I replaced the EGR with a used unit and that one went away. I inspected the downstream O2 sensor located on the cat and saw that it had broken wire.

With that being said, the code refers to a fault or problem in the heating control circuits of the O2 sensor HO2S. This code is closely related to P which is an error caused by a low circuit. On the other hand, P is a circuit high input code. Take note that most problems associated with high input codes are related to excessive voltages in the system or faulty alternators. In most cases, the check engine light is triggered by the O2 sensor due to short circuits in the vehicle charging system. Most of the time, the problem has nothing to do with broken or faulty heated oxygen sensors. The P code is most likely caused by faulty or burnt wiring, which has nothing to do with the sensor per se. Since the O2 sensor and related wiring are located close to the exhaust, it is not uncommon for the wiring to burn or wear out, most especially on older vehicles. Bad wiring and bad ground connections can cause a variety of short circuits in the system, which will also trigger the check engine light.

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 Town and Country, 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.

Quote message in reply? So I replaced the sensor with a new NTK unit and cleared the codes. Does the voltage stay above 4. The replacement cat was not OEM, but it was a direct fit replacement.

It's located aft of the cat converter under the middle of the van. It should be repaired because the heaters heat the o2 sensors faster bringing them into closed loop for better fuel economy fewer imissions and not so hard on the converter. Hello all, NTK O2 sensor has 4.

In this case, the signal is higher than it should be.

But codes P and P came back and will not go away. Posting Quick Reply - Please Wait. Insert Quotes Quotes Post Reply.

Raising the hood may help in reducing under hood temps. Cheers, Andrew. Sort by Oldest first Oldest first Newest first Most reactions. Will check the owners manual but additional guidance is appreciated. More than likely the sensor itself is bad but there's that chance the wire harness is damaged. What I failed to mention is that after I replaced the parts my wife drove for 2 days before it came back, maybe miles tops. It should be repaired because the heaters heat the o2 sensors faster bringing them into closed loop for better fuel economy fewer imissions and not so hard on the converter.
