My CEL is on and I had AutoZone pull the code: P0141. Report shows the probable cause is a faulty O2 sensor (Bank 1 Sensor 2), poor connection at O2 sensor, or the circuit. I replaced both upstream sensors and checked the connections and am still getting the CEL. I can't seem to locate the fuse that is assigned to the O2 sensor. I checked the owners manual and a diagram I found on a thread here but no luck. Any ideas on where it is located? Since I've only driven the truck about 100 miles since I replaced the O2 sensors could it take a while for the computer to reset? Thanks.

If you can't get someone with a scanner to clear the code, the other fix would be to disconnect the negative battery cable for a few minutes.

I doubt there is a fuse for the O2 sensors. They are part of the PCM circuit and that would be fused.
 






Isn't bank 1/sensor 2 downstream (after cat conv)?
