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

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