2. Apply 12 volts DC to EVAP canister vent control va
lve. The valve will close. (Continue to apply 12 volts
until the end of test.)
3. Pressurize the EVAP line using pressure pump with 1.3 to 2.7 kPa (10 to 20 mmHg, 0.39 to 0.79 inHg),
then remove pump and EVAP service port adapter.
CAUTION:
 Never use compressed air or a high pressure pump.
 Do not exceed 4.12 kPa (0.042 kg/cm
2, 0.6 psi) of pressure in the system.
4. Using EVAP leak detector, locate the EVAP leak. For the leak
detector, refer to the instruction manual for more details. Refer
to EC-40, "
Description".

POR RECOVERY (ORVR)
System DescriptionINFOID:0000000001326504
From the beginning of refueling, the air and vapor insi de 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.
 Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
 Be sure 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-pr oof container and put lid on securely.
- Release fuel pressure from fuel line. Refer to EC-665, "
Fuel Pressure Check".
- Disconnect battery ground cable.
 Always replace O-ring when the fuel gauge retainer is removed.
 Do not kink or twist hose and tube when they are installed.
 Do not tighten hose and clamps excessively to avoid damaging hoses.
 After installation, run engine an d check for fuel leaks at connection.
 Do not attempt to top off the fuel tank afte r the fuel pump nozzle shuts off automatically.
Continued refueling may cause fu el overflow, resulting in fuel spray and possibly a fire.
