Two technicians are discussing testing 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 onlyb. technician b onlyc. both technicians a and bd. neither technician a nor b

The statements from both Technicians A and B are correct.

Option C

Explanation:

A typical MAP sensors comprises with a ceramic or silicon wafers, sealed with an ideal vacuum on one side and a suction manifold on the other. When the engine (motor) vacuum varies, the differential pressure across the board changes the output voltage or frequency to the MAP sensor. So, sensor vacuum to be increased if injection pulse widths increase.

Most pressure sensors operate at 5 volts from a computer and return a signal (voltage or frequency) based on the pressure applied to the sensor (vacuum). When testing the MAP sensor, make sure that the vacuum hose and hose connections are tightly connected to the engine vacuum source. According to this, concluding that the statements from both technicians are correct.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
