This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it. It is a general term that usually implies that the heating element circuit of the HO2S has a problem. In modern vehicle engines, oxygen sensors with a heating element are widespread. A heating element is crucial to this sensor. Whilst an oxygen sensor was a single wire sensor in pre-OBDII cars; now a four wires sensor is more common. Two wires dedicated to the oxygen sensor and two dedicated to the heating element. The oxygen sensor warmer simply reduces the time required for a complete loop.

In this case, the signal is higher than it should be. P should not be considered a breakdown risk. The HO2S in question is downstream of the catalytic converter and is mainly just for emissions purposes. There are three parts to the definition of P The first part is the malfunctioning part on your Ram, 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. The PCM uses this data to maintain the proper This reduces emissions by letting the fuel trim enter closed loop operation more quickly.
