1. With ignition switch OFF, disconnect coupler from valve.
2. Check resistance between two terminals of tank pressure control solenoid valve.
Resistance of tank pressure
control solenoid valve: 28 - 36 Ohm at 20 °C (68 °F)
If resistance is as specified, proceed to next step. If not, replace.
3. With coupler disconnected, blow into nozzle "A". Air should come out of filter and not out of nozzle "B".
If not, replace tank pressure control solenoid valve.
4. Connect 12 V-battery to tank pressure control solenoid valve terminals.
