Mass Airflow Sensor for Ford Ecosport BK BL Mustang GEN6 GT 5.0L V8 8V2112B579AA
Direct Fit Replaces 8V2112B579AA
BRAND NEW *OEM Quality* mass airflow sensor for Ford Ecosport BK BL 1.0L EcoBoost and Mustang GEN6 FM GT 5.0L V8 Coyote.
Two very different engines, one shared Ford MAF housing - a drifting sensor on either one shows up as hesitation off idle or a rich/lean fault code, not a dramatic failure. This is a direct-fit replacement, verified fitment for both platforms, dispatched from Melbourne.

ABOUT THIS SENSOR
The MAF sensor measures incoming air so the ECU can set the correct air-fuel ratio. On the Coyote V8 a weak signal commonly triggers rich/lean fault codes P0171/P0174 and a noticeable loss of power; on the Ecosport's small turbo-three it shows up as hesitation off idle.
Built to original fit, form and function for a straight swap on either vehicle.
COMMON SYMPTOMS OF FAILURE
- Hesitation or flat spot off idle (Ecosport)
- Noticeable power loss or rough running (Mustang V8)
- Engine management light with fault codes P0171/P0174
- Reduced fuel economy
- Vehicle entering reduced-power/limp mode

Can I clean my MAF sensor instead of replacing it?
Yes - if the sensor is contaminated rather than electrically failed, cleaning with a dedicated MAF sensor cleaner spray can restore correct readings. Do not use brake cleaner or generic electrical contact cleaner as these leave residue that damages the sensing wire. Allow the sensor to dry completely before reinstalling. If cleaning does not resolve the fault codes, the sensor requires replacement.
What is the difference between a MAF sensor and a MAP sensor?
A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine using a hot wire element in the intake. A MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure to calculate air density. Most modern engines use one or the other - some use both. Your vehicle service manual or OBD2 fault codes will confirm which sensor type your engine uses.
Will a faulty MAF sensor cause my vehicle to fail an emissions test?
Yes. A faulty MAF sensor causes the ECU to miscalculate fuel delivery, typically resulting in a rich running condition that increases CO and hydrocarbon emissions. Most roadworthy and emissions checks will fail a vehicle with an active MAF sensor fault code or visibly excessive exhaust smoke.
What are the symptoms of a bad MAF sensor?
Common symptoms include rough idle, hesitation or stumbling on acceleration, poor fuel economy, black smoke from the exhaust, and an illuminated Check Engine light. Your ECU may log fault codes P0100 to P0104.
Can I drive with a faulty MAF sensor?
You can drive short distances but it is not recommended. A faulty MAF sensor causes the ECU to run incorrect fuel mixtures, which can damage the catalytic converter and O2 sensors over time. Have it replaced as soon as possible.
How do I test if my MAF sensor is bad?
Use an OBD2 scanner to check for fault codes P0100-P0104. You can also use a multimeter or live data scanner to check the sensor output voltage against your vehicle's specification. A reading significantly outside spec confirms a faulty sensor.
What causes a MAF sensor to fail?
The most common causes are a dirty or contaminated sensing element (often from a missing or damaged air filter), oil contamination from an over-oiled aftermarket air filter, heat damage, or general wear over time.
Do I need to reset my ECU after replacing the MAF sensor?
It is good practice to clear any stored fault codes using an OBD2 scanner after replacement. Some vehicles will self-adapt within a short drive cycle, but clearing codes ensures the ECU recalibrates from a clean baseline.
