FUEL TANK SOLENOID VALVE CHECK
 
 
<Checking the Solenoid Valve Coil Resistance>
1. Disconnect the harness connector.
2. Measure the resistance between the terminals of the fuel tank solenoid valve.
Standard value: 25 - 30 Ω [at 20°C (68°F)]
3. Replace the evaporative emission canister if resistance is out of specification.
 
 
 
<Checking the Solenoid Valve Operation>
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. As described in the chart below, check airtightness by applying a pressure of approximately 25 kPa {3.6 psi} with voltage applied directly from the battery to the fuel tank solenoid valve and without applying voltage.

4. Replace the evaporative emission canister if airtightness is out of specification.
 
 
 
<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.
