Have a soul with around 222,000 miles and recently have a check engine light and P0133 code. There were a few more errors resolved by replacing the gas cap.
I've replaced the upstream O2 sensor with a Bosch without improvement. I can see the voltage switching from .1 to .9 volts using Torque. Trying to decide if I need to install a Kia sensor, possibly clean the MAF sensor. All wiring looks good.
Any suggestions greatly appreciated.
