Feedback Control Solenoid Valve








The feedback control system is designed to provide a stoichiometric air-fuel ratio, allowing the three-way catalyst's performance to give a simultaneous reduction of hydrocarbons, carbon monoxide and oxides of nitrogen. The feedback control solenoid valve is provided to stop feedback operation at low engine speed such as at engine idling.
