<Checking the relief valve>
1. Disconnect the hoses from the fuel tank solenoid valve.
2. Connect a hand vacuum pump (pressure-application type) to nipple (A) of the fuel tank solenoid valve (refer to the illustration).
3. Apply pressure to nipple A of the fuel tank solenoid valve, and check that air leaks from nipple B when it is at approximately 33 kPa {4.8 psi} or more.
4. When air does not leak at approximately 33 kPa {4.8 psi} or more, it is considered that the relief valve attached to the fuel tank solenoid valve is abnormal, so replace the evaporative emission canister.
