In Dynamic Chamber

Intake Air Thermosensor:

The Intake Air Thermosensor, located in the intake air system dynamic chamber, detects intake air temperature. The ECU uses this input in its calculations for idle speed and pressure regulator control. Sensor resistance and the voltage signal to the ECU vary with intake air temperature.

Sensor resistance measurements are as follows:

K OHMS AIR TEMP.

37.3 - 45.6 20°C / 68°F
10.5 - 12.9 50°C / 122°F
3.1 - 3.8 85°C / 185°F
