(1) While pressing Transmission Control Switch or switching to manual drive mode.
(2) Downstream O2S(s) will stay close to a constant voltage when catalyst monitor is off (positive value only). When catalyst monitor is on, O2S will switch rich to lean above and below .45 volt DC and never be a negative value.
(3) Value is dependent upon ambient air temperature and may fall outside of range.
(4) A/C on.
(5) O2S should switch from rich to lean at least once every 3 seconds. O2S voltage should toggle above and below .45 volt DC and never be a negative value. Valid O2S switching only occurs during closed loop fuel control.
(6) Brake pedal applied.
(7) Value is not useful under this condition.
