Hi
i have a question about the water in fuel lamp. Last year, I have bought the car and the lamp illuminate normally, but for two months i have looked in the engine compartment and i have seen the plug for the Water in Fuel Sensor Plug is not connected to the Water in Fuel Sensor, however the lamp can illuminate

How is it going ?

Thanks a lot

regards from Germany

 

Are sure its not the fuel bowl heater that is unplugged?

 

The fuel heater and the water in fuel sensor are the same plug. I am willing to bet that the fuel heater is blown and if you plug it back in, you will blow a fuse and the engine will die.

EDIT: Look at this LINK.

 

So how's the weather in Germany? If you are wondering about water in the fuel.. just drain some into a clear jar from the hose or pipe under the engine by using using the fuel drain valve handle (yellow in color). Let the jar sit for a while and if there is water in the fuel, you will see it .

 

Thanks a lot ,

the weather is toooo cold and thanks for the tip with the valve,

best regards

 

Here is a photo for reference.
The connector you see is the fuel bowl heater connector which also carries the water in fuel signal to the PCM. Since it's unplugged, it most likely means that the heater has shorted out. When that happens, the fuse blows and everything else on that circuit is deprived of power. The PCM is one of those items so the engine will just quit running.

The fix is to unplug the connector and replace the fuse and be on your way. The effectiveness of the fuel bowl heater is minimal so most people don't even notice when it's unplugged.

The water in fuel light should only come on during the self test when starting the engine and then go off. If it stays on, then you might have some crud in that connector that needs to be cleaned. If so, then clean the connector with some electrical parts cleaner in a spray can and then seal up that loose connector to avoid future issues.

Hope this helps.

 

Nice Picture ! .. but i bet the fuel housing leaks !! lol

 

That's a new mod called "un-regulated return".
