05 TL, HFPC throw code
I got rv6 hfpc, and I installed only the front pipe just because of time restrictions. I installed everything back together no issues but got a code (P2631). Is it because I only installed one of the new pipes? I was thinking the car is confused with one oem cat and one hfpc.. I’ll replace the back one soon, but can anyone shed some light on it?
