Intake Air Temperature (IAT)

Range (-40 to 151°C -40 to 303°F)
The VCM converts the signal voltage of the Intake Air Temperature (IAT) sensor into degrees. The VCM uses the intake air temperature in order to adjust fuel delivery and spark timing according to the incoming air temperature.

(0-5 Volts)
The VCM monitors the intake Air Temperature (IAT) sensor for voltage changes. This parameter displays the raw voltage signal detected by the VCM. The VCM uses the intake air temperature in order to adjust fuel delivery and spark timing according to the incoming air temperature.
