Importance of an Electric Vacuum Pump in Power Stroke Engines

Many types of Ford diesel trucks come equipped with a powerstroke engine. These engines were first introduced in 1994 as the engine could boost horsepower while reducing exhaust gas temperatures due to its unique fuel injection and high pressure oil pump systems. Also included in such a diesel engine is an electric vacuum pump that helps operate the braking system.

What is an Electric Vacuum Pump?

An electric vacuum pump allows for the brake booster to function properly. The brake booster uses the vacuum that the internal injection engine generates from the manifold to create braking power. Unfortunately certain environmental conditions such as high altitude, or certain operations such as using the air conditioning or warming up the engine, can lessen the amount of a vacuum that the manifold creates.

When this problem occurs, you may have problems with the brakes going out. The electric vacuum pump helps to eliminate this issue by creating additional vacuum pressure going to the brake booster. Many of the newer hybrid and electric vehicles hitting the market are using electric vacuum pumps.

Problems You May Experience With a Malfunctioning Electric Vacuum Pump

If you see the brake light come on but won’t go off, you may think that something is wrong with the brake light switch. Yet if also you have problems stopping or you can’t press down brake pedal, the issue could be a malfunctioning electric vacuum pump.

You can perform the replacement of the vacuum pump yourself if you have the mechanical skills and understanding of the engine compartment. There are several manufacturers that offer replacement electric vacuum pumps. Before replacing the pump, you should check to ensure the vacuum hose is connected to the electrical vacuum pump. You can also perform a vacuum pressure test by using a vacuum test kit.
