Error 46
 
Hi guys,

New to the forum I've recently encountered a problem with my 08 XTX that I think kev might be able to help out.

my bike has given an error code 46, but after charging and new battery the error code still remains, the bike runs and starts fine the only problem a can diagnose is a slight high pitched whine from the front of the fuel tank area. Doesn't sound the same as the bike priming before startup? any help would be amazing thanks guys!!

just did a quick forum search using the title 'error codes'...46 = fuel system power supply not normal...

the 46 aka the Valentino code ;) is correct, but often the cause can be a faulty fuel pump, which has shown to trigger the same error code. If you can't service this yourself better take the bike to an authorized Yamaha repair centre

High pitch whine from fuel tank + Error 46 = Fuel pump on its way out

Usually caused by wear in the motor causing it to draw a larger than normal current which in turn causes a voltage drop in the FI system, and this is what causes the ECU to flag up a 46 code.

Don't fret though. Although the Yamaha price an eye-watering �550, you can split open the pump's housing and replace the actual pump inside for around �30/40. There are many sellers on ebay offering suitable pumps for XTs. DO NOT go to a dealer because all they will offer you is a complete Yamaha pump assembly, plus fitting/labour, which will more than likely end up heading the direction of a four figure sum!

Oh but my bike is a 06x. Will this pump fit my bike?

nikroc 14-01-17 16:28

tbh I thought he engines were the same..but you could ask the seller otr do a ebay search..

Although I've not had any error codes, the fuel pump on my XTX will sometimes whine when turning the key on when it's cold out or after I've filled up the tank. I bought a used pump that came out of a Tenere on eBay for �25 last summer and planned to fit it this winter but still haven't got my winter hack ready so the XT is still in use.

When I do get around to it though I'm wondering whether I should replace the o-ring between the pump assy. and the tank. I know I should really but it's �20 from Yamaha!!!

nikroc 14-01-17 22:52

replace but take original and if poss any parts that it fits to a bearing/transmisson place..if it costs �1.00 you either been robbed or got a bargin..

The internal part of the fuel pump assembly (the actual pump) is identical for all XTs and the MT-03. So yes, this one will fit.

Pete, was it definitely a 3mm section? I ordered a couple of these o-rings the other day but found the section was smaller than on the original - it didn't look like it would seal properly so I ended up reusing the original o-ring.
