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.

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.

It's located aft of the cat converter under the middle of the van. Related Topics. Two Trip Fault. More than likely the sensor itself is bad but there's that chance the wire harness is damaged. Ignition on, engine not running. Sign up. Please consider creating a new thread. I could get in the habit of scanning for codes on a weekly basis to catch other issues. The back story is that the cat was clogged, so I replaced the cat, muffler and rear O2 sensor. My first fear was the cat was not doing a well enough job and the car knew it, but given the alarm I suspect that is not the case. The heater is used to quickly get the sensor up to operating temperature during engine warm up. You'll get varied opinions but I'm in the OEM camp for anything electrical. If you can use a meter you can check to see if the heater coil is open or there's no power to the heater. Chrysler Pacifica Luxury meets versatility in this mid-sized sport utility vehicle. One trip fault.

We recommend Torque Pro. Regardless of the number of oxygen sensors present in a vehicle, each sensor is provided with a dedicated circuit to control the heating of the sensor element.

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. Related Topics.

More than likely the sensor itself is bad but there's that chance the wire harness is damaged. Not a good Idea. It was a direct plug in, I will check the plug itself. Turbo84 85 Replies. 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. I could get in the habit of scanning for codes on a weekly basis to catch other issues. But ultimately I posted this question because I'm curious how to resolve the problem, and would prefer to fix it if possible. This code also came in when the cat was bad, but I thought that was from the damage.
