WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sienna, 2002 Toyota Sequoia, and 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Acoustic Control Induction System (ACIS) uses intake air control valve on end of air intake chamber. See Fig 1. Using 3-way connector, connect vacuum gauge in vacuum line to actuator valve. See Fig 1. Actuator valve is located at end of air intake chamber and may also be referred to as the actuator.
- Start engine. With engine idling, ensure no vacuum reading is obtained. Fully open throttle and ensure vacuum reading momentarily reads approximately 7.9 in. Hg and actuator valve rod pulls inward. If actuator valve rod does not pull inward, go to next step. If actuator valve rod pulls inward, system is operating properly.
- Disconnect vacuum hose from actuator valve. Using vacuum pump, apply 7.9 in. Hg of vacuum to actuator valve. Ensure actuator valve rod pulls inward and remains pulled inward for at least one minute. If actuator valve operates properly, reconnect vacuum hose. Check ACIS control circuit. See ACOUSTIC CONTROL INDUCTION SYSTEM CONTROL CIRCUIT under COMPUTERIZED ENGINE CONTROLS. If actuator valve does not operate properly, replace intake air control valve assembly. See INTAKE AIR CONTROL VALVE under AIR INDUCTION SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - V6 & V8 article.
