Archived Limp mode, then not

[LTustison]

I have been having limp mode on and off for a week or so now. It seemed to be temp related, but today it seemed to be limping even sooner than before. I erased the codes and it was limp all the time. Then, on the way home the check engine light came on and it was out of limp mode. the codes were 234,234,236. I think it is the boost sensor, because the boost has never been over 18. 5, but code says overboost. Any other possible scenarios? I am getting a new boost sensor tomorrow Sure hope it works.

Well, i didn't get any response, so today i installed a new boost sensor, erased codes before starting and all is well, so far. Time will tell, but i think this was it
