Here is the quick and easy way to do a TPS reset on any 2008+ fuel injected Buell. (From the Directlink guide)


quote:

1. Turn on the key.
2. Set the kill switch to the run position.
3. Don't start the engine. Rotate the throttle from fully closed (gently held closed) to fully
open (gently held open), and then back again to closed (gently held closed).
4. Repeat 3 times. Hold at each stop (fully open, fully closed) for 1 full second.
5. Turn the key off and back on.
6. If you connect to Directlink, a fully closed throttle should indicate between 3.7 to 4.2 degrees. If it
doesn't, repeat the above steps.




According to the Electrical Diagnostic Manual, the output signal from the TP sensor varies from:
• Approximately 0.3-1.0 Volts at idle (closed throttle).
• Approximately 3.5-4.5 Volts at WOT.

my svc manual says to do the following:

Manual TPS Reset
1. Repeat three times:
a, Turn the ignition switch from Off to ON.
b. Roll the Throttle wide open and hold for one second.
c. Close the throttle and hold for one second.
d. Turn the ignition switch off.

Tried this many times and it didn't work. I max out at 78%. Suggestions.

Getting back to an old post: doing a TPS (Throttle Position Sensor) reset:

In the above posts, the TPS reset procedure is similar, but there is one significant difference between the 2 posts

First method states to roll the throttle to WOT, hold, and roll back to closed – repeat this part three times. Then turn the ignition/key off.

Second method states to roll the throttle to WOT, hold, and back to closed, and then turn key ignition/key off. Then to repeat this step two more times (roll to WOT and back to closed and turn ignition/key off).

Which is correct?

Thanks.


(WOT stands for Wide Open Throttle)

Per BWB member D_Adams, the first TPS method discussed above is correct. The TPS reset procedure is as follows for (I believe) all Buell 1125 models. From BWB member D_Adams:

For DDFI­3 and DVCS only (2008 and later Buell and all EBR products):
1. Begin with the ignition key off, run/stop switch in “Run” position, and throttle
closed.
2. Turn the ignition key on; do not start the motorcycle.
3. After at least one second, hold the throttle fully open for one second.
4. Release the throttle and allow it to snap closed.
5. After at least one second, hold the throttle fully open for one second.
6. Release the throttle and allow it to snap closed.
7. After at least one second, hold the throttle fully open for one second.
8. Release the throttle and allow it to snap closed.
This completes the TPS zero process. At this point, you can turn off the ignition or start
the motorcycle.
