Question

Technician A states that a speed density system means that the PCM uses MAP, TP, and engine crankshaft speed to calculate the amount of air flowing into the engine. Technician B states that the amount of air flowing into the engine can be a direct reading from the MAF. Who is correct

Answer 1

Answer:

Both of them are correct

Explanation:

PCM uses MAP, TP, and engine crankshaft speed to calculate the amount of air flowing into the engine, while  the amount of air flowing into the engine can be a direct reading from the MAF
