The Ambient Temperature Sensor of the Lexus LS400 immediately provides outside-air data to the luxury sedan so it can automatically adjust cabin comfort and engine response without any driver input. This Ambient Temperature Sensor is located at the front, in unobstructed airflow. The sensor's resistance changes with every breeze, sending a clean voltage signal to the climate computer and powertrain computer. With the help of this information, the LS400 adjusts the blower speed, the blend doors, the fuel mix, and the ignition timing so that Lexus occupants enjoy steady, comfortable temperatures while the V8 remains eager and efficient. One rugged Ambient Temperature Sensor design serves every first and second generation LS400. Lexus' commitment to simplicity and durability means that every temperature sensor can be applied with every design. The Ambient Temperature Sensor continuously samples the air so that the climate control does not respond late to suddenly rain-cooled gusts or to hot sunlight. When the roads are possibly icing over, systems use the Ambient Temperature Sensor to warn the driver, improving safety. The LS400 utilizes its readings to maintain traction while giving reassurance to Lexus passengers. An enclosed housing that resists road grime, vibration, and moisture means you seldom need to think about the Ambient Temperature Sensor. You can simply plug it in, thanks to the Lexus factory connectors, and there shouldn't be any need for recalibration either. That's the case in any LS400 built between 1989 and 1998. Also, drivers appreciate that because it's precise, the Ambient Temperature Sensor prevents wasted fuel by avoiding overcooling or overheating cycles. So, not only is the LS400 economical, it's comfortable too. Plus, those attributes give you another reason to celebrate the legendary quality of Lexus. The ability to anticipate future events reduces the wear and tear of mechanical parts, allowing for a calm and enjoyable long trip for everyone on board the vehicle.
