P0140 - Fast Pass Test

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.

During the fast pass, the HO2S 2 voltage is between 350-550 mV for longer than a calibrated amount of time within the first 75 seconds of engine run time. If the fast pass test does not report a pass, then the regular test is initiated.
