Reply To: Hyosung gt250 efi ( 2008 SENTEC ) sensor replacement
Lamda Sensor , and certain EFi sensors actually come from Hyosung MS3 250 Scooter (which is a super rare scooter in this country)
I’ve ever only worked on a sentec bike maybe 3 times , as simon said , never saw a TPS module that’s why i wanted to see your pictures as to where the TPS is.
It might be my eyes but i see 1x air sensor (Delphi type) on one throttle body, if it says “Delphi” on it. The “Mini Harness” that is connecting the throttle body sensors will have numbers like 12345 (DEL) , then it means (DEL) for Early Delphi unit. with a green tag , daewoo is yellow tag most of the time.
So have a Sentec GV harness , I have not found any other compatible harnesses. GV is harder than GT. Sentec is for Sentec. However it is possible to find yourself some sensors from a 2007/2008 GT250 (only one) , as after 2009 it was all Daewoo & Delphi afterwards
