What are the symptoms of a faulty MAF sensor?
Symptoms of a faulty mass air flow (MAF) sensor may include: The MAF sensor measures the volume and density of the air entering the engine. Some also measure the temperature of the air entering the engine.
Is the Ford mass air flow ( MAF ) sensor inside?
Ford has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.
Can a MAF sensor help with shift timing?
On a car with an automatic transmission, the MAF sensor may help with shift timing as well. Although there are two common types of MAF sensors, hot-wire and hot-film, hot-wire types are the most common. Troubleshooting test procedures for hot-wire sensors may vary from one vehicle make to the next.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.

What kind of air flow sensor do I need for my MAF?
Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.
What happens if the mass air flow sensor is not working?
The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter, so that the ECU can adjust the amount of fuel getting into the engine. If the mass air flow sensor isn’t working properly then you will be faced with one or more symptoms such as lack of power and bad fuel economy.
Where is the MAF sensor on my car?
You may also notice you’re filling up at the gas station more than usual. MAF sensors are located between the air filter and the throttle body and are responsible for measuring the amount of air entering the engine. Most vehicles have a hot wire MAF sensor. It has one heated wire and one ambient temperature wire.
What happens when a mass air flow sensor goes bad?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.
Can a bad MAF sensor cause poor drivability?
A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street.
Do you have to reprogram the MAF sesnor?
No, you should not have to reprogram the computer. Is there any cracks or air leaks between the MAF sesnor and throttle body? You might have a bad new mass air flow sensor. Experience: ASE certified tech ADVANCED LEVEL PERFORMANCE. Wisconsin certified emissions state inspector
