When testing a MAP sensor that produces an analog voltage signal with 18 in. hg. applied to the sensor, the sensor signal is l.4 volts. When 13 in. hg. is supplied to the sensor, the sensor signal should be which of these voltage values?
A) 2.3
B) 2.6
C) 1.4
D) 1.6

Question

Quizplus · Accepted Answer

The MAP sensor voltage increases as the vacuum decreases. With 18 in. hg., the voltage is 1.4 volts. At 13 in. hg., the vacuum is less, so the voltage should be higher, making 2.3 volts the correct choice.
