I know i am going to get shot down but i have saved ££££ The water in fuel sensor keeps on coming up and the restricted performance ( yellow) come up every two /three starts . i reset all the codes and I have had new fuel filters etc and the fuel looked at and there is no water in the fuel .
So I have given up with the sensor and placed a 690ohm resistor between signal and ground and 12k between signal and sensor power on the wires going back to the ecu and for the last two weeks no warnings .
This modification works for me and if you do not think it is good then don't lambast me for doing it but it has saves the cost of a new filter housing as you can not buy the sensor separately, thus saving ££££ . 2012 Black 4.4 TDV8

This is good to know, do you have a source for the parts please, and part numbers - thx

On my 3.6TDV8 random water in fuel warnings, new filter and diagnostic by main dealers says no water but need new housing for $$$$$. I just unplugged the sensor multiplug with no issues or warnings so job done. 2007 TDV8 VSE
2003 TD6 gone.
2002 P38a gone
1999 P38a gone
1997 p38a gone
1993 VSE gone
1992 VSE gone
1966 Series 2a with V8 conversion gone

Hi misfire84 - did you use a particular type of resistor? I’m having an ongoing yellow triangle / water in fuel code and it’s driving me insane after changing the wif sensor and filter etc … wanted to try your fix before having to pay out £££££ 😭

Thanks for your advice.

The Ford Transit Housing is £30 quid, just remove the harness, its all you need

See the last few posts on this thread for more info and part numbers, I just did this for a friend the other day, 15 mins work tops

Thanks, but I have brought two genuine ones one used one new and they haven’t solved the yellow restricted performance issue

I don't think you will get a response from misfire84 as he has not posted for here for over a year, and he did not reply to me asking him about his resistor method either, good luck sorting it, for most of us it was simply the harness that needed replacing.

Ryanc --- as misfire84 is no longer responding, the resistor trick from my notes is the following :

Place a 690 ohm resistor between signal and ground and 12k between signal and sensor power on the wires going back to the ECU - let us know how you get on
