Connecting The Manometer

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

Expose the canister purge (CP) valve.

Disconnect the hose (1) between the EVAP canister and the EVAP canister purge valve.

Connect manometer 9995646 to the hose (1) and the pressure regulator 9995544 to the manometer.

CAUTION:

The cock should face the pressure regulator.

Connect compressed air to the pressure regulator

Set the pressure to a maximum of 7 kPa (read off from manometer 999 5646).

Pressurize the fuel tank system by turning the cock at right angles to the hoses.

Allow pressure to build up in the tank system.

Check that the system does not leak.

Stop the pressurization by turning the cock towards the hose (1) as illustrated in A.

NOTE:

A certain amount of leakage may occur from the leak diagnostic unit. The pressure may therefore drop when the pressurization is stopped. This is normal. The leakage is caused because the pressurization is not carried out using the leak diagnostic unit.

CAUTION:

Never leave the car unattended with the tank system pressurized
