BOOST AIR TEMPERATURE SENSOR [SKYACTIV-G 2.5T]
id0140h0256400
Purpose
• The boost air temperature sensor detects the charged intake air temperature after it passes through the charge air cooler mainly as basic information for boost control.
Function
• Detects the charged intake air temperature after it passes through the charge air cooler and sends an intake air temperature signal to the PCM.
Boost air temperature sensor characteristic
Construction
• The boost air temperature sensor is integrated with the boost pressure sensor.
• A thermistor has been adopted for the detection part of the boost air temperature sensor.
• A thermistor is a resistor element in which changes in the electrical resistance is large against temperature change. Using this characteristic, the sensor detects the intake air temperature as a resistance value.
Operation
1. The boost air temperature sensor detects (1) the intake air temperature.
2. The PCM detects (2) the intake air temperature based on the voltage from the boost air temperature sensor.
Fail-safe
• Not applicable
