Fast Idle Air Valve: XL-7

WARNING: This page is about a different car, the 2003 Suzuki XL-7, 2003 Suzuki Vitara, 2003 Suzuki Grand Vitara, and 2003 Suzuki Aerio. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This model uses thermo wax to control an air bypass valve inside throttle body.

Ignition off, with coolant temperature at 75-78°F (23-26°C), disconnect Idle Air Control (IAC) valve. Start engine, check that higher than normal idle speed exist. As engine coolant temperatures raise, fast idle speed should gradually reduce. If results are as specified, fast idle air valve is in good condition. If not as specified, valve could be faulty or coolant passage could be blocked.
