Can You Still Drive When the OBD Light Is On?

You can still drive when the OBD light is on. Here is more information about OBD: 1. OBD is the On-Board Diagnostics system, displayed on the dashboard as a wrench-like symbol, also known as the engine fault light. 2. Another important function of OBD is to continuously monitor the engine's operating conditions and check whether the vehicle's exhaust emissions exceed the standard. If the emissions exceed the standard, a warning will be issued immediately. Reasons for the OBD light being on: Vehicle emission fault. Note: In Beijing, according to the "Beijing Air Pollution Prevention and Control Regulations," if car owners do not address the emission exceedance promptly, during the vehicle inspection, a general diagnostic tool can detect the mileage driven after the light came on, and they may face penalties during the annual inspection.
A few days ago, the OBD light in my own car came on, which gave me a start, but I was still able to drive it normally to the repair shop. This light usually indicates an issue with the emissions system, such as a faulty oxygen sensor or a loose fuel cap. If there are no other symptoms like engine shaking or smoke, driving a short distance of a few kilometers for inspection should be fine. However, if the light is flashing or there are unusual noises, you should stop immediately and not move the car, otherwise, you risk damaging the catalytic converter or incurring unnecessary expenses. I keep a cheap OBD scanner at home, costing just a few dozen bucks—plugging it in to read the fault codes gives a preliminary diagnosis. Simple issues like a loose cap can even be fixed by yourself. Don’t underestimate this; similar situations happen often. Preventive measures like regularly changing the air filter work well. Delaying repairs for too long can also increase fuel consumption, which isn’t cost-effective.
