Evening all,

I'm getting the error code "P2264-00 (2F) Water in fuel sensor circuit" on the IID tool.

I've been getting this on and off now for about 6 months - finally getting round to fixing it, as it has been nothing short of annoying.

It is intermittent - sometimes it comes on when starting up on a morning - sometimes it doesn't. Resetting it with IID tool gets rid of it and doesn't come back while driving. I initially thought I had correlated it with coming on after it had been raining overnight, but now it does it in bone dry weather too with no particular pattern.

Worth noting I've had no run ins with any deep water. So far I've:
-Replaced the fuel filter
-Swapped the water in fuel sensor with a used spare
-Swapped the wiring from the sensor to the plug with a used spare
-Checked the fuse (number 18E)
-Used different fuel
-Drained off fuel (multiple times) and found no water/fuel separation

Also, if I unplug the sensor (on the loom rather than directly on the sensor), I don't get any immediate error - I get exactly the same error random frequency.


Most recently I've done continuity tests between the 2 wires on the plug back to the ECU plug - 1 came back all good (pin 11), but no continuity on the earth wire (pin 10). Thought this was strange as the error isn't on permanently. I've since cleaned up all the earth junction bolts - no luck.

Before I start ripping out the loom to unpick it, has anyone had any similar experience or can shed some light?

Cheers

Not exactly the same as your issue but close, When I got my 3.6 the seller advised of random fuel in water messages, he had taken it to the dealers who diagnose the filter housing assembly was faulty, they fitted a new filter only as the housing was $$$$. After getting a few Eronius messages I just remove the main plug to the housing, not the wire to the sensor no more warnings. 2007 TDV8 VSE

thanks for the reply

Wish I was that lucky. Tried unplugging and I get no error for a day or so, then it pops up again.

I'm no auto electrician - as the power wire goes off in another direction and seems fine when I test it, does it sound viable that a short in the signal wire and earth wire could pop up the error message?

OK so I've unfortunately (as it seems) wasted the afternoon chasing the wiring. The wiring diagram in the Wiki seems to be outdated/incorrect. See image attached - the brown/black wire coming out of the WIF sensor to pin 10 on the ECM doesn't exist. The junction SJ934 only connects pin 10 to both glow plug module controls, and doesn't tee off to the WIF sensor. The WIF sensor earths directly to the chassis with a black wire.

Any thoughts appreciated as now I'm out of ideas.

Thanks

Thanks Jimmie, can you share the link to that workshop manual/document so I can look at the other wiring diagrams?

Cheers

go topix. Pay few $ for 24 hours access and get everything you want specified for your car.

Interesting, because I've got exactly the same problem on mine - same symptons to the letter as the OP.

Today I've repalced the fuel filter - no change, and now disconnected the plug at the bottom, and the larger black connector at the top and it hasnt made any difference.

I've ordered from Maltings this:

RANGE ROVER L322 TDV8 WATER IN FUEL SENSOR 4.4 TDV8 FUEL FILTER SENSOR LR072685S

but I'm not 100% convinced its going to fix the problem permanently, but I'm not sure where else to look.

Selfishly, glad it's not just me.

I replaced the fuel filter with a Mahle part before I started getting this issue last year - can't quite remember now whether the issue started shortly after.

I've just ordered a genuine filter today to see if it helps solve - but doubt it.

Let me know how you get on with the new part Neil - is that for the whole lot; sensor and housing?

I've tried a spare sensor, wire, but not the housing.

Thanks

The part I ordered was just the wires, so the bit that plugs into the bottom and the bit into the top - not the whole assy/housing.

I'm not sure I udnerstand why the housing would make any difference, since this fault has to be electrical, but perhaps I'm wrong.

If at all possible I wonder if theres a way to bypass that sensor altogether. 2010 L322 Autobiography Black Edition

I have seen some posts mentioning replacing the housing fixing issues - the housing looks to be 'earthed' via the small 7mm? bolt that attaches the wiring to the housing - I assume it measures the resistance across the fuel from the sensor, to this 'earth' point.

But agree, not sure what could go wrong with the housing itself.

Seems some have reported just unplugging the sensor (at the 3 pin plug) works. I've got my doubts that this works with the 4.4tdv8 (certainly doesn't with mine) - maybe works with other models. As per previous posts in this thread above, the wiring seems to differ on models.

okaaaayy....bit of an update.

Last night I removed the filter and housing again - fixed the leak and fitted the small section of harness that connects to the main loom and the top and bottom of the fuel housing/filter.

and, we have a result. no errors or restricted performance messages - all good in about 40 miles of stop/starting hot/cold/ giving it a bit of welly etc.

Fingers crossed, but its looking positive.

Glad to hear it mate,

Actually I've also had some success too finally, touch wood.

I'll report back after some more testing but the error hasn't come up since I last posted. Will report back with the solution in a week or so.

I'm intrigued to hear your fix.

so far so good with mine. 2010 L322 Autobiography Black Edition

still all good Neil?

My interesting find is that if I unbolt the housing from the chassis and wedge it with some foam (so that it is electrically insulated from the chassis & earth) I get no errors. I've had it this way since I last posted with no issues.

I've made some nylon bushes/washers to bolt it back on without it touching the chassis - but this hasn't worked - error pinged up today. Not really sure what the issue is or why unbolting it completely works. May just had to fork out for a new wire and cross my fingers.
