P0140 - Fast Pass Test

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. 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 381-525 mV and less than 180 samples within the first 90 seconds of engine run time. If the fast pass test does not report a pass, then the regular test is initiated.
