Ok... so heres the deal. Have had test pipes on my car since 11'. Since theyll throw a code anyways i ended up removing the o2 sensors completely cause the angle they go in and with how low my car is they would scrape the ground. Well i capped off the harness connections and zip tied them to be safe and out of the way.

Well reinstalled my cats with some brand new o2 sensors from rock auto about a month ago. Deleted the code and reset the ecu. Buuuut after about 20 min of driving it comes back and stays on and i need to get emissions soon.

Anyone have any idea what i can do to fix this? Dont any crazy mods either. Intake plenum and injen cat back exhaust at the moment.

 

Cats are probably shot.

 

there is no way they are. They worked perfectly before i pulled them in 2011 and put them into a box and didnt touch them again till i put them back in

 

Check the wiring and the connectors for corrosion .

 

ive also heard it could be a o2 sensor fuse? Is that in the engine bay or behind the kick panel?

 

If they sat in a box that long and got any kind of dust/buildup/corrosion, they most definitely could have gone bad. Could also be fuses or wiring I suppose. Let us know what you find.

 

dtc p0057 is related to the O2 heater circuit not the cat. check fuse and all related wiring/connectors.

 

Which is based on how quickly the O2 sensor heats up. Threw the same code when I switched to test pipes before I ran foulers. If the cat is bad it will throw the same code.

 

P0057 is electrical. Not a cat problem.

 

Then I'd just start with replacing the sensors and go from there
