor doesn’t fit, triggers codes, or fails: Contact the seller first (before leaving feedback) – all issues are resolved within 24 hours. The 90-day warranty covers free replacements or full refunds for defective parts. Restore your vehicle’s performance and fuel efficiency with this OEM-quality MAF sensor – a quick, affordable fix for common drivability problems! 🚗
