Toyota RAV4>> The control system and decrease in toxicity of the fulfilled gases>> Sensors and valves of system of injection of fuel (EFI)>> Replacement of the valve of a control system of the frequency of rotation of idling (IAC)
Frequency of rotation of idling is established at the plant and does not demand adjustment in use of the car. However when replacing throttle knot if the screw of adjustment of frequency of rotation of idling rotated, it is necessary to carry out an inspection and adjustment of frequency of rotation of idling at service station.
The IAC valve operates amount of the air coming bypassing a butterfly valve to engine cylinders at an idling rotation frequency. The valve is run by the control unit of the engine depending on engine loading (air conditioning, the steering drive with the amplifier) and the operational mode (the cold or hot engine).
You make replacement of the valve of a control system of the frequency of rotation of idling (IAC) as follows:
– remove throttle knot;
– turn out screws and remove the valve of a control system of the frequency of rotation of idling and its laying;
You make installation in the sequence, the return to removal. At installation use new laying.
