Throttle Sensor Adjustment
DISCLAIMER: YOU DO THIS AT YOUR OWN RISK AND MAY VOID THE MANUFACTURERS WARRANTY.
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 |

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? Last edited by Kev; 06-10-06 at 09:50. |

But it will make the bike surge more, as when the throttle is closed the air is shut off for an idle mixture, the extra fuel at this point will cause a run on effect & does cause a surge. I have done quite allot of playing with the TPS lately & found the best setting for my bike is 16, hardly any surge. There again I can adjust up my fuel mixture using my Fuel Mod to give me that extra power.

Hi everyone.
I was just wondering, if I had a Power Commander fitted, would I still need to adjust the TPS if using a DNA Stage 2 to make the fuel richer or would the Power Commander do this? I am tempted to buy a DNA Stage 2 filter but most advice I get is to fit a Power Commander if I do this, but they are quite expensive and I am not technical enough to do the Kev Mod. Therefore, would me adjusting the CO2 and the TPS be satisfactory as regards the fuel mixture with the DNA Stage 2? Cheers, Pingu. |

I might be wrong in saying this, and maybe Kev can correct me if I am, but I was told that the need to adjust the TPS (throttle sensor position) is to correct an improper setting of the TPS itself (frequent cut-outs, etc.) or to rectify a bike which is too lean and when this is not helped by increasing the CO1 levels at the dash.

After installing the PC I noticed another equivalent power increase to the one obtained with the stage 2 filter but I could have also lived without the PC. In my case, increasing the TPS value made the bike work really bad (tested it before installing the PC) Just my 2 cents
