I just got my dash back together after replacing the blend door moter in my 99 and the service engine light came on reading code 0740 (torque converter). I know that I'm going to have to take the blazer in to a mechanic to fix this being it's beyond my talents plus I'm burnt out after the blend door issue but I do have a question: I am due for an emissions test soon. Will the code 0740 popping up cause me to fail the test? I would like to know this so I know how soon to get the 0740 problem repaired. please help.

 

Depends on your state, in Texas absolutely will fail.

 

^X2^ i know that if you have a CEL on you will fail the inspection in New York.

 

I,m in Illinois so I'll just assume that they will fail me. Oh well, no vacation for the family this year.
