2000 Tundra Check Engine Light

Check with your local Toyota dealer as the O2 sensor on the V-8's are going bad quicker than Toyota can make updated replacements. Had to wait almost two weeks to get the new updated sensors in from the factory.

BTW, my 02 Tundra had 51,000 miles when mine went bad. A friend had his go bad on his 02 after 14,000 miles. Another friend had his go bad on his 03 around 40,000 miles.

Hard to say. Mine came on a couple of months ago about an hour after I got gas. Turns out that the guy at the gas station forgot to put the gas cap back on. It could be as simple as that. Or it could be an O2 sensor, which seems to be the next most likely culprit.

If it is the O2 sensor, you're in luck because Toyota has extended the warranties on them until 90000 miles.

I bet it is the O2 sensors - notoriously bad on the 2000 models I have replaced three of mine so far. Go to AutoZone they will read the code for free and let you know what if anything needs to be done.

Thanks, I'll go to AutoZone today, did you replace them yourself? Was it difficult?

Like I said, Toyota has extended the warranties on the O2 sensors up to

Oxygen sensors deteriorate with use--actually respond more slowly until they finally fail. 130,000 miles is good life, and you were due for new ones. Installing new sensors when the old sensors are responding more slowly should give slightly better mileage and performance.

Hi All

Took my truck to Autofair Toyota of Manchester NH today.

They replaced the front two 02 sensors free of charge... Seemed to be confusion at first about the 7/90,000 bulletin.

But in the end no problems and no charge.

Thanks for the replies
