Solenoid: Testing and Inspection
SOLENOID VALVE OPERATION CHECK
1. Remove the vacuum hoses (blue stripe, yellow stripe) from the solenoid valves.
2. Disconnect the harness connectors.
3. Connect a hand vacuum pump to solenoid valve A. Apply negative pressure and carry out the following inspections.
1. Even if the hand pump is operated with no other operation, no negative pressure develops.
2. Even when battery positive voltage is applied to solenoid A, the condition is the same as in (1). But when the vacuum hose of solenoid B is
blocked by bending at the mark, negative pressure is maintained.
3. When battery voltage is applied to solenoids A and B, negative pressure is maintained.
4. Connect the hand vacuum pump to solenoid valve B. Apply negative pressure and carry out the following inspections.
1. With no change, negative pressure is maintained.
2. When battery voltage is applied to solenoid valve B, the vacuum shuts off.
3. When battery voltage is applied to solenoid valve A, the vacuum shuts off.
5. Measure the resistance of the solenoid valves.
Standard value: 36 - 46 ohms [at 20° C(68° F)]
6. Replace the solenoid valve if not within the standard value.
