If the check engine light is flashing the engine is misfiring. Most likely a bad ignition coil.
On the 1999 Toyota Sienna with a 3.0L engine, the number 1 cylinder is located at the front of the engine, closest to the timing belt. The cylinders are numbered from front to back, with number 1 being on the driver's side. This means that the firing order starts with the number 1 cylinder and continues back to number 6 on the passenger side.
A bad relay switch could be the culprit if dash lights remain on after engine starts in a Toyota. Cold weather can also cause these lights to stay on after the engine starts.
If you remove the large (3-4" diameter) rubber tube that starts at the airbox and ends at the engine intake, you will see the throttle plate a couple inches inside the bore of the throttle body (where the hose was attached).

After 50.000 miles or so. Also if the car starts to use more fuel than is normal, or if the engine starts to lose power or if the engine starts to get too noisy.
To test the starter relay on a 2000 Toyota Sienna, first locate the relay in the fuse box (usually under the hood). Use a multimeter to check for continuity by removing the relay and testing the terminals; a good relay will show continuity when the relay is energized. Alternatively, you can swap it with a similar relay in the fuse box to see if the vehicle starts. If the relay is faulty, it will need to be replaced.
you can check your engine codes of the module. Is it seized up? Is your engine getting hot? The module will show pending codes even if your "check engine" light isn't on. Another way to check is a little more simple... 1. take your radiator cap off. 2. do this when the car is cool to avoid injury. 3. turn your car on and let it idle for 10 minutes. see if the water in the radiator starts moving. If it doesn't and your engine temp. gauge starts to rise above normal operating temperature, then you have a faulty thermo stat.
The word that means brown tan and starts with the letter "s" is "sienna."
