Model Years Affected: 2000, 2001, 2002, 2003, 2004, 2006

Average Mileage: 105,199 mi (13,688 mi - 226,025 mi)


One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.

  • Check engine light came on...took to AutoZone to scan 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?

    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?

    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!

    150 miles later 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...

    had both top oxygen sensors go out replaced them myself for about $60. ea. & 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

    dealership stated that engine light was on because two oxygen sensors had failed. I have not repaired yet but the estimate for repair was $650.

    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
