I'm throwing p0606 and p0336 could these becasue by a problem w/ tst?

 

ssleeper94, This post should be in performance and accessories but the answer is yes. Check the TST website, FAQ's or troubleshooting. Is the unit brand new? Most problems with the TST are in the wiring harnesses or with the ground location. Sometimes the ground must be moved from the - terminal on the battery to the metal ground under the dash. Best advice is to switch post to correct spot so that everyone can get their advice to you and check the tst website. Do a search on here for those codes. KS

 

There is nothing wrong with your TST, they throw codes in some trucks in certain conditions.
606 is an internal ECM code, the ECM is seeing something is not right(TST) but no CEL with it. I have been told it is related to the ground for the TST as was said before.
336 is a crankshaft performance rationality code, Mine does it once in a while with a CEL that resets after a while. Last time it set I drove thru some large water puddles and it came on. I cleaned the connections and put dielectric grease on it and haven't had one since.

 

I have an 04 305hp with a TST and I also get both those codes, after a few key cycles, the light goes out. I think I'll try the ground relocation though, hadn't heard about that.

 

how do you know your throwing codes, i know how to check for them. Does your check engine light come on? or what

 

My check engine lamp does go on intermittantly, and stays on for 8-10 key cycles, then goes out. Always the same 2 codes, take it to my buddies shop and clear them out, wait til it happens again. The only good thing is it makes a good excuse to get together and drink beer, thanks TST.
