P0455 code fixed, or not likely?
From : jmc
Q: suddenly without warning mike simmons exclaimed 7/31/2007 750 pm just wondering if its possible that it was actually the muffler that was causing the codes and if someone could explain why. twig said he thought it was unlikely that the system could sense that far down the system to throw this code because of a muffler problem. the exhaust system will not cause that code. the check engine light will i fear return. your truck is equipped with an obd ii diagnostic system that performs periodic self tests. after three good self tests the check engine light will turn itself off. thus if the problem was no longer there the light would have self extinguished by now. sorry to be the bearer of bad tidings. mike waaaaah! now look youve gone and made me cry! i was hoping though but i know that ive had the code for a lot longer than the seriously rusty muffler. how often does it run these self-tests so youre saying i shouldnt reboot my truck after its fixed i should wait and see if the code goes away on its own jmc .
