Just take off your positive (red) wire cable off your battery for about a minut or two, then simply hook it back up and there you go no more light. By the way though all these tricks listed will only last about a week.

If it's a service req'd/check engine light, You can go to Autozone or Advanced Auto Parts and plug their computer to it and erase the light for free. But if there is still a mechanical problem that triggered the light, you'll have to fix that first or the light will come back.

Hope helped with this. Good luck (remember rated this help).

The "check engine" light will go out automatically once the problem is fixed that made the light come on.
You can take your vehicle to your local Auto Zone store and ask them to scan your Sequoia for trouble codes and they can tell you what is causing the light to come on, they will do this for you at no charge.
Good luck.

Hi,

I highly recommend you have the fault/s rectified first, before you reset the Engine Check light.

You can erase the codes (reset) by the following procedure:

  • Turn the ignition OFF and remove the negative battery cable for at least 1 minute.

  • NB: Removing the negative battery cable may cause other systems in the vehicle to loose their memory. Prior to removing the cable, ensure you have the proper reset codes for radios and alarms.

    Hope this helps....

    THIS IS HOW YOU RESET THE CHECK ENGINE LIGHT ON THE 99 HONDA ACCORD. 1. With the Car Off, Press and hold down the Odometer Trip Reset Button. 2. While still pressing the Trip Reset Button, Turn the Ignition Key half way on where all your oil, check engine lights etc.. turn on. Don't turn it as far as you would to normally start the car. Wait a few seconds and the Check engine light will turn off. 3. Turn the key back to the Off position and you're done. What a scam Honda has with the BS Check Engine Light.

    How do you turn off engine light on a 2009 Mercury Marquis


    The Check Engine light must be reset using an OBD-II code reader. Dealers have them as do repair shops. Places like AutoZone will read the codes for you, but normally will not reset the Check Engine light due to possible liability issues. You can purchase a code reader at these places to do this yourself. Make sure you get one that can read and reset the engine light. The very cheap ones cannot reset the Check Engine light.

    Check engine light on, Mitsubishi lancer


    To reset the computer, disconnect the battery for a couple minutes, then hook it back up again. This will not solve the problem if there is one. The check engine light comes on to let you know that there is a problem. If you take it to an auto parts store, they can read the trouble codes and reset the check engine light.

    The check engine light is on my 1995 Saab 900s. I can not find a techician with the correct scanner.How can I turn off the light?


    There are three ways to reset a check engine light.

    1. Disconnect the battery, wait approximately 30 minutes, reconnect the battery. This resets the cars computer which also reset the check engine light. On newer OBD (on-board diagnostic) compliant vehicles this usually does not work. See step 2.

    2. Reset using an OBD II reader. When you hook an OBD II code reader up to your vehicle, you can reset the computer using the code reader.

    3. Fixing the problem. Generally the check engine light comes on for a reason. Usually it is emission related (sensors, gas cap) or electrical (faulty wiring). In this case the way to reset the check engine light is to fix the problem

    How to reset check engine light?


    Go to your local O'Rielly's or Autozone. They will tell you the code and reset it for free. Otherwise take the negative battery cable loose for about 10 min. This will clear the ECM, but you won't know what tripped the light! Best Wishes, TJ
