how to clear check engine light on Toyota RAV4 Fifth Generation (2019-present)

Solution

1. Preparation

• Ensure that the vehicle is parked on a level surface and the engine is off.
• Gather tools: OBD-II scanner, safety gloves, and safety glasses.

2. Retrieve Error Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port, usually located under the dashboard on the driver's side.
• Turn the ignition to the "ON" position without starting the engine.
• Follow the scanner's prompts to retrieve and record any trouble codes.

3. Inspect and Address Issues

• Based on the retrieved codes, inspect related systems (e.g., fuel, ignition, emissions).
• Tighten or replace the gas cap if it was loose or damaged.
• If applicable, perform necessary repairs (e.g., replace faulty sensors, fix leaks).

4. Clear the Check Engine Light

• With the OBD-II scanner still connected, navigate to the option to clear/reset the error codes.
• Confirm the action and wait for the scanner to complete the process.

5. Final Checks

• Disconnect the OBD-II scanner.
• Start the engine and check if the check engine light remains off.
