  • My '06 Sentra had thrown a P2A00 code for A/F Sensor 1 Bank 1 so I purchased a new sensor, had it installed and cleared the CEL and all codes. I drove about 100 miles and now I'm getting a P0133 code which is just another way of indicating that the same sensor is bad...but it's brand new and was just replaced. Any suggestions?

  • Do you have any exhaust leaks? If no leaks found (even an small leak will set the code), then the next step is to Clear Mixture Ratio Self-Learning Control Data.
