Hello,

That is a 5ECD and GM46362 is correct.
CO6: Fault code is displayed if the CO sensor is inoperative.
This is normally just a sensor replacement. The sensor should be replaces every 2 years per the maintenance schedule.

Accepted Answer

The CO sensor GM46362 (printed circuit board) is located on the back of the ADC controller. CO3 is a communications fault between the ADC and CO sensor. If the sensor harness is there and the controller has the mounting spot for the sensor, it must be installed or the unit will shut down. The CO sensor should be replaced every 2 years per the service schedule to prevent failures.
