C: INSPECTION

1. PURGE CONTROL SOLENOID VALVE

1) Check that the purge control solenoid valve has

no deformation, cracks or other damages.

2) Measure the resistance between the purge con-

trol solenoid valve terminals.

3) Check that air does not come out from (B) when

air is blown into (A).

• Purge control solenoid valve 1

• Purge control solenoid valve 2

4) Connect the battery positive terminal to the ter-

minal No. 1 and the battery negative terminal to the

terminal No. 2. Check that air is discharged from

(B), when supplying air to (A).
