Hi, I just wanted to hop on here because I currently have a check engine light on a 2009 Mazdaspeed 3 with 87,000 miles on it reading with the codes P0134,P2246,P0031,P0032. The car currently has a catless down pipe with a high flow cat after the second O2 sensor, not sure what exhaust it is seems to be custom but that is how I bought the car and it is a full turbo back. These codes showed up about a week ago and I just thought it might simply be a bad sensor ordered a NTK one and installed it codes are still here after a reset.
I have been trying to do research to find out what it might be but cant seem to find a conclusion. Some things suggest are maybe a fuse? (None seem to be blown but i am not sure which fuse the heater circuit is). Also maybe bad wiring but when looking from under the car everything seems to be in order. I have a multi meter but I am not exactly sure how to go about testing for continuity and voltage?
Any help or suggestions would be great. Let me know if you need more information, thanks.
