Question

Quizplus · Accepted Answer

Vacuum testers are indeed designed to diagnose engine problems by measuring the vacuum pressure in the intake manifold, which can help identify issues such as leaks or performance problems. They can also be used on computer-controlled vehicles, as these vehicles still rely on vacuum for various systems and the diagnostic principles remain the same.
