Question

the __________ reading shows the difference between outside atmospheric pressure and the amount of vacuum (manifold pressure) in the engine. select one: a. scan tool b. pressure transducer c. cylinder leakage tester d. vacuum gauge

Explanation:

A vacuum gauge is specifically designed to measure the difference between outside atmospheric pressure and the vacuum (manifold pressure) in an engine. A scan tool is used for diagnosing vehicle systems by reading and clearing diagnostic trouble codes. A pressure transducer is a device that converts pressure into an analog electrical signal. A cylinder leakage tester is used to test for cylinder leakage.

Answer:

d. Vacuum gauge
