How to Reset the Check Engine Light in a 2001 Toyota Tundra

by Jonathan Shaffer

After having your Toyota Tundra repaired, the check engine light may remain on until you manually reset it. The light itself is a warning system built into the vehicle to alert the driver that there may be necessary maintenance needed on the engine. Along with the light, the vehicle will send out a numbered code that most auto parts stores will interpret for you at no charge with an auto code reader.

Open the hood of your Tundra.

Locate the black, negative terminal of the battery marked with a "-" sign.

Use a pair of pliers to unhook the negative battery cable by removing the nut that holds the cable in place.

Wait five minutes for the truck's computer to fully shut down and be ready for a hard restart.

Reconnect the negative battery cable to the negative terminal and secure it with the nut.

Start your Tundra and verify that the light is off.

Tip

  • If the check engine light remains on after this procedure, there may be another code that needs to be addressed.

Warning

  • Never touch the battery's positive and negative terminals at the same time as this will result in an electrical shock.
