Hi, I had turner test pipes and stage II tune done about 3 months ago. Last week, I reflashed the ecu only eliminating the launch control option which I found useless. Yesterday, I got an increase emission fault code(274a lambda sensor pump current assimilation error vkat bank1) I believe this is referring to a bad pre-cat o2 sensor. I cleared the code but it came back within an hour.

I do recall recently reversing into a parking spot and bump the bottom of my exhaust on the parking space cement block. Any chance, that could have dislodged the sensor and/or piping which caused the CEL?

These o2 sensors + labor is NOT cheap so I'd appreciate your insight on what other quick fixes may exist. It's hard to imagine that the test pipes and tune didn't play a role. this is slowly turning into quite an inconvenience to say the least.
