Moreover, a completely dead sensor may prevent the automatic transmission from properly engaging. It may also jerk when trying to give it gas. For example, sometime the vehicle may hesitate when in motion or sitting at the stop light. There are more symptoms that may display when the sensor is starting to act up. If the vehicle starts up normally, then the fault is due to a dirty mass air flow and not a failed sensor. However, before condemning a faulty sensor, use an approved air flow sensor cleaner and try spraying the filament. If the filament is dirty or contaminated then the sensor may be faulty. Take a look inside the sensor for a thin filament. Remove the sensor from the inlet tube or air filter box whichever the sensor is mounted on.

If this is the case, suspect a faulty air flow sensor. Usually, it may take a few tries to crank the engine over. However, there are a few vehicle symptoms that will tell you when it is time to replace the air flow sensor. Proper maintenance of the mass air flow and cleaning it will help prolong its life. A mass air flow typically last between 80,000 miles to 150,000 miles. It serves as a function to allow the computer to calculate the proper air and fuel mixture which should be close to 14.7 air to 1 part fuel. The function of the mass air flow sensor is to measure the amount of air entering the engine.
