the TPS seems to be failing quite a bit on the JK. I think that will be a quick and painless warranty deal
EDIT: oh and to answer the what does it mean...the TPS has multiple refrences that they use. It is different on some vehicles but I belive the Jeep has three refrences that it compares. That code is saying that the refrence from TPS 1 and 2 are not in line with each other indicating something is off somewhere. I am guessing it is a faulty code as I have seen the TPS fail so often on the JK.
YOu may want to take a look at your airfilter though. Is it been replaced recently? Do you use a K&N filter? If so, you may want to check the air flow sensor and be sure there is no oil on it. That is going out on a limb a bit as I still say the issue is just a bad TPS. Normally if there was another issue that would trip the TPS CEL there would be another code thrown. Was that the only code?
