| DETECTION CONDITION |
- During recovery from deceleration fuel cut, the HO2S voltage is 0.2 V or less, and the following condition is met:- When the elapsed time for the HO2S voltage to transition from 0.25 V to 0.45 V is greater than the specification 2 out of 3 times or more.
MONITORING CONDITIONS
- Drive Mode 03 (EGR System, A/F Sensor Heater, HO2S Heater, A/F Sensor, HO2S and TWC Repair Verification Drive Mode)
- Following conditions are met:
- During recovery from deceleration fuel cut
- Estimated temperature of the zirconia element inside the HO2S: above 450 °C {842 °F}
- Intake airflow amount: above 8 g/s {1 lb/min}
Diagnostic support note
- This is an intermittent monitor (A/F sensor, HO2S).
- The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
