I have an 06 with the 2.0L engine. The heat did not blow real hot so I did the odometer test mode which read a max of 70C and did not appear to cycle the temp up \/ down indicating the thermostat opening and closing. I replaced the thermostat and now I have great heat! However, running the odometer test mode, now I read up to 108 C and the temperature does still not cycle the temp up and down. The outside air temp was cold, at 30 F. Is 108 C on the CHT sensor cause for concern? The temp gage on the dash is reading near center before and after thermostat change.
