My 2001 avalon check engine light keeps coming on.i ve changes the coils, plugs, oil, filtersju st about everthing under the hood

SOURCE: check engine light

Try the following:
1. Make sure the odometer is shown (not trip meters). Turn key to the Off position. 2. Press the odometer button AND turn the ignition key to the ON position for a few seconds. 3. You will hear a �ding� and the odometer will show four or five underscores to indicate the reset is done.

Did you buy the universal replacement sensor where you use the plug off of the old sensor and the splice kit? If so, that is most likely the issue. Had the same problem on a 2003 Avalon. Bought the ones with the plug and codes cleared. ps. Check Amazon.com, lots less expensive.

You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted

You need to have a code reader/scan tool hooked up to retrieve the code/s that triggered the engine light. You can have this done at most auto parts stores for free. Try Auto zone, Checkers, Napa, or Murray's. The engine light will eventually go out if the computer does not receive any codes after many cycles turning the ignition on and off. It will not go out if there are codes still present. After you've retrieve the code/s bring them back here and we will have a better understanding of what caused them.
