For accurate MAF transfer, which statement is correct?

For accurate MAF transfer, which statement is correct?

• A. Only statement A is correct
• B. Only statement B is correct
• C. Both statements are correct
• D. Neither statement is correct

Answer: (C)

Accurate MAF transfer means the mapping from the sensor signal to mass air flow must stay true across the engine’s entire operating range and adapt to changing air density from temperature and pressure. If the two statements in the question address these two essential needs—validity over the full range and proper compensation for air density—then each is true, so both are correct. Relying on only one aspect would leave the other unaccounted for, leading to errors in estimating air mass and, consequently, fueling. That’s why the right choice is that both statements are correct.
