I drive an 06 Sienna and have never had any issues or codes in 255k miles. The sliding doors both broke but I'm not lazy like many so I just operate them manually.

[@seikocitizenwatches]

My 2005 Sienna just had the ignition coil #4 replaced after noticing engine idled rough and losing power when accelerating. The car has been reliable over 17 years and 318K miles. This has been the most serious issue. Previously serious issues were 1 starter and 1 alternator.

I have a 2004 Toyota sienna with 198,000 miles on it. For the last four years I’ve had an engine check light and VSC check light on the mechanics at the dealership have replaced two oxygen sensors and a catalytic converter and still have not fixed the poor gas mileage and engine check lights! About a month ago I cleaned my mass airflow sensor and disconnected the battery to reset the codes. Before I did this my van was averaging about 13 miles per gallon afterword I was getting 23 miles per gallon. But now the lights have come back on and I’m down to getting 13 miles per gallon again!

Both sliding doors for me. Not TOO bad to replace, but if you mess it up once, it’s a waste of 3+ hrs and $160 part. Replacement part is cheap quality if it’s off Amazon, as expected. But I couldn’t bear to pay double for OEM and still risk messing it up.

[@haroldbrooks4235]

Awesome 🤩

[@williammurray5655]

Have you done a video on the motor mount type of PWM vacuum switch valve? I can’t seem to find any decent info on which of the three hoses go where. The switch has a port on top, that I think goes directly to air filter box. Then two ports in back. I think one of those ports is a vent and the other goes to what I believe is called the actuator. It connects to a second vacuum switching valve then the actuator. But I can’t find anything online that definitely tells me which of the two back ports on the PWM vacuum switching value is to vent and goes no where. Seems to be something I should get right on my 2008 Sienna!

[@joehill789]

I’ve had a 2008 Sienna for just over 2 years now. Have already replaced an O2 sensor, mode door actuator, both blend door actuators, heater core, crumbly plastic heater hose t-fittings, and power sliding door cable. Fingers crossed I can avoid needing the MAF sensor, or Evap Canister anytime soon.

Just had the rad 3:12 replaced in summer of 2023 for some reason my 07 Toyota sienna van blew off the rad filler neck wasn't sure what caused this issue but may have been low antifreeze or air bubbles.

[@Alex.R16]

🙋‍♂️ ok so today I did some maintenance on a 05 sienna, and when I was replacing the air filter I thought it’d be a good idea to clean the MAF sensor. And of course being a klutz, I some how disconnected one of the 3 air lines that was going to the air filter cover where the MAF sensor is screwed on to, and I heard it release air like when disconnecting an air hose from a compressor (well maybe not THAT loud). I didn’t even clean the MAF sensor, and just out everything back. Turned on the vehicle and let it idle. After like 5 min the RPM dropped to around 500 but the vehicle didn’t stall. I shut it off and tried to turn it back on, nothing. Tried a second time, and now it just stays at 500. Any suggestions how to fix this blunder??

[@triaxe-mmb]

I have an exceedingly silly question...can I add a driver side power sliding motor and such to a 2004 Sienna LE? I know the XLE has it but this LE came with full history and such so I went for it when I got one recently as a temp car till more EV options that fit my needs come on the market. But...not having a power sliding door on this side is becoming an issue...

[@pkfilseth]

Good luck! We also have an 04 Sienna in the same mileage range, and we are among the many, many unlucky people who had the front door weld break. Have been quoted $3000 to replace the door. The problem is that the door check no longer works, so the door will swing wider than you set it for, which risks banging into and damaging someone else's vehicle. Toyota was finally forced (by the sheer number of complaints) to acknowledge the design failure and fix these, but we didn't get the notice or have the problem until after the recall had expired.

[@poetrynook962]

If the power side doors fail, can you simply open and shut them manually. Will they still lock?

You can still open and close them manually, but nowhere near as easily as a manual door. We have a 2004 LE with one manual door and one power door. The manual door is super easy to operate. The power door, with the power shut off to it, is not.

I got a problem with my 2004 Sienna, maybe someone can help me? Ignition key out - rad fans start working. (Not all the time, it may happens once a day or once a week) They may start any time when car locked and alarmed. Key in, ignition ON - all good. The same thing with day light. May turn ON any time when not in use. Drain battery to zero. I disconnected day light. And disconnect fans plug all the time when not driving. This happens mostly in rain season when wet. Never in dry summer. Any idea? Thanks

Siennas are great vehicles

[@pegashus1]

VERY common problem that's hard to fix on 2004's: the driver's door check strap cup cracks, causing a popping noise when opening and closing. There was a "recall" years ago but it has lapsed. Cannot buy a replacement cup that should be welded into the door.

[@jcadult101]

Only done ignition coils out of that list. Power door cables are more common than those listed. Valley plate coolant leak on the 3.3s. And #1 is probably leaking power steering rack.

[@mcconn746]

It is counterintuitive but dirty filters actually filter our more particles than clean ones. The problem with dirty filters is that at some point they create too much back pressure or break. In manufacturing plants, they sometimes have backpressure gauges to indicate when a filter is too stopped up. Meanwhile the filter is getting better and better at filtering. The logic. When a filter is new, they have holes so air can go through. They will catch particles larger than the holes. As particles partially fill some of the holes, they catch some of the smaller particles. Bottom line, dirty filters are not the cause of MAFs needing cleaning. Of course you do need to change the filter eventually or it will make the make the fuel air ratio too rich.
