Description

YATO YT-0674

A vacuum pump is a multifunctional device used to diagnose systems in cars and technology whose operation is based on pressure or vacuum. It is equipped with accessories that allow use in almost any engine or system.

The YT-0674 pump is equipped with a switch, which, depending on the position, allows you to create a vacuum or pressure.

Moving the switch towards the pump outlet will cause a vacuum to be generated during pumping. The switch shifted towards the handle will cause pressure to be generated during pumping.

Measurement range: from -1 to 3 bar.

Purpose / Application

With the help of a pump, m.in diagnostics can be carried out. the following systems and arrangements:

Computerized engine control equipment:

• barometric pressure sensor (BARO)
• PVC system
• Exhaust gas recirculation system (EGR)
• thick-layer pressure sensors (MAP)

Ignition control devices:

• vacuum ignition advance
• Delay valve: SDV, RCV

Brake system:

• Classic brakes
• ABS brakes
• pneumatic brakes
• brake lines
• Brake servo

Other systems:

• air conditioning
• cruise control
• fuel tank and fuel system
• vacuum door closing system

Method of use

Diagnostics of exhaust gas recirculation system (EGR)

The EGR system valve is an example of a vacuum actuated valve. In the absence of vacuum, the valve is closed and exhaust gases do not escape from the valve. If a vacuum is brought to the valve, it is opened, allowing exhaust gases to recirculate.

Diagnostics of thick-layer pressure sensors (MAP)

• Assemble the pump and tank system as in the case of venting brake calipers, and then connect to the vacuum connection of the sensor.
• Press the pump lever until the hand shows -0,5 bar. Finish pumping and observe the hand, it should be stationary. If the hand moves, it means damage to the MAP sensor.
• During operation, the MAP sensor sends feedback signals to the control computer. The signal has a frequency between 85 Hz and 160 Hz depending on the vacuum level. A frequency meter is necessary to measure the frequency, it must be connected according to the instructions of the sensor and meter.

Brake caliper venting.

• Ensure that the brake system expansion tank is filled with fluid to the nominal volume.
• Venting should be carried out in the following order:

- brake pump, if equipped with a vent valve

- Brake calipers in order from the nearest brake pump to the furthest

• Connect the short flexible hose to the connection located on the bottom of the pump tank cover.
• Close the pump tank with the lid.
• Connect long flexible wires to the cover connections. The end of one of the long hoses connects to the pump and the other to the vent valve (calamite) of the brake caliper. Use an adapter if necessary.
• Press the pump lever 10 - 15 times to create a vacuum in the pump tank.
• Unscrew the vent valve by 1/4 - 1/2 turn, so that the pump tank fills with liquid to a height of about 5 cm. Tighten the vent valve.
• Disconnect the pump hose from the vent valve, the clamp venting procedure is completed.
• Before repeating the venting procedure in the next caliper, empty the pump tank from the brake fluid and replenish the brake fluid level in the brake system to the nominal level.
