Conditions for Setting the DTC

The PCM detects that the HO2S 2 did not transition below 300 mV and above 725 mV during the passive test.
One of the following tests fail:
- Lean Intrusive Test
  - The PCM detects that the HO2S 2 is more than 300 mV for 12 seconds.
  - The HO2S 1 is less than 300 mV.
    OR
- Rich Intrusive Test
  - The PCM detects that the HO2S 2 is less than 725 mV for 12 seconds.
  - The HO2S 1 is more than 600 mV.
DTC P2401 sets within 60 seconds when the above conditions are met.
