The TPS voltage range is shown in the manual and also the wires at the ECM as to where to read those voltages. Stick a meter on those pins and run the throttle as the procedure states. If the voltage is within the specs you should be good to go, if not take it in for a reset. |

This is why I am glad I work at the dealer I get to take home the Scanalizer and have a garage party.  |

SRL,
Just having a reading in those specs does not mean you are good to go. It means the TPS is receiving and sending the expected voltages from and to the ECM.
The range is given to let you diagnose problems and find if you have a bad TPS, a starting point. It can read between the ranges and you can "assume" (the TPS not the ECM setting) it to be OK and move on to the next procedure when a problem exists.
The ECM must know what the exact voltage is at zero throttle to run at peak performance.
In about a million pages of discussion here, if a new ECM is installed, a new TPS is installed, the TPS is removed and/or changed location and at service manual stated intervals you must see your friendly local Buell dealer.

Have the dealer do it. The Scan tool is there for a reason. You can't get an acurate re-set by reading those specs. |

Jeff/Rempss,
"In about a million pages of discussion here, if a new ECM is installed, a new TPS is installed, the TPS is removed and/or changed location"
I think you meant to say that "if a new ECM is installed, it must be calibrated/reset for TPS zero. In Buell-speak, "the TPS must be reset/rezeroed", which in truth means that the new ECM must be programmed/flashed with the TPS's voltage for the throttle closed-tight (zero idle screw contact) position. The TPS, unless operating outside of the prescribed voltage range, would not be touched.
As Spiderman says, the ONLY way to "reset the TPS" (meaning to reprogram/flash the ECM) is to have a Buell technician perform the required procedure using the proprietary scanalyzer program. |
