Mechanic says 02 sensor needs to replaced.
How many 02 sensors are there in Toyota Sienna 2009
And what are the possibly that could be the problems?
It has 97k miles on it.
The codes that I found out was:

Any advice ?

It is manual. Just happened out of no where. It only has 135,000 miles. I noticed other vans reported this problem with this year. I just had my car at the Whittier, CA Dealership. So far no answer, help!

hesitates/jerks at fast acceleration. Would like a general cost for repairs please

I removed the Bank 1 & 2 sensor and it was black. Sensor 3 is clean. Twice over the last 6 months I have a foul order. I'm guessing the Cat may be bad, but how can I be sure?

The button that opens the fuel door when the release is pulled is so tense, you can hardly push it in. It broke the hinge on my fuel door and the door won't close properly. How do you adjust it so it's not as tense?

As an interim measure, dealers will remove the spare tire and store it in the cargo area of the vehicle. Dealers will replace the spare tire carrier assembly when parts become available. It seams that Toyota is not following through on the parts and owners of the 2004 to 2011 Sienna's are left with a tire in their 3rd row seating area. What is the recourse? They call it an "interim" solution (been going on for 4 years)

I discover that when ever I start my toyota sienna 2002 model and drive it will stop as I match the brake

Can I pop out inside liner from inside?

Dealer claims there is a leak (I've never noticed any) and wants $1275 to do the work.

2005 Sienna XLE sliding driver's door opens with both overhead electric switch and the column electric switch but they won't close it so I have to close the door manually.

I changed bulbs in tail lights my dash doesn't say anything is wrong.the fuses look good all other lights work fine what to do to get tail lights working again

I am able to operate the door manually with no obstruction or resistance.

any suggestions on diagnosis?

oil pressure light comes on after driving for a while and there is a noise in the motor when light comes on.

Can't get to them through the access door panel. No screws visible on the lens. Anybody have a clue?

While in Drive heading around corner, total loss of power like transmission went but after parking for 2 hours, the car drove again and shifted well. It has been acting sluggish after stopping. When the car would not go, engine was still on and revving but no power. Tried 2,3 and 4 but these did not work either.

The repair was authorized by TOYOTA in Dec 2014 or Jan2015

The was washed and on the second day the door could not be opened by any button except manually.

Sunroof will always open but when we go to close it, it will not immediately close with the button pushed in. We have to hold the button for minutes to get it to close. Sometimes we have to turn on and off the vehicle several times to get it to close. I feel that it has something to do with some type of module.

we have had 3 times now when the rear brakes froze like the emergency brake is stuck on (its not). if you attempt to drive the wheels wont unlock until you get enough force to break them loose. why does this happen? getting the vehicle washed in below 32F temps? my other vehicles dont have this problem.
