1. Catalytic Converter: The catalytic converter is responsible for converting harmful pollutants into less harmful substances. If the catalytic converter is damaged or malfunctioning, it can cause a sulfur smell from the tailpipe.
2. Oxygen Sensor: The oxygen sensor monitors the amount of oxygen in the exhaust system and adjusts the air-fuel mixture accordingly. If the oxygen sensor is faulty, it can cause the engine to run rich, which can lead to a sulfur smell from the tailpipe.
3. Fuel Injector: If a fuel injector is clogged or malfunctioning, it can cause the engine to run rich, which can lead to a sulfur smell from the tailpipe.
4. Bad Gas: In rare cases, bad gas can also cause a sulfur smell from the tailpipe. This can happen if the gas contains a high level of sulfur.
5. Transmission Fluid Leak: If there is a transmission fluid leak, it can cause a sulfur smell from the tailpipe. This is because transmission fluid contains sulfur.
To determine the exact cause of the sulfur smell, it is recommended to have the vehicle inspected by a qualified mechanic. They can diagnose the problem and recommend the appropriate repairs.
