where is it located in my engine and how much is it ? i need the dumbass thing to pass smog .I spent 50 bucks for nothing today .
i was talked into buying a cat and a o2 sensor 250 for both and i still cant pass smog.

leak detection sensor for what? like for the evap. emissions or something? thats the only thing i can think of that would give a CEL refering to a leak.

If you have a good condition catalytic converter and new o2 sensors, how could you not pass emissions? What mods are you running? You sure the guys who sold you the cat didnt screw you over?

The only leak detection sensor I know of is up near the fuel tank. I had to have mine replaced and they had to take the whole fuel tank out. Not sure if it's what you are looking for and don't know how it would make you fail smog either.
