Air Temperature Sensor ( Ambient / Intake ): Specifications

Intake Air Sensor (688)










Temperature Sensor







Power supply 5 V through 2.74 kohm resistor in control module.


Absolute pressure sensor







Pressure specified in kPa refers to absolute pressure, i.e. 100 kPa corresponds to atmospheric pressure at sea level.

When checking the pressure sensor with a pressure/vacuum pump, slightly lower voltages may be obtained at high altitudes.
