Looking to order a throttle position sensor, for a 2001 RC. On the honda parts nation web sit the only thing I see is the sensor map (SENSOR, MAP (Honda Code 6395339) on their web site is this the throttle position sensor I need.

Unfortunately the throttle position sensor only comes as a part of the entire throttle body assembly.

The throttle position sensor is installed and calibrated with the throttle body assembly.
So if the TPS goes bad, you'll have to install the entire throttle body assembly.
If you try to swap out the TPS from another throttle body, there's no procedure to calibrate the TPS.

Well code 11 is the speed sensor or wiring while 8 is TPS related.
Have you checked that it may be oxidation on the connectors or have you checked the TPS voltages per the service manual?
Oxidation can create a resistive load across the contacts and affect the voltage readings.
I know my bike had oxidation on it's connectors when I replaced my wiring harnesses last year (due to previous owner stupidity). One connector had contacts that were green due to corrosion. That's why I liberally dosed all connectors with dielectric grease to ward that off.

Got the RC back from the mechanic today and rode around for about an hour with out the FI light coming on so problem fixed. Mechanic stated that a wire running to the ECM was loose, because the ECM wasn't secure in the tail section of the bike. Thanks for all for the info.

A Tps Should Have A 5 Volt Referance. We Should Be Able To Be Calabrated With A Volt Meater If You Know The Base Setting. Most Are .5v To.99 Throtle Closed. Sorry About My Bad Spelling Im A Mechanic Not Spelling Teacher. Also Wtb Sp2 Owners Manual And Shop Manual.
