Oxygen Sensor 2004 Tundra - Warranty or TSB? - Toyota Tundra Forums : Tundra Solutions Forum

Hi,
Does anybody know for sure if O2 sensors are covered under any warranty or Technical Service Bulletin? One of mine failed and the dealer said it was not covered under warranty. I didn't purchase any warrantly above and beyond the standard manufacturer warranty. Just want to confirm there wasn't a TSB that would cover it. It is a 2004 D-Cab with 66k on it.
Thanks,
Ron

As far as I know, the oxygen sensor extended warranty (90,000 mi/7 yr) only covered up to mid-2002. You might give the Toyota Customer Experience Center a call to find out if they issued one for yours. 1-800-331-4331, have your vin ready.

I know this is old, but I recently contacted Toyota about my 02 Tundra for the O2 sensor enhanced warranty./ They told me it was not covered because my truck missed the time cutoff by 6 weeks. Seems this would have been a place where they mght have said "close enough" to keep the customer happy. Nope. It's no big deal to replace it myself.. I'm pretty disappointed they didn't help.

why are O2 sensors not covered under the emissions warranty? I thought that was 90K or 100K or something on all of the emissions parts. I may be completely wrong, of course...
