Air Temperature Sensor ( Ambient / Intake ): Specifications

Intake Air Sensor (688)

Intake Air Sensor (688):

Temperature sensor

Temperature Sensor:

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

Absolute pressure sensor

Absolute Pressure Sensor:

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

When checking pressure sensor with pressure/vacuum pump, a somewhat lower voltage may be obtained when measuring at high altitudes.
