WebThe P0153 trouble code indicates that the upstream O2 sensor on Bank 2 is not properly regulating the fuel and oxygen levels. The O2 sensor voltage switches between high voltage (fuel) and low voltage (air) at a quick rate of speed. If the O2 sensor is switching slower than normal, the response between the PCM and the O2 sensor will be slow. WebThe P0300 engine code indicates a misfiring cylinder problem in your vehicle.
