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 measures the difference between outside atmospheric pressure and the vacuum (manifold pressure) in the engine. A scan tool is for reading diagnostic trouble codes and vehicle data. A pressure transducer converts pressure into an electrical signal. A cylinder leakage tester checks for leakage in the cylinder.

Answer:

d. Vacuum gauge
