What is the method to clear the engine malfunction indicator light?

Engine malfunction indicator light clearing method is: When the engine malfunction indicator light is on, 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 completing the above steps, check whether the engine malfunction indicator light on the dashboard is still on. It should be noted that when the engine malfunction indicator light is generally on, it cannot be manually cleared. Usually, it can only be cleared after troubleshooting with a fault diagnostic tool at a 4S shop. The method mentioned here is only for false engine malfunction phenomena. If it is ineffective after trying, it is recommended to go to a specialized repair shop for inspection and clearance.
Last time my check engine light came on, I quickly bought an OBD scanner to try DIY clearing. After connecting to the port and reading the trouble codes, I found a minor issue with the oxygen sensor; after replacing the new part, I easily cleared the fault code and the light went off. This saved me a lot of money, no need to go to the repair shop, the tools are cheap to buy online, and I also learned some car knowledge. The key is that you must fix the problem before clearing, otherwise the hidden danger is greater, such as emission system or ignition coil failure may lead to major repairs. Now many apps can be used with scanners, I suggest car owners to prepare a set of tools for daily inspection to prevent other minor problems. Remember that clearing the code is the last step, first find the root cause to avoid repetition.
