#57 of 126 VSC and Engine Lights on
Mar 28, 2008 (6:13 pm)
Have a 2004 Sienna XLE AWD with 81K miles, yesterday the VSC light came on followed by Engine light a few minutes later. Stayed on most of the day then went off.
Back on this morning, so off to Toyota Dealer for service and check.
They checked codes and said C1246 meant need to change ABS actuator $3,000!!!
Also code P0037 - B1 S2 - another $300. Thats nearly 10% of what I paid for the vehicle.
Needless to say I'm getting another opinion before I splash the cash.
Any idea s?

I had the same thing today. The speedometer stopped working on my 2004 Sienna with 57,000 miles. The VSC, tire pressure, brake, and ABS warning lights are on. Dealer says it's rare, but the ABS actuator assembly needs to be replaced. The part is $2,815 and with labor it will be $3,280.
This is my 7th Toyota and I can't believe they are serious. This is why I buy a Toyota, so I don't have these issues. What happened with yours? Anybody else?

Just dropped off my 2002 Sienna after driving will all 3 warning lights on for a while. Lights on from 2 issues. First is Air Fuel Ratio Sensor, about $400. Secons is ABS Actuator Assembly, about $2000. I'll fix the first and hold off on the 2nd for now. We have never had problems will our Toyotas, although I'm hearing other family members with Siennas are now seeing the same issues once the car gets over 70,000 miles.

Had the same problem. First Toyota agent diagnosed Oxygen Sensor problem and Master Cylinder Pressure Sensor - I too got told it would be over $3000 to repair.
Having been assured that there was no safety issue driving with the warning lights, I departed and drove around for another few weeks. Then I went to Toyota agent number 2. They diagnosed differently - they did pick up on the Oxygen Sensor but came up with another item also. At that point I told them of my previous diagnosis and suggested that they actually have no idea what the problem really is and just want to replace components on my coin. They took exception to my allegations, and asked to keep the car for another hour (I stayed and waited the whole time - wanted to keep the pressure on) After 90 minutes they said their head mechanic was sure it was only the Oxygen Sensor and that this fault was creating the other error codes in the computer system. So they asked for permission to replace the sensor for approx $300.00 - I said go ahead. Sure enough, after another 80 minutes they came and said all was well!!
Anytime a computer system fails and shows multiple errors at the same time, don't trust it.
Hope this helps someone - it appears that this oxygen sensor is the real culprit, also I can now drive on 87 fuel without pinging again - don't know if its related, but after the first 30,000 miles my 2004 Sienna awd started pinging when cruising along a level road at 40 ~ 50 mph. Toyota agents were no help, solutions proposed varied from "induction service" to run 91 or 93 fuel. So for the last 50,000 miles I have paid the extra cost for 93 fuel, but no longer, I'm back to 87 and no apparent problems......

Bummer, first problem with my 07. Code reader says it's a P0328 - Knock sensor 1 circuit high input bank 1 or 1 sensor.
Bad knock sensor?
It's going to the dealer tomorrow, but if anyone has seen this please chime in.

I didn't get an answer at all - but get this...it turned out to be some animal chewing up my wiring harness! They found chewed up wires and acorns stuff all over the engine bay, and my van's only about a year old!
$680 or so after I begged for a discount, and not covered by warranty.
#64 of 126 SRS Warning Light
Sep 20, 2008 (12:21 pm)
In the past week my 2006 Sienna LE has the SRS (Airbag) Warning light on, intermittently. When it is on it seems to be on most of the time but occasionally turn off. It is almost in a timely manner but have noticed a somewhat random cycle. Should this light be a solid on or is it meant to flash? There has been the odd time that the light has not come on but it is not very often.
I bought an OBD-II Scanner today and found there are no codes present and erasing the computer doesn't turn the light off. Is there any way of resetting the warning light or is there another scanner present to look into the system. Dealer told me they have to scan the van ($100) to determine what is wrong and then do whatever fix is necessary. My 3 year warrenty expires the end of the year. I don't think I should have to pay anything if it is under warrenty especially for something as dumb as these darn warning lights.
Are there any known issues with this system and what has been the resulting problems?

I always thought a solid light was a warning, a blinking light was something more serious and you should not drive it.
As to whether the warranty covers it - it depends on what caused it.
Look at my case above - chipmunks chewed up my wiring harness. This is very clearly not covered by warranty, even though I thought it would be (before I knew the cause).
So I guess the answer is a big "that depends". If it's caused by a failure that is covered by warranty, then it should be free.
If my chipmunks moved to your car, and started a buffet in your wiring harness, then no, it's definitely not covered.
Having said that, the airbags are definitely under warranty, so as long as the problem is limited to that part of your vehicle, I think it should be free.

I bought an OBD2 scanner and it told me nothing. No codes present. I then read somewhere about a reset procedure. I figured if the problem is real the light will reappear. Thus I reset the warning light and it has been a week with no reoccurance. With all the electronics in these vehicles these days there are bound to be small glitches and the computers will always latch on and hold them even though they are not problems with the vehicle.
Just saved myself $100+ and who knows how much more potentially and most of all, all the hassle and aggravation to/from and at the dealer.
