What to Do When the Exhaust Warning Light Comes On?

[DeLaura]

Solutions for the exhaust warning light coming on: 1. 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; 2. The engine exhaust system warning light often comes on due to damage to the oxygen sensor in the three-way catalytic system or poisoning of the three-way catalytic converter caused by poor fuel quality. If the light comes on while driving, immediately reduce speed and drive to the nearest service station for inspection; 3. If the vehicle cannot start after the warning light comes on, call for a tow truck. If the vehicle can still be driven but experiences severe shaking, lack of acceleration power, or other symptoms, it is recommended to stop driving. This not only prevents further damage to the engine but also ensures personal safety.
