#3375 of 3687 2001 Engine Noise driving me Crazy
Sep 06, 2005 (8:20 pm)
Hello all, I own a 2001 Sienna LE. I bought it new and after about 12k miles began to hear a knocking noise. The noise occurs all the time after the car has warmed up. It is loudest when the van climbs hills. I've taken it to the dealer and after being told they can't hear it.(I took the mechanic around myself then he could hear it.) I was told that they scoped the valves. Can't find anything wrong with the car and the noise is normal. I change the oil every 3 to 4k miles currently have 40k and the noise continues. I'm considering getting rid of this van and going away from Toyota. Was wondering how anyone else has fared with this problem?

The computer controls the engine timing as far as advancing the spark or retard - whatever the case. From your description it sounds like it's not working correctly.
I would have them c/o the computer.

Sep 16, 2005 (5:14 am)
I got a CEL light in my 2000 Sienna and the code is P1130 (air/fuel sensor, bank 1). The van has about 53K miles on it. The light comes on sometimes and then goes away sometimes. Should I bother with changing the sensor. I believe this sensor is hard to get to because it is on the rear side. Has anyone been able to get Toyota to pay for this, either under TSB EG012-02 or some other program?
#3378 of 3687 Slow Fuel Refill
Sep 20, 2005 (10:57 am)
My 2002 Sienna XLE has never taken refueling very fast and the probem has gotten progressively worse. It takes a couple of minutes per gallon to refill and you must stand there nozzle in hand to do it. Even the lowest setting on the automatic flow is way too fast. Anyone else with this problem?

#3380 of 3687 Question about transmission/differential fluid change
Sep 21, 2005 (10:27 am)
First time changing my own transmission and differential fluid in my 2000 Sienna.
I see there is a hex drain plug on the transmission pan which allows about 4 quarts to drain out. That looks easy.
In addition, there is a drain on the differential which also requires a hex wrench located sorta above the pan on the transaxle. That looks easy as well.
I am not sure if the differential fill is through the transmission dipstick tube, or if there is another place to fill the differential. That's my question.
I've also been told that the system holds much more than the 4.5 quarts I expect to drain, and that flushing and filling the system with synthetic fluid is the only way to really effectivly change the fluid. Local place wants $199 to do that. Is it necessary? Sound like bunk.

Good to see you doing your own work you can save a ton of money. I have a 2001 Sienna that I have done twice. The diff gets filled on mine from the trans all you do is add through the tube like you said. As a added check once the job is done slowly back out the diff bolt until you see fresh fluid drip out thats what the 2001 did the 2000 should be the same.
Mine took about 3 quarts. I always used a name brand the standard kind. I myself would not change the fluid type because you will never get it all out then you have a mix.
#3382 of 3687 2003 Sienna - any known problems?
Sep 27, 2005 (6:56 pm)
I am planning to buy a 2003 LE or XLE.
Are there any known problems with the 2003 model? Given that this was the last year (Sienna got redesigned in 2004), I figured it should have the least amoung of problems.

Thank you for the information. It has taken me a month to get back on-line. Sounds like orange is my color for now.
