Idle Air Control (IAC) Valve Replacement

2.0L Throttle Body (turbo):

IAC Valve Installation:

REMOVAL:

1. Disconnect the electrical connector from the idle control valve.
2. Remove the idle air control valve, using a 32 mm (1-1/4") wrench.

INSTALLATION:

NOTE: Before installing the new idle air control valve, measure the distance that the valve is extended. The measurement should be made from the motor housing to the end of the cone. The distance should be no greater than 28 mm (1-1/8"). If the cone is extended too far, damage may occur to the valve when installed.

Identify the replacement IAC valve as being either Type 1 (having a collar at the electric collar end) or Type II (without collar). If the measured dimension is greater than 28 mm (1-1/8"), the distance must be reduced as follows:

Type I: Exert firm pressure on the valve to retract it. (A slight side-to-side movement may be helpful).

Type II: Compress the retaining spring from the valve while turning the valve "in" with a clockwise motion. Return the spring to the original position with the straight portion of the spring end aligned with the flat surface of the valve.

1. Install the new idle air control valve to the throttle body. Use a new gasket supplied with the assembly. Tighten the valve to 18 N-m (13 lb. ft.).
2. Connect the electrical connector to the idle air control valve.
