1.Disconnect the vacuum hoses from the variable geometry (VG) solenoid valve.
| note |
When disconnecting the vacuum hose, always make sure that it can be reconnected at its
original position.
|
2.Disconnect the harness connector.
|
|
3.Connect a hand vacuum pump to nipple (A) of the VG solenoid valve.
4.As described in the chart below, check airtightness by applying a vacuum with voltage
applied directly from the battery to the VG solenoid valve, and without applying voltage.

5.Measure the resistance between the terminals of the VG solenoid valve.
Standard value: 10 -
14 Ω
(at 20°C)
6.Replace the solenoid if airtightness or resistance is out of specification.
