Lets try this again: faulty fuel level sensor problem

Forgive me for asking but i havent really seen a clear response for this problem.

A few weeks ago my check engine light came on again. I assumed it would go away like before but it remained. The low fuel light would came on and off several times after filling up. Looked like my fuel level sensor was acting up. I finally got my tuneECU up and running and pulled the errors. It yielded

P0135 - oxygen circuit malfunction
P0353 - ignition coil 3 circuit malfunction
P1353 - ignition coil 3 open circuit or short circuit to battery
P1351 - ignition coil 1 open circuit or short circuit to battery
P0230 - fuel pump to relay default
P1231 - fuel pump relay open circuit or short ground
P0460 - fuel level sensor malfunction

I know the fuel pump is functioning properly. Only error code that seemed to make sense was the fuel level error. So I cleared those and immediately the next day on my way to work the CEL came back on. Pulled it again that night and only gave me the code

P0463 - fuel sensor circuit high input

Which again makes sense. I read somewhere (on here on the threat I cannot relocate) that "it is better to fix the sensor than replace it with an OEM one" -deano. Has anyone written a DIY for just this thing cause if so I haven't found it?

There is a problem with the sensor at full - the fix is to restrict the float from coming all the way to the top. It's only using the very bottom section anyway.
Something to physically restrict it from coming past the mid-section, like a plastic tie-wrap, is all that is required.

Or - you can go with this if you want REAL Fuel Level data.......... http://www.triumphrat.net/speed-trip...mpg-gauge.html

(in which case you can just fix the sensor input with a 47 ohm resistor and not have the sensor even be active)

The uggghh is the thought of pulling it again I guess!
Yeah, kind of a pain
There was a thread recently on siphon tubes (in Speed Triple if I recall) which might be good to get.

I tried this and it still caused the MIL light to come on with the high value

(in which case you can just fix the sensor input with a 47 ohm resistor and not have the sensor even be active)
So then I tried this fix as a lower cost fix and it has worked, I cut the wires from the sender about 5 cm from the plastic connector, soldered the 47 ohm resistor across the wires and it worked a 'treat'. Thanks DEcosse. I didn't have to drain the tank or turn it upside down to remove the fuel sender... again...

I just have to keep an eye on the distance trip meter and refill the tank with fuel after 100 miles or so to be on the safe side. I'll replace the whole fuel sender unit in the Spring.

Or again, in your case Steve, I would suggest get the FuelBot for about same price as a new sender!
(you don't really need the optional LCD display)
It doesn't use the OEM sender at all and you get the benefit of knowing what fuel level is throughout the whole tank range.
Incredible accuracy, much, much better than OEM gauge systems that use same type of float sender

@DEcosse

Does the wattage rating of the 47 ohm resister matter? Will 1/4 watt be ok? Don't wanna fry it. Right now I really just wanna take care of my CEL. That fuelbot would make a nice bday present later to myself

1/2W would be safer bet - get that at local radios shack - 271-1105

Ok I cheated lol I put two 100 ohm resisters in parallel to make 50 ohms and split the wattage across two quart watt resisters (to save me a trip to radio shack). It's still giving me a low fuel light. What is the resistance at a full tank and low? I put a meter on the sender and it's measuring like 5M ohms (disconnected of course).

Lol disregard my previous post... I thoroughly read Steventwoods post

And this photo may explain my 5M ohm reading lol the shielding on these wires are becoming stiff and brittle.
