Where is IAT on a 2007 Lexus RX400h?

The Intake Air Temperature (IAT) sensor on a 2007 Lexus RX400h is typically located in the air intake duct, near the air filter box or the throttle body. It measures the temperature of the incoming air to help the engine control module optimize fuel injection and ignition timing. If you need to access it, you may need to remove some components for better visibility and reach.
