The diagnostic code P0153 OBD2 indicates that the air/fuel ratio is not being adjusted correctly by the Oxygen Sensor O2 or by the ECM (Engine Control module), in the same way it may not respond to what is expected or that when the vehicle takes the normal temperature, it does not adjust to the expected frequency.
The Oxygen Sensor O2 is responsible for analyzing the oxygen in the atmosphere, the air that enters, must do so through the back of the sensor, ie between the wires. In situations where the sensor is contaminated by oil, there will be no airflow inside the sensor and so there are faults.
