Bad cat bay 2 code,

i have an 05 taco with 145k just bought the vehicle last week got a code for a bad cat in bay 2,
I need some advice on how to move forward. Do nothing? Replace O2 sensors? Replace cat? Is OEM a must? thanks

 

If I got a bad cat, I probably would just get long tube headers & O2 sims. May not be an option where you live though.


Maybe reset, (unplug battery for awhile) and see if it comes back.

 

i reset the code, and drove for 100 miles so far with no issues so far. I live in NY im not sure if i can get away with that here in NY.

 

Cat might be just fine.

 

?

Would be an easy sell to the wife, cats bad gotta replace with headers!

 

Shore.

But code saying bad cat doesn't mean bad cat.

 

Hence second part of statement, which he's already reset. But yes, could be bad O2, exhaust leak (bad reading) etc...

 

im thinking of running some sea-foam through the vacuum line and using it as a smoke test to check for leaks. Any one know what OEM O2 sesors would run me?

 

Check rockauto. They give a TW discount.

 

well, crap. nice to know that now lol.. Ive ordered a lot from them

 

I think it's 5%, maybe 10.

They have their own subforum if you click the Forums tab up top.
