Why do I keep getting engine
oil in my airbox

And hello to you as well.

Why have you attached a quote for CODE 46 & asked a question for oil in your air box, do you want to ask a question about code 46?

What year & what model XT660 do you have?

er 1 - someone please help

hello

just recently got an error 1, the starter has made awful sound... disconected all the conectors cleaned them! but now when i turn the key, the screen is still black, and nothing happens just the parking light and stop light are working, any ideas how to fix it or maybe the ecu is dead?

i saw the question about the oil, have the same problem ( if it is a problem ), its nut much oil but still!

hi have a on going issue with my xtx 2004,a while back i took it to a SM track in south australia and come off a few times at slow speeds in soft sand and error code 08 flashed up a few times and since then bike has been having problems with 3rd gear.when riding slow-ish its ok but as soon as you accelerate the engine jerks a few times while powering up the revs change into 4th and 5th its ok
did a fault test on display and found error code
d61:30
d62:1
i did notice in sensors test 09 : Battery voltage - must be above 12.0 mine is reading 0?

Following ERROR codes DO NOT allow engine to run :
11-12-19-30-41-50 and Er-1 to Er-4
Error code 11 allow engine to continue running only if fault appears after engine start.

Error Number 30 : The bike went down - DIAG mode 08
im now picking at straws and was woundering if this would be related to my issue..it does feel electrical
have been to a coullpe of bike shops and not much help

Get error 4 when trying to access Diagnostic, same as quoted bike starts and runs normal. Any suggestion to clear error and access Diagnostic.

DIAG mode allows user to check tons of stuffs inside the electronic brain of the XT. It also allows Yamaha servicing to check previous problems too.

To access DIAG mode :

switch off Engine Run switch, switch OFF Key switch. Press both SELECT & RESET buttons and then switch ON Key switch. Keep SELECT & RESET buttons pressed for at least 8 seconds. Display then changes to "DIAG". Release SELECT & RESET buttons.
Select Diag mode by pressing again both SELECT & RESET buttons.
Select code below by pressing SELECT (up) or RESET (down).

Diag Code Number

Part I : Sensors

01 : Throttle position - must be from 15-17 (closed) to 97-100 (opened)
02 : Atmospheric pressure given in mmHg (normal is 760 - average weather)
03 : Differential pressure between air and intake pipe
05 : Air intake temperature (in Celcius)
06 : Cooling liquid temperature (in Celcius)
07 : Absolute speed (must be 000 in garage). Check with rear weel.
08 : Lean angle safety switch control - must be from 0.4-1.4 (upright) to 3.8-4.2 (horizontal). DISMOUT THE SWITCH FOR CHECKING !!!
09 : Battery voltage - must be above 12.0
20 : Side stand switch - displays ON or OFF
21 : Neutral gear switch - displays ON or OFF

Part II : ECU memory check.

60 : EEPROM error code presence - 00 means no default, 01 or 02 means default on corresponding cylinder (blinks if both cylinders).
61 : Error Code memory log - Displays 00 if no error code in memory, displays the Error Code if any (11 to 50). Display changes every two seconds if more than one Error Code in memory, then start again from first.
62 : Displays the number of Error Code in memory. To clear the memory, switch the Engine Run Switch to ON position (no backup).
70 : Check Code number, display from 0 to 255

Part III : Activators - To activate, turn Engine Run switch from OFF to ON - Engine check light is activated too.

30 : Coil 1 is activated 5 times per second.
31 : Coil 2 is activated 5 times per second.
36 : Injector 1 solenoid is activated 5 times per second.
37 : Injector 2 solenoid is activated 5 times per second.
48 : Air duct solenoid is activated 5 times per second.

Hi There I've just finished restoring an XT660X which was a CatD write off, engine was running and pretty sure engine light was off, since reassemble the light is staying, engine runs fine, it has K&N stage 3 filters and snorkel removed (std Pipes).
Carried out diag mode and these results are showing.
D3=1
D5=10
D6=11
D8=0.6
D61=30
D62=2

I have tried to understand what all these mean but filed miserably, would appreciate any ideas guys?
Many Thanks
Steve

Greeting
I have a big problem to which I hope to get an answer :)
I ride Yamaha XT660R (2009). After standing for a couple of months turned on me and on the display it showed the letter blinking non-stop while engine is running. Do not show me a kilometer watch, just letters E blinking. I drove it to an authorized service center Yamaha in Croatia but they have not found a malfunction. Guys can you help me?
