Section 6 Carbon Canister Replacement
1. Check and replace carbon canister
(a) Eye-inspect the carbon canister for crack or damage. See (Figure 109).
(b) Check the carbon canister's operation.
1. Plug the exhaust hole. See (Figure 110).
2. Blow air in through (4.71kpa, 48kgf/cm
2
) fuel tank hole when the exhaust
hole is closed. Check and ensure air is blew out from the blow purge hole.
Replace the carbon carnister if the operation is not as specified.
3. Blow air in through the fuel tank hole. Check and ensure air flows out from
the other hole without resistance.
Replace the carbon carnister if the operation is not as specified.
(c) Clean the carbon carnister: Plug the blowing tube, bleed air in through (4.71kpa,) fuel tank hole and goes
out from the exhaust port. See (Figure 111).

2. Vacuum Solenoid Valve (VSV)
(a) Using ohmmeter, check VSV open circuit. The resistance is 27-33 ¸ when the temperature is 20°. See
(Figure 112).
(b) Using ohmmeter, check VSV grounding. Replace VSV if it is continuity. See (Figure 113).
