Warning: Before disconnecting, mark the vacuum hoses so that they can be reinstalled in their proper locations.
1. Disconnect the vacuum hose from the solenoid valve.
2. Disconnect the electrical connector from the valve.
3. Connect the vacuum pump to the pipe to which the vacuum hose with the red stripe was connected.
4. Create a vacuum and check when the voltage supplied to the solenoid valve is applied and removed.
5. Measure the resistance between the terminals of the activated carbon canister cleaning solenoid valve.
Resistance: 26 Ohm at 20°C
| Battery voltage | Normal condition |
| When voltage is applied | There is no vacuum |
| When the voltage supply is interrupted | There is a vacuum |
