I've had the same problem with my oxygen sensor (engine check light) on my 2000 v6 tundra that many many many people seem to be having. I've had the local foreign car repair shop(friend) read the code PO135 and turn the light off twice . It would come back on within 1000 miles. Once or twice it would go off for a time and then come back on. Did the battery disconnect trick once which does turn the engine check light off for a while.
The sevice manager at my local Toyota dealer ,after he assured me there was no TSB out on the o2 sensor, told me basically just to live with it because it was JUST a pollution control issue and would not effect the performance . I have educated myself on the other function of the oxygen sensor.... other than just to fail.
So after ordering my new Denso sensor from sparkplugs.com I went out last night to look again at the suspect failed sensor on my truck...only this time I checked the connections at the sensor and on top of the transmission where there is a junction.
toyota o2 sensors are damn expensive. I need one for my 81 pickup, $125.
Guys, 02 sensors are one of the most important components on your truck. A bad 02 sensor wont let the engine go into closed loop, which means best fuel economy. Basically never over look the 02 sensor.
Took my truck in for "Check Engine Light" today. Had a bad O2 sensor. They told me it would cost $240.00. I told em to shove it!!!
HA 240 DOLLARS WHAT A RIP OFF.You shouldnt have trd install they will rip you off.It takes 15 minutes to change o2 sensors.Go to a local auto parts store and rent a o2 sensor changer thingy.

With the numerous premature O2 Sensor failures and given Toyota's past reputation for unbeatable quality Toyota should replace these sensors on all the trucks for no fee, just like they did with the faulty headgaskets on the on the V6 Hi-Lux and the Tacomas. In fact, if it was found that a faulty OEM head gasket on those trucks caused engine damage, Toyota would replace the engine at no charge.

The back ones take 15min. The front ones take about 2 hrs, if you take the heat shield off. :cry:

You might try being a bit more cordial in your responses...

maybe we should all write to Bosch or someone and ask them to look at this problem. Maybe they, or someone who is an expert on O2 sensors, can make a better sensor.
I'm getting this same problem on my 60K 2001 Highlander, front bank O2 sensor MIL. In addition to the MIL it also lights up the VSC, which is odd. The light will go off on it's own, but then it pops back on again.

I had the dealer replace the bank 2 sensor on my 2000 Tundra at 48K. Now the bank 1 sensor is gone at 61K. Rather than pay the dealer another $200 I'll pay the $87 bucks Autozone quoted for the part and put it in myself. Question -- is bank 1 the right or left side, and is there only one O2 sensor on each side? Thanks
At 67k miles, I had the MIL light come on about 2 weeks ago. Bought a reader from ScanTool.net, read that it was sensor1,bank1 O2 sensor. Bought 2 from sparkplugs.com, only $47.85 each, what a deal! Drove the truck about 500 miles before replacing them and noticed no bad side effects. This past weekend I replaced the front 2 sensors in about 30minutes. Getting the heat shields off was tricky, but made replacing the sensors easier. I will leave the shields off in case I want to try some headers later(actually, I thought I might have the manifold leak everyone talks about, but the heat shields were clean. Guess it's just the cold engine knock after all.) /Mike

If the O2 sensor lasts for 30-40k miles or more than you don’t have a problem! They have a service life just like a spark plug do and wear out. I know someone is going to post “but my 1990 Toyota Camry went 200k miles and never had the MIL light come on”. To that I say that Camry didn’t have OBD2 and it may or may not have had heated o2 sensors.

Buy your sensors from www.sparkplugs.com. These are OEM sensors (Denso). You have two sensors per side. Bank 1 sensors are on the drivers side. The # 1 sensor is before the Cat. converter. the # 2 is just behind the cat. converter. You will need a 22mm or 7/8 crows foot or offset O2 sensor socket and a 12-15" extension. I had to jack my truck up some to get under it. If you take the heat shield off you will get to it much better. The heat shield is time consuming. It has 4 bolts that you can't see, so it takes awhile to get it off. :cry:
