Ambient Temperature Sensor: Description

Ambient air temperature is monitored by the Compass Temperature Mirror through a PCI databus message from the NGC engine controller. The ambient temperature sensor (Fig 1) is the source for the NGC engine controller. The sensor is a variable resistor mounted in front the radiator, behind the grille, near the left lower side of the radiator support assembly.
