| DETECTION CONDITION |
- The PCM monitors the voltage between PCM terminal 2AD and 2AC while the A/F sensor active. If the voltage deviate from specified range, the PCM determines that there is a A/F sensor circuit problem.
Diagnostic support note
- This is an intermittent monitor (A/F sensor, HO2S).
- The MIL 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 the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
