#1 of 4 1999 Chevy Express P0141, P0420 Codes

Hi, Anyone have any repair ideas for the following codes? I believe I need to replace OS Sensor Bank 1 Sensor 2 but really have no clue which one that is and how to locate it.

That code is for the oxy sensor on the driver side behind the cat. I found mine rubbed through and bare wires were touching the chassis. Replaced it with another sensor and no more code. If you do it yourself get the tap to clean the threads out, TRUST ME on this!!

thanks a bunch. I did surmize it was passenger side behind the cat, so replaced it., cleared the codes and the light came back on and has been on ever since. I thought the light was malfunctioning or something. Guess I replaced the wrong one. By chance do you know what could be the problem if my airbag light comes on intermittently on this vehical?

Sorry I can't help you with the air bag code. Glad the other help worked out.
