Can You Still Drive When the Water-Fuel Separator Alarm Goes Off?
1 Answers
When the water-fuel separator alarm is triggered, the cause should be investigated. If it's due to water accumulation, you can continue driving, but for other reasons, repairs are needed before driving. Reasons for the water-fuel separator alarm: Flashing state: The water-fuel separator is installed on a bracket near the fuel tank of the car. It separates water from fuel by utilizing the density difference between water and oil, filtering moisture from the fuel. When the moisture content in the fuel filter exceeds the limit, the water-fuel separator cannot function properly. Steady light state: A malfunction in the sensors related to the water-fuel separator causes it to stop operating due to the inability to transmit the working status normally. A faulty water-fuel separator prevents the proper removal of water during fuel combustion, which can easily lead to abnormal operation of the fuel injectors. This may result in unstable engine acceleration, lack of power, black smoke emissions, white smoke from the engine, and severe carbon buildup. Solutions: When the water-fuel separator warning light is on, you can open the drain valve under the separator's liquid storage tank to release the water. As the liquid level drops below the sensor, the indicator light will naturally turn off. If the warning light remains on after draining the water from the storage tank, the issue might lie with the water-fuel separator sensor. Use a multimeter to check the sensor's voltage, which should normally be 12V and 5V. If abnormal, and after confirming it's not a wiring or connection issue, replace the water-fuel separator sensor.
