Can I run my car without a MAF sensor?
While the vehicle may run with a dirty or broken MAF, it will not be efficient and may cause mechanical damage to the engine due to running in a lean condition. A failed MAF sensor may not send any airflow information to the PCM. By disconnecting the sensor the ECU switches to limp mode and the car may idle better .

How does the mass airflow sensor work on a new car?
The stock mass airflow sensor is designed for stock tuning (air and fuel flow) and will not automatically re-calibrate for additional air flow. Upgraded intakes can lose power with newer cars because most use MAF-based fueling. With a change of pipe size, the fueling is affected, and the factory ECU is calibrated to the stock size.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.

What should I do if I Change my MAF sensor?
1. Remove the air filter element. Then, vacuum out all dust/dirt/debris found inside both halves of the air filter housing. CAUTION: Make sure all dust/dirt/debris is removed from the air filter housing in order to prevent a repeat incident.
