Toyota Tundra Problem Report
Toyota Tundra Check Engine Light Due to Failed Oxygen Sensor
Check engine light came on...took to AutoZone to scan computer...one bad O2 (oxygen) sensor...ignored due to truck still running fine...checked again, periodically, and now 3 years later - all O2 sensors bad...but still runs! Can this lead to other problems? - Visitor
Engine light came on, had it checked at auto zone, reading of circuit low 02 sensor bank 1 sensor1. Truck is jerking when excelerating, is this caused by the sensor problem? - Visitor
Check engine light came on and had it diagnosed for the O2 sensor. Coincidently, my previous truck was a T-100 with same drive train. When that O2 sensor went out at 121000 miles, the service advisor let it slip that the computer is set to trigger an O2 sensor replacement at or near 120000 miles. How coincidental is it that nearly every complaint listed here (self included) has a problem at the 120000~ mile range..... Currently have 226k miles on my tundra and am patiently awaiting the check engine light to come on again.... maybe the consimer guru recently appointed should get Toyota to refund this 'rigged' repair... or remove the computer trigger or, reduice the repair cost if this is truely a time change component! - mmikel52686
Check engine lite came on.. Replaced gas cap.. Lite turned off by tech 150 miles later ..no lites on but could not do nys inspection module not reading. Truck drove by tech,,o 2 sensor replaced. Still not clearing module. Truck running fine. What is Toyota tundra reset routine? I found a generic method on dmv web site. Any thing special for my 2001 truck 63000 miles V8? Not fixed... - Visitor
had both top oxygen sensors go out replaced them myself for about $60. ea. autoparts123.com & saved a bundle over the dealer service dept. You will need a special socket for the sensor (my neighbor had one) Not very difficult if I can do it. You of course need to know which ones are out ! Most parts stores will scope it for you. Good luck - Visitor
Failed o2 senser. Engine light - Visitor

Check engine light came on...o2 sensor replaced. - mizbonnie
Had one sensor on left front bank go out but I was smart I bought all four. Sure enough after I replaced it the rear sensor on second bank went out not that long after so being that I had all of them I replaced every one and now been ok. Next time one goes out I'll end up buying all four again save yourself the trouble - itsjustjesse
ultimately had to replace all 4 sensors - Visitor
Engine light came on...code was for bank 1 ,#2 sensor....told at parts store that's the one before the cat.converter...180.00 later.....replaced that same sensor one year ago ???? Bosche makes them,NGK,etc....is there a preferred?or are they all made in China....? also heard fuel injector cleaner effects their longjevity. - Visitor
My limited slip stopped working and these Cluster lights limited slip, vsc off, vsc trac, and check engine lights are on. Took it to toyota of Renton to have it scanned. They said its one of my o2 sensors. To find out what one they want $130 just to diagnose it plus the cost of repair and part. I will do the work myself. - Visitor
The check engine light came on. I got the truck checked at the dealership and they could not diagnose the issue properly. I was told that the O2 sensors were bad so I got them replaced. The light came back on again. I contacted a friend who works at another dealership, he said the machanics see this alot and said it can also be from a cracked exhaust manifold. This is apparently a problem that is frequent in the Tundra. Waiting on a recall. - robert.s.sweeny

Check engine light. Bad O2 sensor. 15K more and a second sensor near the catalytic converter needed replacement. - Visitor
Replaced one oxygen sensor now the second one has gone to. - 211wizard
The O2 sensors have been a problem on this vehicle from the start. In order to pass emissions, I had to purchase new sensors and now I have another problem with the same sensor. I think it is rediculous to pay so much for a sensor that continues to go bad and cost much money to repair. - NeilATL
