Disconnect the wire from the "negative" terminal of the battery
Loosen the clamps and disconnect hoses 1 and 2 from the regulator 5.
Disconnect the connector with wires from connector 4 of the regulator.
Unscrew the two bolts 3 fastening and remove the regulator.
Remove regulator 5 from clamp 6.
Install the new idle control in reverse order.
Checking the secondary air regulator
Turn off the ignition and remove the negative terminal from the battery.
With an awl or a thin screwdriver, we snap off the block clamp and disconnect the regulator connector.
We measure the resistance of the two windings of the regulator with an ohmmeter, for which we connect one probe of the device to the central terminal, and the other to the extreme ones in turn.
For a working regulator, the resistance of each winding should be in the range of 10-14 ohms.
Having removed the regulator from the engine, we put a piece of PVC tube on the central output and insert the end of the bare wire into it.
We connect the central terminal with the plus of the battery, the minus - alternately with the extreme ones.
In one case, the damper should open completely, in the other it should close
If it doesn't, shake the control lightly to make sure the damper is not sticking.
We replace the defective regulator.
Removing the secondary air regulator
Loosen the clamp with a screwdriver
Remove the air supply hose.
Loosen the lower hose clamp with a screwdriver.
Using a 10 key, we unscrew the two bolts securing the regulator to the intake system receiver.
Remove the regulator assembly with the bracket by removing the lower branch pipe of the regulator from the hose.
Remove the steel clamp and rubber tube from the regulator.
Install the regulator in reverse order
During installation, we are guided by the diameter of the regulator nozzles - the inlet is larger and should be located on top
