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-.

Make sure that if this information is required by the PCM, it has been entered correctly to avoid a recurrence of the problem, p1684 chrysler.

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

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.

How do you troubleshoot code P? That should stop water, but fuel may not be able to get around the water to get pumped forward lean. Mopar-Mofun Replies. Hey Doug, My mileage was around 18 for teh tank with the E85, which seemed quite high to me. Since you said that you replaced the PCM a year ago, I would also be worried that you may have a bad one. P can be a glitch code at times as well. Disconnecting the battery to erase a code will set this code. All connections at top are good. Sienile Replies. The motor is likely sensing lean because some malfunction is causing it to run lean.

Some trouble codes are considered generic and the meaning is the same for most types of vehicles.

It's been driven quite a bit including on the freeway. My theory is that they simply have the voltage threshhold for tripping that code set slightly too high. Cheers Dean. Top list. If it's a newer battery, why not get it load tested first. For a better experience, please enable JavaScript in your browser before proceeding. ImperialCrown Replies. I don't know, what I have seen, is codes P or code 12 on vehicles with older but still seemingly well working battery's, then when replacing the battery, the code P and code 12's go away. For a better experience, please enable JavaScript in your browser before proceeding. It merely means that sometime in the last 50 starts of the engine, tha battery was disconnected. Please consider creating a new thread. Also, do you hear the fuel pump prime when you turn the key to "on" not start. Does anyone have some advice they could give me on how to trouble shoot what the exact problem is?
