Vacuum Pressure Sensor to monitor vacuum pump & the brake booster
Hi Gang,
I am happy with the result.
It started here : https://mbworld.org/forums/e-class-w...ta-junkie.html
The result is the video below :
Because I am using absolute pressure sensor psiA and not a vacuum sensor, the closer the reading to ZERO psi, that means the closer it is to maximum vacuum of 29.92" Hg.
The closer the value is to 14.7 psi ( if at sea level ), that means I don't have vacuum reserve anymore.
If any leaks in the system occurs, be it at the vacuum pump itself, all vacuum hoses and the brake booster and if for M276 3.0 Turbo, the vacuum actuators for pulling the wastegates ( 2 units ), all can be detected
by this gauge/sensor.
