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.

Step 1

Open the hood of your Tundra.

Step 2

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

Step 3

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

Step 4

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

Step 5

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.


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


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