RE: Trouble code P0133

Bank 1 is always the same as cylinder #1.. HO2S-11 is bank 1 upstream sensor.. The down stream are called monitors.. Check the pins in the connectors for damage and corrosion..What you might want to try before buying a O2 sensor, is switch them from right to left, and you should then get a code PO153 if its a defect sensor, as it'll follow on over to bank 2
