P1166 primary o2 sensor failed twice within a few months

i got this code back in march i think, I had only had kpro for about a month. I replaced the primary O2 sensor and it fixed the problem.

today I got the code again...what gives? what would cause the sensors to fail so fast? :?

I know some people have had bad luck with them, failing really fast. If your wiring is in good condition and the connector is clean, has good contact then it might just be bad luck :(. My wb is atleast 3yr old.. but the kpro is acting up when uploading :(.

hrm...is there a brand that seems to fail less then oem?

Make sure when you purchase the O2 sensor... it is actually for a 02-04, avoid touching the element surface, IF you are applying anti seize to the threads; dont apply too much.
The two manufacturers of quality sensors is either BOSCH and NGK (NTK).

if it wasnt for the 02-04 it woundn't have worked in the first place, i didn't touch it and I didnt use any anti seize

I would check the wiring harness going to the O2 sensor to ensure it is not rubbed thru and intermittently touching the other wires or possibly a dirty connector where it plugs into the O2 sensor pigtail.
