Last Updated on September 17, 2023 by Albert Duke

To reset the check engine light on a Hyundai Tucson, fix the issue or code that caused it to turn on, and the light will shut off on its own. This can be done by using diagnostic tools or disconnecting the battery.

However, it’s important to note that disconnecting the battery may also reset other systems in the vehicle. Therefore, it is recommended to use a diagnostic tool for a more accurate and targeted reset. Resetting the check engine light is a simple process and can be done at home without the need for a professional mechanic.

Causes Of Check Engine Light

The check engine light on your Hyundai Tucson can be triggered by various issues. Faulty emissions control parts, a faulty head gasket, a damaged oxygen sensor, a dirty mass airflow sensor, a malfunction with the fuel injection system, or defective spark plugs are some common causes.

It’s important to address the underlying problem to prevent further damage to your vehicle. Resetting the check engine light can be done by disconnecting the battery or using a diagnostic tool. However, it’s recommended to first identify and fix the issue before resetting the light, as it will likely turn back on if the problem persists.

If you’re unsure about the cause of the check engine light, it’s best to consult a professional mechanic for an accurate diagnosis and appropriate repairs.

Resetting Check Engine Light Without A Scanner

To reset the check engine light on your Hyundai Tucson without a scanner, you can try disconnecting the battery. First, locate the negative cable of the battery and disconnect it. Then, wait for a few minutes to allow the system to reset.

After that, reconnect the battery. This process may help reset the check engine light. It’s important to note that resetting the light may only temporarily resolve the issue. If the underlying problem is not addressed, the light may come back on.

Therefore, it’s recommended to have your vehicle checked by a professional to diagnose and fix any potential problems.

Using Scanner To Reset Check Engine Light

To reset the check engine light on a Hyundai Tucson, you will need to use a scanner. Start by connecting the scanner to the OBD-II port, following the scanner’s instructions for proper connection. Once connected, you can then proceed to reset the check engine light.

It’s important to note that resetting the light will not fix the underlying issue that caused it to turn on in the first place. If the issue is fixed, the check engine light should shut off on its own. However, if the light continues to stay on after the reset, it may indicate a persistent problem that requires further diagnosis and repair.

Be sure to consult a professional if you are unsure or if the light persists after the reset.
