My 2007 burgman 400 is reading a C29 error code, which I see is STP sensor. How bad is it for the scooter to ride with this error. I don't want to damage anything further but would like to see if I can ride until I get this fixed. Thanks!

Thanks that makes me feel better. Is the STP sensor just for low speed idle? Either way I'm going to try to take it off and clean it if possible. Connectors and wires look good. If that doesn't work I'll order a new one.
Is the STP and TPS the same sensor?
Thanks for the info. I may take this one to a shop.Mostly PSA, always disconnect battery before disturbing computer/sensors wiring. Or follow manual.
Clean and reseat connectors 1st, do not remove and/or adjust the STPS (Secondary Throttle Plate Sensor) unless you are familiar with how it works, note/mark initial position, etc. Secondary throttle plate or valve works mostly at low to medium throttle positions too smooth out transitions, etc., but it also can affect other situations, it kinda allows the use larger bore throttle body in a smaller engine, its controlled by computer/ECM from other sensor data/input. Plenty of internet discussion on them, but most agree they must be properly set to work correctly, as in no fault codes.
BTW, some connectors on TB are identical don't mix up. Sometimes cleaning ECM connectors also helps.
Idle is controlled by ISC (idle speed control).
