Catalytic Confusion??
 
Hey guys,
I have an '04 with a few mods,(K&N CAI, Dal exhaust, and long headers). Recently i bought the Superchips Cortex Tuner and uploaded the 87 octane tune, soon after i got the P0420 code for the Catalytic effiecency Bank 1. i only have 68,000 miles on the truck so i wold be suprised if the CATS were bad. Also ive seen pics of the cat converter and it looks nothing like what i have, i have 2 seperate cats(i think).

Would the CATS go bad that fast and have to be replaced? If its the sensors, how do u know which one to replace?:4-dontknow:


Thanks:smileup:

x2...it sounds like an O2 sensor. We need the advise of an experienced tuner that knows which bank is which location.

Get a set of new O2 sensors and try them before you go through a set of new cats.

with the O2 sensors, would they be before the CAT or after? Or r u guys suggesting replaceing all 4 sensors?

It is the sensor after the cat on the driver's side. I had this same code before when I installed LT's and high flow cats.
