Your car’s engine computer sends a signal to the dashboard when the “Check Engine” light comes on, alerting you to a problem. Minor or large issues, such as a malfunctioning gas cap or misfiring engine, can cause fires. The most common cause of a check engine light is an issue with your car’s emissions systems, which can have an impact on your vehicle’s performance.
A pricey repair may be necessary if you ignore the warning light. As a result, it is imperative to pay close attention to the light indication. Ignition coils, fuel injectors and thermostats are just a few of the parts that may need to be replaced in your car.
Using the code generated by the check engine light, a mechanic can determine what’s wrong with the vehicle. Methods for resetting your Prius’s check engine light are available for models from 2004 to 2010.
The Odometer Technique
To reset your check engine light and cure your car’s issues, follow the methods outlined below:
It will flash 000000 on the odometer when the dashes turn to the right. The lights will then be turned back on and reset.
Use A Scan Tool
Using a scan tool, connect the On Board Diagnostic connector under the steering column to your car’s ignition switch and begin the process of diagnosing the problem.
It is imperative that you switch off your car’s radio before attempting this procedure. To display the error codes, which are a series of numbers and letters, use the scan tool’s read button.
The engine light will go out when you hit the erase button on the scan tool to delete the error code. Additionally, you should keep track of the codes and understand what they mean so that you can fix your vehicle properly.
Disconnect Your Car Battery
Unplugging the battery while your car is running is also known as the hard reset approach. When you’ve finished disconnecting the battery, apply the brakes to burn off any remaining electric energy in the car’s capacitors.
Before reconnecting the battery, you should wait for fifteen minutes. Leaving the battery disconnected for this long assures that when the battery is restored, your car’s system will be entirely reset.
Turn the Ignition On And Off
You should place the key in the ignition and turn it on and off three times, with a one-second gap between each one, using this procedure. Drive the car to see if the light has been reset once you’ve done this.
If the car has a slight problem, it might also reset itself. As you drive, the computer system will recheck and correct the problem.
