Resetting the Check Engine Light in Your Toyota Tundra

2 Simple Methods

1. Pop the hood of your Toyota Tundra and locate the battery.

2. Find the negative terminal, which has a black cable attached to it.

3. Loosen the nut that secures the negative terminal using a wrench.

4. Pull the negative cable away from the terminal and wait for 10-15 minutes.

5. Reconnect the negative cable to the terminal and tighten the nut.

6. Start the engine and check if the Check Engine Light has reset.

1. Purchase an OBD-II scanner from an automotive parts store or online retailer.

2. Plug the scanner into the OBD-II port located under the dashboard.

3. Turn the ignition key to the "On" position but do not start the engine.

4. Follow the prompts on the scanner to select the option to reset the Check Engine Light.

5. Once the reset is complete, turn off the ignition and start the engine to check if the light has cleared.

The Check Engine Light can illuminate for various reasons, including:

- Loose or disconnected gas cap

- Faulty oxygen sensor
