    Strange Codes Thrown, Limp Mode....

    My car is an 07 FBO 335 with secondary cats and stock mufflers

    I upated to the latest JB4 Interface software and firmware Thursday night and went out and filled up with 93 and a 40% mix of E85. I also changed the Future Use D setting to 99 to try to quiet down my WGs. Car ran very good Thursday night

    Friday morning, started up and went right in to a CEL. Pulled the code and it was a 2ABD Intake pressure sensor, re-running. Cleared it and restarted. Car ran fine rest of the day.

    Saturday morning, started up very odd and ran poorly almost got stranded and got a CEL and limp mode. Went back and pulled codes and got the following:
    2ABC Charging Pressure Sensor Electrical
    3100 Low Boost Mode Engaged CEL


    Also, I cannot clear these last two codes with the JB4 software interface. This is troublesome.

    Do you think any of what I did Thursday night (firmware, E85 or WGs adjustment) could have caused this?

    The car ran fine prior to this no issues at all and I regularly update my firmware.

    Any thoughts? Anyone had the same thing and know the reason this may be happening?

    Thanks

    Sounds like sensor or wiring.

    I was able to clear the codes today and then take out the airbox and cowl to look at the TMap sensor. Everything was connected fine, so I moved to check the JB4 connections and everything was good as well.
    Put everything back together and fired it up two different times and everything was fine. Ran perfectly smooth, but was not able to drive it due to hard rain in the area.
    Not sure what the problem was, but I willl be keeping an eye on the car the next few days.

    Any idea why?

    You can clear them now after taking off the airbox and putting it back on?

    I could not clear them after repeated efforts on Saturday, but Sunday I was able to clear them. I did research on the 2ABC code Saturday and saw that others (albeit 2009 or later) could not clear that code as well.

    I don't think removing the air box or the TMap sensor had anything to do with clearing the code. Might have been a "time" issue.
