Engine Mount Control Actuator: Testing and Inspection

2GR-FE ENGINE CONTROL: VACUUM SWITCHING VALVE (for Engine Mounting): INSPECTION

1. INSPECT DUTY VACUUM SWITCHING VALVE (OPERATION)

(a) Check the operation of the duty vacuum switching valve when positive battery voltage is applied to its terminals.





Positive battery voltage is not applied:

The air from pipe G flows out through pipes E and H.

Positive battery voltage is applied:

The air from pipe F flows out through pipes E and H.

2. INSPECT DUTY VACUUM SWITCHING VALVE (RESISTANCE)

(a) Measure the resistance according to the value(s) in the table below.





Standard resistance:





(b) If the resistance is not as specified, replace the duty vacuum switching valve.
