WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The DTC will set when the BCM detects that the change in voltage of the driver temperature sensor signal circuit is either to slow or to fast.
