How to Reset the Check Engine Light on a Toyota Corolla
To reset the check engine light on a Toyota Corolla, you can follow these steps:

2. Disconnect the negative battery cable: If you don’t have a code reader, you can reset the check engine light by disconnecting the negative battery cable for a few minutes. However, keep in mind that this method may also reset other settings in your vehicle, such as radio presets and clock settings.
3. Reconnect the negative battery cable: After a few minutes, reconnect the negative battery cable. If you experience a low idle when you hook the battery back up, it is normal and should stabilize after a short period of time.
It’s important to note that resetting the check engine light does not fix the underlying issue. If the problem persists, the check engine light may come back on. It is recommended to have your Toyota Corolla checked by a professional as soon as possible to prevent any potential damage to the engine.
