P0206 When TST is Installed

775 Views 7 Replies 3 Participants Last post by  Austin The DieselTech
I installed my TST tonite and when I started it the CEL comes on and my Smarty reads a P0206 which is Injector #6 Control Circuit.:CRY: I checked my connection and nothing changes. So I pulled the TST and harnesses and it runs normal. The injector harness I was using was brand new from TST. Could this harness be bad??? Thanks.

are you sure your tst is good? maybe not reading right through the box... just my opinion since it runs fine when the box isnt in it...
id try the other harness, if the same id send the module back... sorry to hear
