The idle air control valve (IAC) is a component in the engine's air intake system that regulates idle speed. It controls the amount of air bypassing the throttle plate to maintain a stable and consistent idle, especially when the throttle is closed.

The IAC valve receives signals from the engine control unit (ECU) and adjusts the airflow accordingly. If the IAC valve malfunctions or gets dirty, it can cause problems such as erratic idle speed, stalling, or rough idling. Regular maintenance and cleaning of the IAC valve can help ensure proper engine performance.

COMMON QUESTIONS

Is this a 4-pin or 2-pin connector?
This unit is the 4-pin square connector version. It is a direct replacement for the stepper motor found on the plenum chamber of Land Rover V8 and Jaguar AJ6 engines.

Why is my engine stalling when I turn the AC on?
A faulty IAC valve cannot adjust the air bypass quickly enough to compensate for the extra engine load from the air conditioning compressor. Replacing the valve usually resolves this issue.

Is this suitable for my Holden Camira?
Yes it fits the JD and JB Camira 1.8L models with Multi-Point or Single-Point Fuel Injection.
