3 Answers
The methods to reset the engine fault light on Chery Tiggo 3 are: 1. Start and turn off the vehicle three times consecutively; 2. Turn off the engine, disconnect the negative terminal of the battery, wait for 30 seconds, reconnect it, and then attempt to start the engine; 3. Visit a professional repair shop to use a fault diagnostic tool for troubleshooting, after which the light can be reset. Taking the 2020 Chery Tiggo 3 as an example, its body structure is a 5-door, 5-seat SUV with dimensions of 4420mm in length, 1760mm in width, and 1670mm in height, a wheelbase of 2510mm, a fuel tank capacity of 55 liters, and a curb weight of 1358kg.
My car is a Chery Tiggo 3, and last time the engine malfunction light also came on. I was quite anxious, but as someone who often tinkers with cars, I suggest you don’t panic first. That light usually indicates the car’s computer system has detected an issue, such as a sensor malfunction or ignition system disorder. To resolve it, the simplest way is to buy an OBD-II diagnostic tool—a cheap one for a few dozen yuan will do. Plug it into the diagnostic port below the steering wheel, connect to a mobile app to read the trouble code, and identify the specific cause, like a faulty oxygen sensor. After fixing the problem, use the tool to clear the code, and the light will turn off. Don’t try resetting it by disconnecting the battery’s negative terminal—though it might work temporarily, it could affect other settings, like the car radio. Regular maintenance, timely oil changes, and avoiding frequent light triggers are key for safety. If the issue keeps recurring, it’s better to get it checked at a 4S shop.
As a regular car owner who just started driving a Chery Tiggo 3, I got nervous when the engine malfunction indicator light came on and immediately asked my friend about it. He said this light is no trivial matter—it could indicate potential engine issues that need prompt attention. The safest way to resolve it is to visit a professional repair shop or a Chery after-sales service center. They use specialized diagnostic tools to read the OBD system's trouble codes, identify the root cause (such as a faulty mass airflow sensor or fuel system issues), and clear the codes after repairs. Don’t attempt quick fixes like disconnecting the battery, as this could disrupt the car’s systems and even cause new problems. I also learned that when the light is on, fuel efficiency drops, increasing consumption, so don’t delay. Regular vehicle checks and scheduled maintenance can help prevent such issues.
