Fast Idle Air Valve: Notes
2001 Suzuki Grand Vitara JLS, StandardSECTION Notes
NOTE:
A Thermo wax device which is incorporated as part of throttle body, may control a plunger or air bypass valve. When coolant temperatures are low 75-78 °F (23-26°C) conditions for a higher than normal idle speed exist. As coolant temperatures raise, fast idle speed falls to a specified rpm, idle speed is then controlled by ECM/PCM and Idle Air Control (IAC) valve.
