So, an adsorber of the fuel vapor recovery system is installed in the engine compartment: 1 - adsorber; 2 - solenoid valve for adsorber purge; 3 - connecting hoses.
This subsystem is used in the feedback injection system. It uses the method of trapping vapors with a carbon adsorber. It is installed in the engine compartment and is connected by pipelines to the fuel tank and throttle assembly. A solenoid valve is located on the adsorber cover, which, according to the signals from the control unit, switches the operating modes of the system.
Components of the vapor recovery system (canister, canister purge valve) removed for inspection or replacement when a persistent smell of gasoline appears, caused by leakage of components and pipelines, as well as failure of the adsorber purge valve. In addition, a violation of the canister tightness and failure of the purge valve can cause the engine to idle erratically up to a stop.
1. To replace the canister purge valve, disconnect the wiring harness connector from the valve..
2.... loosen the clamps of the vacuum and purge hoses and disconnect them, having previously marked them, in order to install them in their original places.
3. Squeeze out the plastic holder with a screwdriver..
4.... and remove the purge valve.
5. To remove the adsorber, follow steps. 1 and 2, unscrew the coupling bolt of the canister fastening clamp and remove the canister.
6. Establish knots of system of catching of vapors of fuel in sequence, return to removal.
