at 60,000 miles I replaced the computer (parts $500) for the power door. Dealership didn't charge for service as I complained that the door from time time got stuck since new.
Any way currently 74,000 miles and 11 months since above repair. And acting like the computer is out again.
Should I expect the Toyota to pick up any of this?
I try to get a good filter but have had the normal Toyota filter installed when I don't have the good filter. The oil gets changed at 6,000 + - 500. Most miles are short trip city driving in Northern CA.
What type of maintenance did you do on the transmission up to this point? How many miles are on it?
Also, for other's benefit, if you keep your address updated with Toyota (call the 800 customer service number to update), they will send you mailers when a new "service campaign" like the extended transmission and engine warranties come out.
I have a '99 with 98,000 mile on it. I have been "over maintaining" the transmission by dropping the pan and cleaning the filter every 30,000 miles as well as draining the fluid (twice) every 10,000 miles. It costs me $9 every 10,000 miles, but I hope it pays off in the long run.
A/F Sensor Circuit Range/Performance (Bank 1 Sensor 1)
A/F Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
Has anyone encountered this or have recommendations on what to change?
A post on http://experts.about.com/q/832/index.htm states that this requires a special tool. See "1999 toyota sienna check engine light" dated 11/22/04 on this link.
There is just a connector that the sensor connects into. It kind of looks like a spark plug with a wire pigtail off of the top. Mine just took a standard open end wrench to remove. The back/firewall side is hard to get to if you have large hands, but it is "doable."
At what mileage should the Iridium spark plugs be replaced ?
I bought this used 2000 Sienna a few days ago. Today the transmission failed(@47K) on a highway leaving the family stranded. I got it towed to the nearest Toyota dealer, but couldn't talk to the service people as it is week-end.
The usual Toyota power-train warranty on this vehicle may have expired. as the original date placed in service is 5 years 2 months ago.
I read somewhere that Toyota has extended the warranty on Transmission for 98,99,2000 model Siennas for up to 8 Yrs/100K miles. Is this true? Is it applicable to all vehicles of those model years? Are there any regional variations on this policy. I live Southeast and I learnt Southeast Toyota is somewhat different from everywhere else.
Thanks for any info & advice.

Engine check light on.
DTC code: po155 O2 sensor heater circuit malfunction (Bank 2 sensor 1)
Does't anyone know where is the location of this sensor?
I plan to work on it during spring break (March). Does it hurt the engine or other part of my car if I don't fix the problem until then?
Auto part store told me that the cost for the sensor would be around $170. Anywhere I could buy cheaper one?
Thanks in advance for any advise.
I've made an appointment at my dealer for Friday--I'll update on the outcome of that! Glad to know I'm not just hearing things!
[Edit] I forgot to mention that my sister had two bad O2 sensors on her New Beetle that she ignored for three months. As far as I know, the only downside in waiting to fix them was her mileage tanked.

Front is easy to reach, I'm told the back is very difficult to reach and needs a special tool. It looks to me that all it needs is a small arm and a good grip, although I haven't been able to tell exactly where the wires from the part go to.
Since this is such a common problem part, has Toyota stepped up to assume some responsibilty for anyone?
I hesitate both to have a non-dealer fix the problem, and to do it myself because of it's location. And I'm also afraid of being taken to the cleaners if Toyota fixes it....
FREEBIRD: Where does the rear sensor wire connect to the car's harness? Can you detail what it's like to change part?
I changed my back sensor from under the car. I just had to work my hands between the firewall and suspension to get to it. I would say that if you have large hands, it would be difficult to do.
Let us know how you make out.
Thanks... it's good to benefit by one's experience and I guess that's what these boards are all about.
we have a 98 sienna that has sludging and transmission problems, and i'd like to let them know of my dissatisfaction with their horrible product. (the sludging was somewhat bearable to go through since they covered the problem, but the transmission didn't fail until 6 months after the special warranty expired, so we had to take care of that ourselves).
thanks!
1) at how many miles did the engine show problems? How about the transmission?
2) what were your oil change and transmission fluid change intervals? I change oil at 3750 miles, and trans at 30,000. My van only gets driven about 10,000 miles/year though.
If you look at the O2 sensor connector on the front as described earlier, then you will see the exact connector that you will be dealing with on the rear.
If you do a search of Edmunds for "sludge" you will find an old archived discussion that was started by Toyota to address the sludge situation. I think I remember seeing ways to contact people at Toyota. Again, this was for the engine, not the transmission. It won't hurt to file complaints with the NHTSA at http://www.nhtsa.gov and the Center for Autosafety at http://www.autosafety.org.
Good luck. If I come across any information that may help you, I will post it.
transmission failed around 155,000 miles.
changed oil about every 3000 miles. never changed transmission fluid - (bought car with 70,000 miles) supposed we learned an expensive lesson from that
the sludging warranties for 8 years regardless of miles. the mechanic at toyota told us it will definately sludge again...it's just a matter of time. it's a 1998, so hopefull it does it before 2006. a local mechanic said he's had customes add a touch of transmission fluid to the oil and never have sludging problems again...anyone ever heard of that?
the transmission warranty was a time issue, (regardless of milage), which ended in may of 2004. (of course our transmission was fine until nov of 2004...isn't that the way the cookie crumbles)
thanks for your responses!

They're $300 each installed after they do their "required" diagnostics! My local Toyota dealer in Wellesley, MA wouldn't do a thing about it, other than to charge me.
