Just asking people for their experience on what this code resulted in. Seems it can be ac pressure switch, fan relay, fan itself or a fuse. I got this code 2 days ago after idling it for 30 mins while getting my daughter ready for school. Oddly, the car has never shown above 190 coolant temp since installing the mountune radiator and 160 degree thermostat. After I noticed I turned heat to full blast and drove it until I got the temp down. When I noticed it was at 240 so not engine killing temp but high and I got it down to 197 in 80 degree weather which is an okay temp for me. Since then, I cannot recreate it. Fan turns on at 210 but it should turn on when idling with ac on right? It does not do this until it hits 210 for me.
