In this case, the signal is higher than it should be. P should not be considered a breakdown risk.

There are three parts to the definition of P The first part is the malfunctioning part on your PT Cruiser, the second part indicates what is wrong, and the third part tells you where the malfunctioning HO2S is located. The heated oxygen sensor measures the exhaust after it exits the combustion chamber.
