1.Disconnect the vacuum
hoses from the swirl control valve (SCV) solenoid.
| 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 (B) of the swirl control valve (SCV)
solenoid.
4.As described in the chart below, check
airtightness by applying a vacuum with voltage
applied directly from the battery to the swirl control valve
(SCV) solenoid, and without applying
voltage.

5.Measure the resistance
between the terminals of the swirl control valve (SCV)
solenoid.
Standard value: 29 - 35 Ω
(at 20°C)
6.Replace the solenoid if
airtightness or resistance is out of specification.
