Where is the airflow sensor located?
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.
How do I know if my airflow sensor is bad?
Symptoms of a Faulty Mass Air Flow Sensor
- The engine is very hard to start or turn over.
- The engine stalls shortly after starting.
- The engine hesitates or drags while under load or idle.
- Hesitation and jerking during acceleration.
- The engine hiccups.
- Excessively rich or lean idling.
What does a bad mass air flow sensor look like?
Symptoms of a Faulty Mass Air Flow Sensor The engine is very hard to start or turn over. The engine stalls shortly after starting. The engine hesitates or drags while under load or idle. Hesitation and jerking during acceleration.
What happens when air flow sensor goes bad?
A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel. As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.
What causes a mass airflow sensor to go bad?
Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling, poor acceleration or even stalling.
How do you test an air flow sensor?
Connect the black lead of the multimeter to the signal ground terminal of the MAF sensor and connect the red lead to the battery positive source or the positive wire inside the MAF sensor connector. Turn the ignition of the car on. If you get 5 to 12 volts, then it is working correctly.
Does the mass airflow sensor have a fuse?
There is a fuse for the maf sensor, but it is not the same one that runs most of the other stuff on that side of the engine bay. The code you get is for a dead maf, usually when the fuse pops.
