The MAF sensor can have adjustable calibration settings.

The MAF sensor can have adjustable calibration settings.

• A. Throttle body
• B. High performance intake manifold
• C. Performance air filter
• D. MAF sensor

Answer: (D)

The main idea here is how the system translates the air entering the engine into a signal the ECU can use. The mass airflow sensor is designed to be calibrated so its output accurately reflects the actual mass of air entering the engine. This calibration helps ensure the ECU sets the correct fuel amount, even when conditions or hardware change—for example, due to air density, temperature, or modifications in the intake path. The other parts—throttle body, intake manifold, and a performance air filter—affect how much air flows but don’t provide a method to adjust the sensor’s measurement itself. Therefore, the component that can have adjustable calibration settings is the MAF sensor.
