A vacuum gauge/pump is an indispensable diagnostic tool that measures the pressure (or lack thereof) within an engine's intake manifold. It helps identify a variety of engine problems, from vacuum leaks and restricted exhaust systems to incorrect engine timing and internal engine wear. This tool provides critical insights into engine health that complement OBD2 readings by offering a direct mechanical assessment.
