Ambient Temperature Sensor
WARNING: This page is about a different car, the 2003 Chrysler Concorde, 2003 Chrysler 300M, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Ambient air temperature is monitored by the EVIC through ambient temperature messages received from the BCM over the PCI data bus network. The BCM receives a hard wired input from the ambient temperature sensor. See Figure . The ambient temperature sensor is a variable resistor mounted to a bracket that is secured with a screw to the right side of the headlight mounting module grille opening, behind the radiator grille and in front of the engine compartment. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
