Ok so...Will a severly dented tail pipe on a ford f150 supercrew cause a check engine light to come on? I have taken mine to 5 different shops and no one can figure out why the lights on.. I just noticed the tail pipe was bent the other day. I have no clue what to do now. Its a 2004 and the only reason it will not pass smog is the stupid light. PLEASE HELP ME

 

What is the code that is causing the light to come on? Need exact number.

 

Maybe there's a crack or leak of some sort just before the cat. How did the pipe bend?

 

The pipe bent from the back to the passenger side of the truck pinching the pipe making it a 90 degree angle. But wouldnt the people at the smog shop stick something in the pipe itself? Correction ( the pipe is more bent to the front end close to the tire.
