Light wouldn't go away after replacing 02sensor

Question

I just replace an 02 sensor low bank 1. P0031 in a Toyota corola 2006. I reset the light and run the car. But the check engine light keeps coming back on in the dashboard. And now the car is shaking and it turns off by itself, when it didn't do it before replacing the 02 sensor. Any suggestions??

Answer 1

When you say you reset the CK ENG LT, did you disconnect the battery,? If you did you do a idle relearn, place in Park bring the RPM to 1200 to 1300..Hold it there, for at least 30 seconds turn the a/c on hold do this for a whole minute,
