It's probably a crack in the rubber intake hose between the air metering unit and the throttle body. I've had it happen 3 or 4 times on my vans. New hoses are expensive so I usually just sealed them up with gasket maker. If that doesn't answer your ?, email me. Eric

Which van is best Toyota Sienna or dodge caravan?

The sienna is a more stylish car that from most people would say the sienna overall is a better van and i would go with that, but the grand caravan is a less-expensive van that is still ( but not as good as the sienna as i said ) a very good van, i would say go with the sienna if you're buying a van but if it is not in the budget go with a caravan as a second choice.


Where is the dimmer switch on a 2005 Toyota Sienna?

The trip odometer switch on the odometer itself is the dimmer on Toyota Sienna. If you turn this switch all the way to the left your panel would become dark. Simply turn the switch to the right and all panel lights would come on. I had a similar problem and the manual bailed me out.

How do you replace Toyota Sienna dashboard dimmer switch?

Not sure if this helps or not but on a 2005 Toyota Sienna LE, the dash-light dimmer switch is actually the trip odometer reset switch. Turning the trip odometer reset switch left or right controls the dash-light levels. Had it not been for the factory manual, and Google, I would have never known this.

How do you remove the dash on a 2001 Toyota Sienna?

Get a Toyota shop manual before you attack the dash. There are a number of screws and clips that are not obvious, and there is a good chance you will get frustrated and break something if you just go at it. On the Sienna, I had to remove a good portion of the dash just to change light bulbs on the instrument cluster. I have a shop manual, and the job went smoothly. But I would have not figured it out without the instructions.


Toyota Sienna fuel filter?

To my knowledge after 2001/2, Toyota no longer uses an external fuel filter on their Sienna models, all the fuel filters are incorporated with the fuel pump inside the tank. Should your model still have an external fuel filter it would be underneath the air filter assembly. You could verify by following the the fuel line/hose. copied from FixYa

How do you reset your 2006 Toyota Sienna air bag light?

Our 2006 Toyota Sienna air bag light was blinking, so we took it to the dealer and discovered that when this light is "ON", the air bag system is deactivated and the air bags will not deploy during a collision. We also discovered that other Sienna vans had the same problem as ours, and that Toyota's repair proceedure requires install of a new air bag. Our van has been at the dealership now for over a month waiting on the new air bag, as Toyota has not been able to find us one !!! I suspect that there may be a "recall" of these 2006 Sienna vans due to the liability of someone getting involved in a "wrongful-death" collison when the van's air bags do not deploy. If your van is still under warranty, I would suggest contacting Toyota for a new air bag. Doug Hainer, Sienna Owner Our 2006 Toyota Sienna air bag light has been replaced now three times. The dealer keeps telling us that it is a problem in the wiring. Every time they replace the connectors and air bag the system works flawlessly for about 3 months. The most recent fix occurred 2 weeks ago and this time they replaced the entire wiring harness!!! I also suspect that Toyota will be recalling the 2006 Sienna's because of this problem. Doug Tyree, So. Cal Sienna Owner

Why does my 2005 Toyota sienna xle left sliding door only open a few inches then close It will not fully open?

Just a thought. I have a Toyota Sienna also. The gas compartment is on the left side. If the gas compartment is even popped then there is a safety mechanism that will not let the door open. Your compartment might be closed, but you could be having a mechanical problem with the compartment that would cause the safety mechanism to come on. Simple, but could just be it.
