P2626 Code
Hi all,
Check Engine light just came on while driving today( I haven’t been driving this car too much for the last six months) and P2626 “O2 Sensor Pumping Current Trim Circuit / Open Bank 1 Sensor 1”was the code that was pulled from the OBD reader. Any suggestions on how to address this? I do have new spark plugs, O2 sensors, and oil kit on the way from FCP Euro since car is due for oil change and plugs. Car has 96k miles running MBH Long Tube Headers with Renntech tune and no cats, as well as Fabspeed spacer/cats for the last three years with no issues till now.
Thanks in advance.

haven't seen this code...i would install the parts you've ordered and report back if they've solved the issue.

Update: After doing the oil change, installing new spark plugs and new air filters, as well as replacing the passenger side upstream O2 sensor, the car is running smooth again and the light has not come on anymore. On a side note, I actually erroneously ordered the driver side upstream O2 sensor( which is shorter than the one for the passenger side) and installed it on the passenger side anyways. I guess they are interchangeable, but time will tell for sure.
