    ...which is Barametric Pressure.

    What does this do/mean?

    Is it a something to worry about?

    Thanks.

    P0129 - BAROMETRIC PRESSURE OUT-OF-RANGE

    What'd you do?! :blink:

    No, seriously, have you done anything under the hood? P0129 is caused by a bad MAP sensor or vacuum leak. Check any hoses in or near where you worked under hood, just for starters. :erm:

    But, this is coming from me. What do I know. :cry:

    it means that in a perfect world (sea level, 50degrees, straight line)if your shooting an m855 5.56mm round every incriment your barometric pressure rises then the strike of your round will impact 1" higher at 100 yards and for every drop in the BP your round will strike 1" lower at 100yds which means a change of 1 minute of angle (MOA)

    hmm Must have been a hiccup in the MAP Sensor? I also got a P0300 which is a Random Engine misfire. Cleared the PCM and all is well. lol So far. Yea, I checked all of my vacuum lines. All ok.


    lol Ah, the memories of my Army days. hehe Back in the day, I could knock a crab off of MoMo's pecker (and we ALL know how small that is) from 300 meters with my M16A2.

    How's the MAP effected by the blower? You didn't change the pulley did you? or get some crap on the underside of the belt?

    Map sensor or vacuum leak.

    Did you start your car with the MAP sensor disconnected?

    Nothing was changed or touched since we did the Direct Port Tune while in SoCal... Over 1100 miles before the hiccup.
    No sir.

    Do you have a blower on this car?
    I would guess if the code has not come back that it was just a weird issue...

    Yes Mike, I have a blower on the beast. I am also running 12psi.

    What was odd was that not only did I get the P0129 Code, I also got a P0300 code.

    After I reset the PCM, I have been good.

    I also talked with Scott (GSM) last night and he will relook at my tune to see if a few settings were mistakenly added to my tune.

    Thanks for the response and I hope you had a nice Easter Sunday with the family.

    WOW P0300 multiple misfire codes and your probably the first EVER to get the P0129 thanks for being the innovator.

    Only thing I could find from Chrysler and turbo was realted to the SRT4 and the P0129 is basically labled as an erroneous code that might need a PCM reflash to remove it

    NOTE: DUE TO THE PCM REPROGRAMMING PROCEDURE, A DTC MAY BE
    SET IN OTHER MODULES (TCM, BCM, MIC, SKIM, ETC.) WITHIN THE VEHICLE,
    IF SO EQUIPPED. SOME DTC’S MAY CAUSE THE MIL TO ILLUMINATE. ALL
    DTC’S RELATE TO A LOSS OF COMMUNICATIONS WITH THE MODULE
    THAT IS BEING REPROGRAMMED. CHECK ALL MODULES, RECORD THE
    FAULTS, AND ERASE THESE FAULTS PRIOR TO RETURNING THE VEHICLE
    TO THE CUSTOMER. ERASE ANY FAULTS IN THE PCM ONLY AFTER ALL
    OTHER MODULES HAVE HAD THEIR FAULTS ERASED.
    .

    oh and here is a GOOD list to keep somewhere
    http://www.wjjeeps.com/faultcodes.htm

    here is yours exlpained
    P0129
    Barometic Pressure Out-of-Range low
    MAP sensor input voltage out of an acceptable range detected during reading of barometric pressure.
    more proof that weather plays a factor in performance

    Ron was this on a cold start?the 0300 could have been caused by a cold start stumble triggering the 0129.

    No. we had been driving around for nearly two hours. I was at a stop light waiting to turn left when I went into Limp mode.

    I pulled over, turned car off, restarted, put it into "D" and it would stall. Did this 8 times before it finally did not stall. Made it home pulled the codes, cleared via Predator. Restarted, still stalled.

    Next morning I pulled the fuses and cleared the PCM and all has been fine. :shrugs:
