When the car's faucet-shaped yellow light is on, it indicates that the engine (exhaust system) malfunction indicator light is illuminated. Below is relevant information about the car's faucet-shaped yellow light being on: 1. Different scenarios of the car's faucet-shaped yellow light being on: If the faucet-shaped light turns off a few seconds after starting the engine, this is a normal system self-check. If this yellow faucet-shaped light remains steadily lit, it may indicate a fault in the exhaust system. If the light flashes intermittently, it suggests engine misfire or catalytic converter damage. 2. Reasons for the car's faucet-shaped yellow light being on: Main causes include poor fuel quality not meeting standards, spark plug carbon buildup, oxygen sensor malfunction, engine knocking, damaged coolant temperature sensor, or engine cylinder misfire. 3. How to respond when the car's faucet-shaped yellow light is on: If the car's coolant temperature gauge and oil pressure warning light haven't activated, the vehicle can still be driven but must proceed with caution at reduced speed, seeking the nearest auto repair shop for inspection. If the coolant temperature is too high or the oil pressure warning light also illuminates, and obvious vehicle malfunction is detected, immediately pull over and request roadside assistance.
