Technician A says that a heavy engine load results in high intake manifold vacuum and a high MAP sensor signal voltage. Technician B says that a manifold absolute pressure (MAP) sensor uses a perfect vacuum (zero absolute pressure) in the sensor to determine the pressure. Who is right?
◦ Technician A only
◦ Technician B only
◦ Both technicians A and B
◦ Neither technician A nor B
