ON BOARD REFUELING VAPOR RECOVERY (ORVR)
Description
INFOID:0000000009720228
From the beginning of refueling, the air and vapor inside the fuel tank go through refueling EVAP vapor cut
valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is
released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and
refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged
during driving.
WARNING:
When conducting inspections below, be sure to observe the following:
• Put a “CAUTION: FLAMMABLE” sign in workshop.
• Never smoke while servicing fuel system. Keep open flames and sparks away from work area.
• Always to furnish the workshop with a CO
2
fire extinguisher.
CAUTION:
• Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof container and put lid on securely.
- Release fuel pressure from fuel line. Refer to
- Disconnect battery ground cable.
• Always replace O-ring when the fuel gauge retainer is removed.
• Never kink or twist hose and tube when they are installed.
• Never tighten hose and clamps excessively to avoid damaging hoses.
• After installation, run engine and check for fuel leakage at connections.
• Never attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
