Hi, I have a 99' camaro v6 throwing a P0147 code (O2 sensor bank 1, sensor 3). Before replacing the O2 sensor, I was told to check the fuse first. Looking in the GM car manual, I didn't see O2 sensor in any of the fuse descriptions. Does any1 know which fuse this would be? Thanks.

Also, any1 know a good place to buy this O2 sensor, if needed? I've seen them in the $60-$70 range on various websites.

 

The heater portion of the O2 sensor is fused, but only has power with the key in the ON position. The fuse is usually labeled "FANS/ACTR" or similar. No need to remove fuse as long as thee key is turned OFF.
