Can You Still Drive with the Exhaust Malfunction Light On?

You can still drive with the exhaust malfunction light on. Here are some precautions regarding vehicle fault diagnosis: Diagnostic conditions: Diagnosis, testing, and troubleshooting must be performed under absolutely safe conditions. When using specialized diagnostic equipment, avoid operating it alone. Avoid disassembly: During vehicle fault diagnosis, try to minimize disassembling parts to prevent new faults or damage. Fault testing: Do not conduct prolonged or repeated tests on faults that may harm the vehicle's assemblies or components. It is advisable to have the vehicle inspected and repaired at a 4S shop or auto repair shop. Otherwise, the fault may worsen, leading to greater losses.
I usually enjoy driving to and from work, but the other day the exhaust fault light suddenly came on, which was really worrying. I know that when this light comes on, it usually indicates a problem with the exhaust system, possibly a faulty sensor or an exhaust leak. Safety first, so I immediately pulled over and called a friend at the repair shop. They advised against driving too far, especially on highways or long trips, as the issue could worsen, potentially causing the engine to stall, exceeding emission standards, or even getting flagged by traffic police. Later, it turned out to be a faulty oxygen sensor, and replacing it only cost a few hundred bucks. If the light comes on, it's best to have a professional check it out as soon as possible and not push your luck—after all, the car is your property, and safety is more important.
As a college student, I mainly drive on weekends for outings and don't have much driving experience. When the exhaust fault light came on, I tried continuing to drive, but the mechanic later said it was very dangerous and could worsen the damage, such as ruining the catalytic converter, which could cost thousands to fix. The cause might be simple, like loose wiring, and it's advised to first check if there are any other warning lights on the dashboard. Driving slowly for short distances in the city might be okay, but avoid highways. I always look up error codes online; buying an OBD scanner costs just a few dozen yuan and can provide a preliminary diagnosis. To save money and hassle, addressing the issue promptly is key to prevent minor problems from turning into major repairs.
