O2 sensors

[Kel83]

I have a 2000 vt commodore and just replaced the O2 sensors in it and now the check engine light comes on when I'm on bout 70-80kms... Does it need to be recalibrated to the computer or is it a different problem???

see what the code says, the sensors don't need to be calibrated should just work

Check what the error codes are.
