Note. The idle air control forms a single unit with the idle throttle position sensor and the potentiometric throttle position sensor.
Switch off the ignition.
Disconnect the 8-pin throttle position sensor connector (pic. 2-125). connect an ohmmeter to the leads «2» and «1» sensor pads and check the resistance, which should be in the range of 3-200 ohms with the throttle closed.
