I have read a lot on here about it, and before i drop some money at a mechanic i was gonna see what y'all think. I have a 2008 6.4 fx4 with 101,000 miles. I filled up and drove and drain light came on, shortly after the wrench appeared. I drained it underneath and a steady stream flowed out, and nothing changed. The truck is in limp mode and won't go higher than 65 ish. I ran code and it says p2269 which water in the fuel code. My question is can i delete code and see if it gets out of limp mode(will it?). I changed the filters yesterday and the lower filter had brownish gunk built up all over it. I cleaned out housing and lid. it has a steady flow of diesel but light remains on. Will it go off if fixed or do i need to clear code. Do i need to take in, i just don't wanna have to mess up that fuel pump. What y'all think.

 

Pull the sensor and clean that off as well.

When you pull the engine mounted filter did you look in the fuel bowl for metal and gunk?

Also how often do you change the filters? Should be doing so around 10K miles using only oem filters.

 

Senix covered it well. You should also drain HFCM monthly depending on your fuel usage.

 

Check the sensor well they use a conductivity type sensor that sets off when water connects the electrodes. could have gunk built up on em. so clean it up real nice and try again.

 

can someone tell me how to change and clean the sensor. I do not want to mess anything up.

 

Let me see if I can find my figures of the assembly it will give you the right idea don't hold your breath all my files seem to have walked off

 

sensor is just to the right of the yellow handle.

 

The right side as in to the front of the vehicle.

 

Right, should have explained that better.
