Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. P Tech Notes As the code description implies the P code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly is not as efficient as the factory is expecting.

Replacing the oxygen O2 sensors may sometimes fix the code, but in most cases, the catalytic convert needs to be replaced to fix the problem. If the P code is combined with other codes, try fixing the other codes first.

When is the P code detected? A three way catalyst converter Manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed.

Your Pathfinder has at least two oxygen sensors, one before and after the catalytic converter.

Among the many jobs that oxygen sensors have is they measure the emissions levels before and after the exhaust gasses enter the converter. P means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading. The upstream and downstream oxygen sensors should show different readings. The computer wants to see that the catalytic converter has scrubbed exhaust emissions. See Also: P Nissan Pathfinder. For most people the first sign that anything is wrong at all is the service engine soon light coming on.

Oxygen Sensor — The P codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged. O2 Sensor Wiring — Over time, the oxygen sensor wiring can go bad. It is especially volatile since it is right next to the hot exhaust at all times.

The downstream oxygen sensor wiring is especially volatile since it is so far from the ECM more distance to travel.

Timing — If your Pathfinder is misfiring or the exhaust timing is off, this can affect the gasses that are actually going to the O2 sensors enough to cause the P code to register. When the fuel mixture is rich, the exhaust the O2 sensors see will be out of range and it could throw PThe function of the catalytic converter is to break down harmful pollutants that are created by your vehicle during the combustion cycle and convert them into less harmful gases.

Code P indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle. While P does not pose a danger to the driver, it can cause driveability concerns such as a lack of power or poor acceleration if left unrepaired. It can also cause severe damage to other components of your vehicle if not addressed in a timely manner.

It is recommended that you address P as soon as possible to keep the cost of the repair to a minimum. Do not overlook other codes that are paired along with P If the catalytic converter is replaced without repairing the misfire, the new catalytic converter will go bad again.

If these codes or any other codes are present, they should be addressed first. For error code P, one or more of the below repairs may be needed to solve the underlying issue.

For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair. Download The Savvy Motorist Report now to discover:. My car is not displaying any of the PO symptoms. I just had a tune up on my ford edge and next day engine light came on and P code registered on my fixd. Is it coincidence?

The consistency of your voltage reading means that your downstream O2 sensor is operating correctly. My Downstream O2 Sensor voltage reading is a consistent.
