Whats going on with my truck? I Keep getting 0236@0237 I cycle the key erase the codes truck does fine for a day or so BOOM back on. Is the TST Boost fooling not good enough or is there something else wrong here? I have checked every plug on the truck everything is fine.Bumbs a person out The truck seems to run rough then smooth out back an fourth runs rough very long light comes on. PLEASE HELP.( I NEED NO MORE STRESS)

 

I don't know for sure if those are the same codes I get on a cold morning with the block heater plugged in all night. The codes I get are for battery temp sensor rationallity. It is a ongoing problem for some 06's. I had mine reflashed for the problem. Guess what, didn't help. If this is the same codes you are getting. I wouldn't be to alarmed by it. Mine only does it when it get's cold here in Idaho. It dosn't affect anything acording to my dealer.

 

This all started when it got cold here in INDIANA. I plug mine in to dont know if thats the problem or not but this sucks looking at the check light gets real OLD, truck stickers for allmost 49k shouldnt have that kind of problems. Maybe i should have kept my 05 least it was good!

 

the P0236 and P0237 are MAP sensor codes one for circuit high and one for circuit low(P0237). it sounds like something might be wrong with your TST. I would call them and ask.

 

I think your wright on this today i through P0336@P0237. Getting OLD i will pull it off and see what happens.Can i put the bypass on or do i need to remove the whole thing?

 

It would be wise to remove the whole thing. That way you know you are at square 1. It would "forsure" tell you if that was the problem.

 

I took the TST off what do you know fixed the problem. Im taken it back over Friday there switching me for a new one or somthing like that. Will try it again if that dont work i will get me a SMARTY and sell the TST BULLYDOG POWER PLAY MP8
