#1 of 31 O2 Sensor Failure on Tundra
Dec 31, 2002 (2:41 pm)
This morning my wife took my Tundra out to the post office and got about 1-2 miles when the Check Egine light came on. She turned around and came back home and I took my 2001 Tundra 2WD SR5 AccessCab to the nearest Toyota dealership's service department.
An hour and a half later I was informed I was ready to go. When asked what happened, they said the Oxygen sensor had failed and they warrantied the repair. I asked what caused it to fail and they had no clue, but added it wasn't uncommon on the Tundra V8 line.
Since TundraSolutions does not allow non-paying subscribers and guest to do searches or posting in the Technical section of that site (I understand perfectly, as it would be a valuable resource), I am looking elsewhere.
Has any other Tundra owner had a problem with an O2 sensor, or any other sensor going out? I have about 27K miles on the truck, of which 90% are non-rush-hour interstate driving. I change the oil regularly with fully synthetic oil and performance filter and never had any problems.
Last Saturday, I got lazy and instead of changing the oil myself, I took the 7-quarts of Mobile one and appropriate Mobile 1 filter to this very same dealership to have them change it (and they did for $9.95!). I also had them rotate the tired, but they screwed that up by rotating only two of the four tires.
Just curious. No problems until after I have someone do something. Coincidence?

I know two people who own a Tundra and they have both had the same problem. One fellow twice. I can't verify, however, if this is a "common" problem.
There is a Tundra board here at Edmunds. I'd post the same question in there and see if you solicit any responses.
Best of luck,

just wondering but the tundras take 7 qts of oil for a change?

No, seven quarts are not required. A little over six quarts. In order to 'be prepared' I brought more than what was needed.
BTW, I thought I has posted to the Tundra board. Did I not do this? The 'You are here' says Town Hall>Toyota>Tundra. I'll post the same in the Owner's Clubs, too!
#6 of 31 3 times a charm

I've just had my 3rd O2 sensor failure, this time out of warranty, so I'm replacing both remaining ones myself since I'm sure the 4th will go soon. I've read that it's about a $200 repair at the dealer(each), or $150 for the parts-only, but I ordered the parts online for $116 each and will be doing it myself. Looks real easy, they're attached to the exhaust at 4 points, two in front of the catalytic converters, two after them. The only problem you will have is testing to see which ones are bad.
So yes, this is a "common" problem with the Denso sensors Toyota uses. But if this is all the major trouble I've had with my '00 Tundra in 40,000 miles of heavy duty use (towing/hauling daily) I can't really complain. Other "problem areas" would be the drum brakes, that got out of round at only 20K miles, but they fixed that for free. Oh yeah, my belt is also a little squeaky when cold. Replacing that with a Goodyear Gatorback belt for $27.
#7 of 31 Remember emissions warranties are longer

If your o2 sensor is giving you problems, don't just buy a new one, as it may be covered under emissions for 72,000 miles. Not sure about this but worth looking in to.
Jan 24, 2003 (11:00 pm)
they won't cover it, even though they probably should.
#9 of 31 o2 sensor problems
Jan 27, 2003 (4:33 pm)
I too have had the sensor problem, mine at 70,000 miles on a 2001. After my check engine light came on I took it in and they want to replace all 4 sensors at a cost of about $800.00 total.
My question, any harm done in not having these replaced for a while?
#10 of 31 Now the other one went out!

Yessir, now the O2 sensor on the passenger's side on the exhaust manifold has failed. Also, the sensor froze in the manifold and they are replacing the exhaust manifold, too. I'm in an insulting Chevy rental (against my will) as the repair will take +5 hours and it was 3PM when they made the determination.
So, being that it has only been two months since my first O2 sensor I wonder if this isn't a chronic problem we are seeing. Two sensors gone bad and only at 28400 miles in 18 months of ownership for this vehicle I bought brand new.
BTW, the sensor and manifold repair bill (under warranty) will be about $600.
