The vacuum pump pressure gauge measures pressure and vacuum in gasoline engines, helping diagnose problems such as misfiring, low compression, an incorrect air-fuel mixture, and incorrect ignition timing. It can also be used to detect leaks in injectors and fuel pumps, check valve operation, and test mechanical and electric fuel pumps, except high-pressure pumps. It can also be used to monitor TurboBoost pressure up to 0.7 bar.
