DTC P0153: O2 Circuit Slow Response (Bank 2, Sensor 1)
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2013 Lincoln Navigator, 2013 Lincoln MKZ, 2013 Lincoln MKX, 2013 Lincoln MKT, and 2013 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
DTC P0153: O2 CIRCUIT SLOW RESPONSE (BANK 2, SENSOR 1)
| Description: | The PCM monitors oxygen sensor response time by commanding a calibrated fuel control routine. This routine sets the air fuel ratio to a calibrated limit to produce a predictable oxygen sensor signal amplitude. For vehicles with universal heated oxygen sensors (HO2S), this DTC sets when the oxygen sensor signal does not reach the predicted amplitude within a predetermined response time. For vehicles with HO2S, this DTC sets when the oxygen sensor amplitude is less than the predicted minimum amplitude limit. | ||
| Possible Causes: |

||
| Diagnostic Aids: | Access the HO2S test results from the scan tool to verify the DTC. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST DZ . | ||
