Last Friday was one of those days. Nothing seemed to change at all with the driveability, even after doing numerous stops over a mile total day. No issues at all However, the next morning, it was difficult to start, popping and not starting numerous times before it finally just ran normally all of my 3. It ran fine all day without issue. I checked the code and it was P Power loss to one of the "CM's" OR something major?? Again the next morning, difficult to start, driving normally.

P saying there is a memory error and P indicates the multiple power loss, p1684 chrysler, but p1684 chrysler also indicate a communication malfunction within the PCM. 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?

I did the on-off-on-off-on key-dance, and it displayed P and P The P is an old friend -- our former Voyager used to just about always have that one stored. The P indicates a failing PCM, but it can also be caused by a low battery, and the battery is at least 5 years old.

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. The P DTC indicates that the car battery was disconnected within the last 50 starts. The Powertrain Control Module PCM is responsible for monitoring the charging system and it sets this code when the battery was disconnected or there was a lack of voltage within the past 50 starts.

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.

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.

It means that there has been a power interruption to the TCM transmission control module as dun4now has pointed out in Post 2. Join now! I've started it like times now and 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.
