Keep the outside-temperature reading and automatic climate control working correctly with the Standard Ignition Ambient Air Temperature Sensor AX238. It installs as a direct-fit replacement for the 2006-2008 Lexus RX400h, dropping in for the original sensor without guesswork.
An ambient air temperature sensor measures the temperature of the outside air and sends that signal to the vehicle's climate control system and instrument display. When the original sensor drifts or fails, the reading can read inaccurately and the automatic climate control may respond to a false temperature.
