Description

DESCRIPTION





Ambient air temperature is monitored by the Electronic Overhead Module (EOM) through ambient temperature sensor messages received from the Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data bus network. The PCM receives a hard wired input from the ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted in front the radiator, behind the grille, near the center of the vehicle.

Refer to Powertrain Control Module (PCM) in Electronic Control Modules. For complete circuit diagrams, refer to the Wiring information. The ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
