Throttle Sensor Adjustment:

To do this modification you need to put the bike in diag mode:

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).

On the digital display select 01 (throttle position) and make a note of the number on the screen. It should be between 16 - 18.

Now locate the throttle sensor, its on the right hand side of the bike behind the cylinder.

Slacken the two bolts indicated in the above photo. Using a T25 Torx.

If you rotate the sensor clockwise/ anti clockwise you will see the number of the digital display increase and decrease.

Set the value to between 15 & 18.

hello ,i hope this might be of some help.
The fuel injection uses the TPS to indicate throttle opening, so it can be adjusted to increase the amount of fuel without increasing the amount of air. The results are a richer mixture which should smooth any surging ,as the bike is run very lean for emission purposes and results in the surging some people are experiencing

TP - Throttle Position - This sensor provides input signals to the ECM as it reacts to throttle shaft rotation, telling the ECM where the throttle is, as well as if it's opening or closing, and how fast it's opening or closing. It is at the rear end of the throttle blade

Ahaaaa.... So thats why! Thanx a lot Buck

So is it safe and must to increase the value to 26???The only mod i have is a K&N filter....

Do get richer mixture by adjusting the throttle position sensor?

Whats the gain about adjusting it?

Is it when your opening the throttle you will notice the difference?

Buck says it will smooth surging, an d Kev says that it wil surge more....
Confused....

I will bow to Kevs knowledge as my info is not based on personal experience,but from technical literature.

Try it, set the TPS to 26 ride it for a few days, then set the TPS to 16 then ride it again.

With my fueling mod, setting my TPS to 16 did improve my surging as setting it to 26. Give Fridayman
a PM as he has already tried this experiment.

Hi,

I have done a bit of playing with the TPS but no luck. I had it changed two weeks ago and still surges. No change with it at 26. (CO=15). Back now at 17. (XTR - May 05)

I read in the Spanish forum that there are two types: A1 and A2. Mine is A1, it seems that A2 goes better. So I phoned Yam Spain today and they said they wouldn't know...

Can anyone confirm about the A2 TPS? Many thanks in advance.

Cheers,

FH
