My ambient air temperature gauge was giving bad readings by about +/- 15°F yesterday, then I got the “Grille Shutter Inoperative” dashboard message. Does anyone know if the active grille shutter system uses the ambient air temperature as an input for the controller? I don’t see any obvious obstructions or damage to the shutter system.
Yes, it's monitoring ambient temp for it's operation. If it's cold enough in winter, it'll purposely leave the shutters inoperative and partway open.
Ok, thanks so much for the quick reply! So I wonder if my ambient temperature sensor is giving some out of bounds signal, and the active grille shutter system went into some sort of safety mode. The shutters are open, but I haven’t really evaluated whether they’re 100% open or more like 75% open.
Excellent information! Thank you guys so much! Now the big problem is that I’m on the road 900 miles from home and 500 from my destination with hardly any tools.
Trying to read the grill shutter operation pdf, is there any precedence to the operation? For example, if I'm driving at 70 km/h and it's 38C outside, what will the shutter position be?
I don’t think the message will be a problem. I’m just worried that the shutters aren’t totally open while I drive through the middle of nowhere in triple digit heat.
