AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question I have a 2001 Toyota Sienna with 128K miles. I noticed a slight shifting problem over the past few months, but after having a new mass flow sensor installed, oil and transmission fluid changed and brakes re-done at 120 miles, everything seemed ok,,, for a while. Today, the "brake" light, "ABS" light, "TRAC OFF" light and VSC light came on when the car was shifted into drive; during this time the car runs but is slow to accelerate and revs high. The speed odometer also stays at zero. The car did jump once and all light went off and the speedometer then worked; when I stopped at a light, the warning lights came back on and the same shifting, acceleration, revving, and speedometer problems returned. What's the cause and cure?
Answer You'll need to have a diagnostic scantool connected to see what the trouble codes are, without knowing the trouble codes I don't know where to start in helping with this. Anytime warning lights turn on it means the computer for that system has seen a problem so the first step is to retreive any trouble codes that are stored.
