Xterra XE 4WD V6-3.3L SC (VG33ER) (2002)
Intake Air Temperature Sensor: Description and Operation
Component Description
The intake air temperature sensor is mounted to the air duct housing. The sensor detects intake air temperature and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in
response to the temperature rise.
Reference Data
CAUTION: Do not use ECM ground terminals when measuring input/ output voltage. Doing so may result in damage to the ECM's transistor. Use a
ground other than the ECM terminals, such as the ground.
