Conditions for Setting the DTC

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The PCM detects that the HO2S 2 voltage remains within 74 mV of the bias voltage, about 450 mV, for a longer amount of time than necessary. The amount of time ranges between 100-280 seconds depending on ECT at startup, and the average mass air flow (MAF) since startup.
