Yes. The 2016 Ford Explorer uses a mass air flow (MAF) sensor to measure the amount of air entering the engine, allowing the vehicle’s computer to regulate fuel delivery accurately.
In the 2016 Explorer, the MAF sensor is a standard part of the engine-management system across the lineup. It is typically located in the intake duct between the air filter box and the throttle body. The sensor is usually of the hot-wire or hot-film type and plays a central role in maintaining the correct air-fuel ratio for efficient combustion.
What a mass air flow sensor does
The MAF sensor gauges the mass of air entering the engine and sends a signal to the engine control unit (ECU) so it can adjust fuel injectors to match the incoming air. On a 2016 Explorer, you’ll generally find it in the intake duct between the air filter housing and the throttle body; it’s designed to respond to airflow with a changing electrical resistance.
Key facts about the MAF sensor’s role and placement:
- Purpose: measures air mass to help the ECU calculate the correct fuel delivery (grams per second).
- Location: typically in the intake duct between the air filter box and the throttle body.
- Design: usually a hot-wire or hot-film sensor that changes resistance with airflow.
- Impact: faulty readings can disrupt the air-fuel mixture, affecting idle, power, and fuel economy.
In short, the MAF sensor is a standard component across the Explorer’s engines and is generally accessible for inspection or replacement in the air intake path.
Common symptoms of a failing MAF sensor
If the MAF sensor begins to fail, several telltale signs may appear. These symptoms can also be caused by other issues, so a proper diagnostic check is recommended.
- Check Engine light with codes such as P0100–P0104.
- Rough idle or engine stalling.
- Hesitation or reduced power during acceleration.
- Decreased fuel economy and irregular engine performance.
- Possible lean or rich-running conditions, which may manifest as rough running or misfires.
If you notice these symptoms, have the vehicle scanned to confirm whether the MAF sensor is at fault or if another issue is involved.
Maintenance and replacement tips
Maintenance and replacement of the MAF sensor should be done carefully to avoid damaging the sensor or air intake system.
- Turn off the ignition and disconnect the negative battery lead to prevent shorts.
- Locate the MAF sensor in the intake duct between the air filter box and the throttle body.
- Disconnect the electrical connector and carefully remove the sensor from its housing.
- Clean the sensor with a dedicated MAF sensor cleaner. Do not use carburetor or solvent cleaners that can leave residues or damage the sensor.
- Reinstall the sensor, reconnect the electrical connector, and restore power by reconnecting the battery.
- If cleaning doesn’t resolve symptoms, consider replacing the sensor with an OEM or reputable aftermarket unit.
Note: Replacement costs can vary based on engine type and supplier. Labor and parts for a new MAF sensor typically range from modest to substantial, so obtain a concrete estimate before service.
Summary
Yes—the 2016 Ford Explorer does have a mass air flow sensor. It sits in the intake tract and helps the ECU regulate fuel delivery for optimal performance and efficiency. Common symptoms of a faulty MAF include rough idle, poor acceleration, and a check engine light, and cleaning or replacing the sensor is a straightforward maintenance task when performed carefully.
