Conditions for Setting the DTC

1. The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 did not transition below 350 mV and above 709 mV during the passive test.
2. One of the following tests fail:

   Lean Intrusive Test

   • The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 is more than 350 mV for 60 seconds.
   • The HO2S bank 1 sensor 1 and HO2S bank 2 sensor 1 is less than 300 mV.

Rich Intrusive Test

• The PCM detects that the HO2S bank 1 sensor 2 or HO2S bank 2 sensor 2 is less than 709 mV for 60 seconds.
• The HO2S bank 1 sensor 1 and HO2S bank 2 sensor 1 is more than 600 mV.
