P013A - O2 SENSOR SLOW RESPONSE - RICH TO LEAN (BANK 1, SENSOR 2) - DTC CHART
| Description: The heated oxygen sensor (HO2S) monitor tracks the rate of voltage change during the rise and fall of the heated oxygen sensor bank 1, sensor 2 (HO2S12) signal. The measured rate of the rich to lean switch is compared to a calibrated fault threshold value. The threshold value takes into account the level of oxygen in the catalyst, which has an impact on how quickly the rich to lean switch occurs. This DTC sets when the measured value is slower than the threshold value. | |||
