Alan_S hasnt posted in 6 years so I'll answer. There is a TSB for your problem. Here is how you get it. You will neeed to buy a new handle assembly. Go to dogpile.com. Type in "AARC auto repair" in the search box. Then click on Bedford Public library link. Then click on the ARRC link/picture. On the next page, click on 1998 then click on toyota then sienna then service bulitins and recalls. Then down to Glass Doors Hood Deckid, etc..... There are a couple of TSB's regarding your problem. Look through them and read them.

There is a new kind of alternator that has better output while sitting at a light or idling with accesories on. That is your prob.
#3598 of 3687 sienna acceleration noise
Aug 06, 2006 (6:12 pm)
2003 Sienna were just on a road trip noticed a noise that sounded sort of like static everytimeI would accelerate it would go away when crusing but come back during acceleration. any guesses as to what this would be??

If the radio is on, it very well could be static from various engine compnents. If not, then it can't be static. It could be a rattle, which sounds like static somewhat. If it is, then check the following:: Secure objects in the cabin, secure engine and transmission mounts, secure exhaust hangers and clamps. Check those and get back with me.

The radio is not on. I said static because i was trying to describe the noise. It only makes the noise when accelerating.
Once i ease on gas the noise stops

Just look at the things I told you. Also, I thought of a couple more ideas. Check drive belts, and pullys too. Since I can't see or hear your van, its hard to help you. I have never heard of such a thing.

could be hard to diagnose issue, but some additional sleuthing may strike paydirt.
some ideas from a fellow motorist:
sit in the passenger seat and have someone else drive to re-create the noise. often helps you determine the thing causing the noise (localizing or better pinpointing the source). you will not be distracted with the act of driving and you can move about in your seat to get a better sense. you can roll the window down and stick your head out.
you might even let someone drive the car by you when your standing in the parking lot.
trust me - it can all help.
i'd try to determine if you can re-create the sound when reving the engine in park. if so it's probably not transmission related (which is good - 'cause a transmission issue could be expensive).
try this: shut the car off, open the hood, make sure car in park and parking brake on, restart the car and have someone else hit the gas while you listen to things in the engine compartment. maybe you can localize it. have them cycle getting on the gas hard and letting up. listen listen listen. move around the car while this is done. let your ears help localize the sound. we have 2 ears and the ability to move our head and body for this reason.
you have correlated it to acceleration / cruise. that is a good good start but still a bit too general.
it could be belts on your pulleys, it could be a loose something or other in the engine compartment (a loose windshield fluid resevoir for example), a piece of metal or plastic somewhere.
with the car off and cool, use your hands to gently determine if anything is loose (has excessive play) in the engine compartment. perhaps a bolt holding something on or tight to the engine side walls or another engine component is loose.
penizzle has suggested an exhaust issue. very probable.
many cars have heat shields on the exhaust manifold (where the gasses from each cylinder exit the engine and are collected and sent to the catalytic convertor and muffler), and/or around the catalytic convertor, and/or the muffler.
a loose heat shield could be the issue. with the engine cold, car in park, emergency brake on, you could try to sneak under the vehicle, even using a long stick or piece of wood and see if there is any loose shield from the engine back to the exit of the muffler at the back of the car.
another possibility is a missing or disconnected "exhaust hanger". these are made of hardened rubber (like a black thick rubber band) and will connect to a hanger on the body of the vehicle, and another hanger on some exhaust pipe or muffler etc (there are usually a few of these things...3 or 4). it will hold the exhaust system in place, but at the same time, help hold it away from any other metal on the bottom of the car. it also allows engine vibration and movement to occur without fracturing the exhaust piping...it can move with the engine, and not be transmitted to the engine compartment.
when the engine revs, a few things, it's position changes somewhat and it's vibration level can change, and these can can be coupled to the body of the vehicle somewhere. we already discussed the exhaust and hangers.
a bad engine mount (the things holding the engine in place in the engine compartment - there are probably three) if damaged, can allow that engine vibration to be poorly damped, coupling vibration to the engine compartment, and the movement of the engine to be greater than it otherwise would be as you get on and off the gas.
other possibilities include loose plastic on the under-body of the car up near the front (for example protecting the oil pan). other pieces of plastic probably exist in the driver and passenger wheel well.
i hope i'm not confusing you. if so - i apologize.
you're on the path of discovering what's going on. it's gonna take some work.

#3604 of 3687 Seinna 2006 Power Outlet
Aug 08, 2006 (2:55 pm)
We plug our portable DVD player into one of the outlets in the front dash. When we turn the car off and then back on the DVD player powers down and then back up. This starts the movie from the beginning. Is their anyway to rewire the outlet to keep power to the outlet continuously?

I have this same problem. We bought a used 2001 Toyota Sienna last month, two days later, the check engine light came on.....then it went off for a week, and came back on and has been on since then. I havent called the dealership as we bought it AS IS. Do you know how to get the code from the computer so i can see wh at the problem is?
