Hitachi® TMS0003 - Air Charge Temperature Sensor

Modern vehicles incorporate a variety of sensors that are used by control systems to deliver maximum performance. An air charge temperature sensor is responsible for measuring the temperature of the air entering the engine. This information is required by the computer to determine air/fuel mixture, spark timing, and idle control. At cool air temperatures the air density is higher and the engine needs more fuel to compensate, and vice versa at high air temperatures.

A malfunctioning air charge temperature sensor affects vehicle operation, causing the engine to run rich or lean, which in turn can cause rough idle, hesitation, poor fuel economy, misfire and detonation, and increased emissions. If your sensor has failed due to constant exposure to the underhood heat, debris, or age, get a reliable replacement from Hitachi, a globally recognized original equipment manufacturer. Hitachi uses the latest electronic-sensing and control technologies to make sure their sensors are superior to the competition. Improvements in sensor accuracy lead directly to better control system performance. This sensor will restore optimal operation of your vehicle, providing accurate air temperature readings.
