Outside Temperature Display Sensor: Description and Operation
Description
DESCRIPTION
Ambient air temperature is monitored by the overhead console through ambient temperature messages received from the Powertrain Control Module
(PCM) over the Programmable Communications Interface (PCI) data bus circuit. The PCM receives a hard wired input from the ambient temperature
sensor. The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the headlamp mounting
module grille opening, behind the radiator grille and in front of the engine compartment.
