Question

mass air flow (maf) sensors are being discussed. • autozoner a says: “the maf sensor gives the computer air density, temperature and altitude data.” • autozoner b says: “the computer uses the maf sensor signal to maintain the proper air/fuel ratio.” who is correct? autozoner a autozoner b both autozoners neither autozoner

Explanation:

The Mass - Air Flow (MAF) sensor measures the mass of air entering the engine. The engine control unit (computer) uses this information to calculate and maintain the proper air - fuel ratio for efficient combustion. It does not directly give the computer air density, temperature, and altitude data. Air density, temperature, and altitude data are usually provided by other sensors like the intake air temperature sensor, barometric pressure sensor etc.

Answer:

B. AutoZoner B
