Two technicians are discussing MAP sensors. Technician A says that the MAP sensor should be replaced if anything comes out of the sensor when the vacuum hose is removed from the sensor. Technician B says that the injector pulse width should increase when vacuum to the MAP sensor is increased. Which technician is correct?
A) Technician A only B) Technician B only C) Both technicians D) Neither technician
Question 2
