P0153 - O2 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
| Description: | The PCM monitors the universal heated oxygen sensor bank 2, sensor 1 (HO2S21) response time by commanding a calibrated fuel control routine. This routine sets the air to fuel ratio to a calibrated limit to produce a predictable oxygen sensor signal amplitude. This DTC sets when the oxygen sensor signal does not reach the predicted amplitude within a predetermined response time. | ||
