Do I need to replace MAF sensor?
The life of your MAF sensor can be extended with regular maintenance and air filter replacement. A good rule of thumb is to drive every 10,000 to 12,000 miles. Mass airflow sensors (MAF) have no expiration date.
What causes a MAF 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.
Is it necessary to replace the MAF sensor?
MAF sensors can become damaged, but more often they just get too dirty to do their job well. In this case, they can be cleaned but if it is a mechanical or electrical failure, they must be replaced. Luckily, it’s a pretty straightforward job.
How can you tell when a MAF sensor is bad?
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. These issues can create dangerous situations causing accidents and injury.
How can I check if MAF sensor is working properly?
There’s actually 2 ways to check a MAF sensor, firstly by using diagnostics equipment (Nanocom, Hawkeye, Rovacom, etc.) to check live readings which should be 55-60 kg/hr at idle & 550-640 kg/hr at full boost. Secondly by measuring resistivity values with a multimeter (call it ‘the field method’).
What are the symptoms of a MAF sensor going bad?
These are the symptoms of a bad MAF sensor: Engine stalling, almost immediately after starting the car. Lack of power and poor acceleration. Unstable idling, especially when the A/C is on. Engine hiccup. Unable to start the car, even after turning the engine for a couple of times.
