How to Clear the Engine Fault Light?
2 Answers
Methods to clear the engine fault light: Start and turn off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. After performing the above methods, check whether the engine fault light on the dashboard is still on. Generally, the engine fault light cannot be manually cleared. It usually needs to be eliminated by using a fault detector at a 4S store after troubleshooting. The methods mentioned here are only for the false fault phenomenon of the engine. The engine is a machine that can convert other forms of energy into mechanical energy. It was born in the UK and can be used as a power generation device or refer to the entire machine including the power device.
I often work on my car myself, and the simplest way to clear the engine fault light is to use an OBD scanner plugged into the car's port. You can buy one online for just a few dozen bucks. After plugging it in, turn it on to read the fault codes, check what the issue is, and then select the clear option—the light will go off. But don't celebrate too soon; the light usually comes on for a reason, like a clogged fuel line or a faulty sensor. After clearing it, you must check the car—try starting it or taking a short drive to see if the light comes back. Last time my light was on due to an emissions issue, and it didn’t return after clearing, but if left unfixed, the light might reappear quickly. Make it a habit during regular maintenance to avoid small problems worsening. DIY saves trouble, but if you're a beginner, watch some tutorial videos first.
