Thread Tools. Looking to find out what the code Pis for, I'm guessing something to do with my ABS light that cameon. I've checked the fuses, wire bunldes going to all speed sensors. I think from here on out it gets expensive. Any ideas? View Public Profile. Find all posts by Burkett

We recommend Torque Pro. One unfortunate consequence of this is that many generic code readers are sometimes not programmed with all the definitions in use for a particular P1XXX code, and in the case of P, there is a lot of confusion about which definition of this code relates to which manufacturer. Note though that there are still other definitions of code P in current use, and some information on these definitions can be found in the Related Codes section of this guide. What this definition really means is that any problem or circumstance that causes full system battery voltage to be lost, or not to be available to any part of the electrical system or control module, can set this code. In many cases, the presence of code P on Chrysler, Dodge, Jeep, or Plymouth applications means nothing more than an indication that either the battery was disconnected within the last 50 starts, or that system power had been lost for some reason during the last 50 starts. Moreover, the code will usually, but not always, be automatically reset, or cleared by the PCM if the code does not occur again within the 50 start-ups following the start-up event during which the code was set. Refer to the manual for the application being worked on for detailed information on all possible causes of this code for that particular application. The most common symptom of P on affected applications is the presence of a stored trouble code, and an illuminated warning light. However, the immediate absence of serious symptoms, which could include driveability problems, should NOT be taken as an indication that no damage to the system had occurred, since some symptoms can take a while to manifest. As stated previously, the battery does not have to physically disconnected for this code to set, but since the affects of losing power to the system can and often does produce erratic, unpredictable, and often-confusing symptoms, many mechanics including professional technicians often fail to make the connection between the loss of system power, and the sometimes-bewildering array of symptoms and additional fault codes that can come with this code, especially when the battery has not been replaced in the recent past. Below are details of some symptoms that may, or may not, be present with code P, but note that this list is not exhaustive. Refer to the manual for the application being worked for detailed information on all possible symptoms that could affect that particular application-. Typical values include fuel trim settings, transmission shift points, and all other settings that are adaptive. Moreover, the KAM chip also contains all fault codes ever stored, all their accompanying freeze frame data, and the results of all self-tests the PCM had ever run on the emission control system. Thus, if the problem that set code P is not resolved, the code will be set again, and although it may take a day or two, the code will return, along with all the additional codes and driveability issues that were present originally.

There are many codes that may appear on an OBD2 scanner, but the code P is one of the most common ones you may spot for your car. Upon the first symptoms of the code and reading it on a scanner tool, you may assume it has something to do with the electrical system of the car, but what about the true P code meaning? To help you figure out all the important implications of the code, we decided to give you a tour through this comprehensive guide. Find out more about OBD2 codes research process. The P code is a diagnostic trouble code that is related to the battery. Specifically, this code indicates that the battery has been disconnected within the past 50 engine starts. Additionally, if this code is not addressed, it can cause the vehicle to fail an emissions test. There are several potential causes of the P code. One of the most common causes is a battery that has been disconnected or replaced recently.

Some trouble codes are considered generic and the meaning is the same for most types of vehicles. Other codes can be specific to the manufacturer, such as the P code. In this guide, we look closer at the meaning of the P trouble code and determine what fixes work out the best. We also touch on the symptoms, approximate repair cost and talk about how to diagnose the problem.

It does sound like it was ultimately an issue with the E Your refurbished PCM is 15 years old and subject to the same failure as others. Being a 99 my guess is the battery cables are probably getting pretty slim by the clamps. This site uses Akismet to reduce spam. If there are other codes present along with P, it is likely that these codes are the result of P, rather than its cause. AVS Forum. Depending on how much your mileage drops, it may be cheaper for you to burn E The factory diag sheet for P is for battery disconnect. Your battery may be showing a little age, but if you had no electric or battery problems up to this point, it probably is meeting your needs just fine and you're getting that nuisance P like many Chrysler owners do.

I have the code for years, always started reliably, when the battery finally gave out and I put in a new battery the code went away. Will the disconnect reset my ECM and my check engine light every time? View Public Profile. Just clear the codes you can and see what happens. I understand that this is not a DTC something about the battery being disconnected or something but the car is in "limp home mode" and I don't know what to check? But it's now almost June and it hasn't gone away. Please consider creating a new thread. Cheers Dean. I could swear I read you should be near empty when switching from one fuel to the other, but I'm not sure. The only time I got that code on a consistent basis on one of my Concordes, I would reset it, and 9 times out of 10 when I started the car the next day and it would start fine , that code would appear and the time on the radio display would reset. That's the most common source of P This is not a problem. The factory diag sheet for P is for battery disconnect. Clear the codes and see what happens.
