O2 Sensor Factory Warranty?

What is the factory warranty for an O2 sensor? Thanks,

 

Your owners manual will tell you. It will tell you what is part of the emissions warranty, what’s included in powertrain and what is part of the bumper to bumper.

 

5years 60k miles normally. Unless it's not part of the power train warranty

 

On my 2002 TRD off-road 4 x 4 the O2 sensor went bad at about 85,000 miles. Replaced it. 7 miles later another O2 sensor was kicking an OBDII code. Replaced it. 21 miles later a third one set it off. At that point I said, “e’f this” and drove it like that until I traded it in with 213,000 miles on it.

 

Emissions parts are typically 10 years/ 100k but you should check

 

It lists emissions items as 24mo/24K miles or 96mo/80K miles but doesn't list the O2 sensors specifically. Called 3 dealerships & none of them could tell me.

 

That’s shady that a service advisor won’t/can’t tell you if a fault is covered before you give them your truck. A call or email to corporate may be needed. But if I was a betting man I’d say if it’s not explicitly listed, it’s not covered beyond the 3/36

 

Crawled under my truck to mess w/the Bank 1, #2 O2 sensor due to a check engine light (code 0037) & the damn thing was unplugged! I have no idea how that happened. It came on about 225 miles into a road trip. I'm assuming the code will clear itself after some key cycles & miles?

 

Different types of codes have different reset requirements, some of the emissions ones require specific driving conditions. The code sites that tell you what they are should tell you reset conditions
