OK my check engine light came on and I checked it out, it is the Barometric Pressure sensor in the EMC, what I need to know is what is what does this mean and, how do I fix it.

I have a JRSC and map controller if this makes a difference.

i know some people with the hack setup that get a CEL 13. it's a soft code right? meaning your driveability doesn't suffer? they just drive around with it. Resetting it may help for a few days, but it'll eventually pop up again. In their case, it's because of how extreme the adjustments are on the AFC and how touchy the OBDII ECU is. Not sure about your case.
