02 Sensor Circuit Slow Response (Bank 2 Sensor 1)
The P0153 trouble code is an indication that the oxygen sensor is not properly regulating the fuel and oxygen levels. The oxygen sensor voltage switches between high voltage (fuel) and low voltage (air) at a rapid rate of speed.
When the oxygen sensor switches at a speed that is slower than normal, it causes a slow response between the oxygen sensor and the power control module (PCM).
Two symptoms that are most commonly associated with the P0153 trouble code are:
The mistake that is most commonly made when diagnosing the P0153 trouble code is that the oxygen sensor is replaced without first inspecting the other components of the system. Replacing the oxygen sensor won’t fix the problem or clear the P0153 trouble code if there is an issue somewhere else that is causing the error code, such as a leak in the exhaust or intake.
It is not a serious code. The car will use more fuel but it should not cause any more problems that that.
It some rare cases, and over a long period of time, this code could affect the performance of the catalytic converter.
In most cases, this repair will require specialized tools. The oxygen sensor commonly ceases up in the exhaust pipe and when this happens, an oxygen sensor tool and a heating agent will be necessary to complete the repair.
