Need to pull codes to find out what is happening. Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active. Disconnecting the battery can create other headaches and will not likely solve your dilemma. Best bet is to contact the local snap-on dealer and have him refer you to a known good shop that specializes in this technology-he will know. The " check engine light" is by far one of the most misunderstood technological advances by the public. This is an needed in-depth understanding for the public. It is a warning light that is illuminated when there is a problem affecting the EMISSION SYSTEM only. Emission system being the pollution control system. Don't get a hard on against it as it is a good thing once you understand it. One point that was brought up a a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say that about 7% of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place. After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ vastly, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights
Upon further inspection, the rear door handle assembly on the 2002 Toyota Sienna IS the same as that shown on the Find One Find All website, so never mind.
I hesitate to appear to misprize my native city
I am just replacing 2 of 3 on my 2000 Sienna, so I am willing to bet that 2001 also has 3. I am told that there is one IN the exhaust manifold, but there appear to be 3 on the Y shaped replacement part (appears to be at LEAST 3' long). I am on the sight to research exactly WHERE they are.
A person can reset the maintenance required light on a 2004 Toyota Sienna by holding down the odometer trip button. A series of zeroes will appear, which indicates that the light has been reset.
With the ignition switch in the off position, hold in the hold in the trip odometer. Now turn on your key and you will see a series of zeros begin to appear. Once that stops, your maintenance light will be reset.
red shifted
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
The object appears to move up and away from you as you shift the stage toward you in a microscope.

Toyota does not currently appear to be selling any light pickups with diesel engines in Mexico.
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
This light comes on about every 5000 miles or so to remind you to change the oil. Reset as follows: with the ignition switch in the off position, hold in the the trip odometer. Now turn your key to the on position and you will see a series of zeros or dashes begin to appear. Once that stops, your maintenance light will be reset.
