Provides absorption of gasoline vapors in a special tank with an absorber and prevents them from entering the atmosphere. The vehicles in question are equipped with an electromagnetic purge valve for ventilation of the fuel tank, controlled by the engine processor unit. The valve is activated when the engine temperature reaches a certain level.
Gasoline vapor recovery system (CR-V 1998-99): 1. Three-way valve; 2. Ventilation valve; 3. From fuse N15 of the generator speed sensor (in the block under the dashboard); 4. Sensors; 5. Collector; 6. Purge solenoid valve; 7. Tank; 8. Tank filler cap; 9. Tank; 10. Ventilation valve; 11. Bypass solenoid valve; 12. Two-way valve; 13. Tank vapor pressure sensor
Examination
Tank
The condition of the tank is checked by external inspection.
Purge solenoid valve
A malfunction of this valve causes the diagnostic system indicator lamp on the instrument panel to light up. Remove the valve, create a vacuum in it and turn on the ignition. When the ignition is on, air leakage through the valve is not allowed. Otherwise, turn off the ignition, disconnect the connector and check the circuit between the yellow/red wire and ground. If there is a chain, then replace the valve. Otherwise, you should check the wire to the processor unit.
Removal and installation
Tank
1. Raise the vehicle.
2. Loosen the bolts, mark and disconnect the hoses and remove the tank together with the bracket.
3. Installation is carried out in reverse order.
Tank solenoid valve
1. Disconnect from the valve (mounted on the tank) vacuum hose.
2. Loosen the screws (bolts) and remove the valve from the tank.
3. Installation is carried out in reverse order.
