Code P0431?
Hi Everyone,
I'm sure this issue came up in the past. I have not be able to find it. My 05 CTT CEL came up and the code is P0431 bank 2. I did some research and found out that the code is related to these symptoms.
The catalytic converter is no longer functioning properly
An oxygen sensor is not reading (functioning) properly
There is an exhaust leak
Have any of you had this code? What parts triggered this? I'm thinking its the O2 sensor. I want to double check with you guys first before ordering the parts. Is there a CTT DIY page how remove the O2? Thank you.
