Good morning,
First of all, the sensor needs to be a quality sensor. EBay sensors are cheap sensors and do not meet OEM specs.
The 420 is a catalytic converter issue. The cat converter needs to be replaced.
The 133 is for the sensor. I would start by replacing it with a quality sensor.
1148 is also indicating sensor issues.
130 is also a sensor code.
I would suggest replacing that sensor. The catalytic converter also needs to be replaced as well.
