Title: Need help with DELP codes 3,23, & 25
Post by: DannySquibb on October 01, 2023, 02:06:19 AM
I bought a used Yager GT200i online. It runs like crap, especially until it warms up. It gives three separate engine codes.

#3  P1120 TPI adaption fault

#23  P0136 O2 sensor circuit malfunction

#25  P0171 Close loop fault

Can anyone give some advice? Could they all be related to the same problem, or bad part? Where can I even get parts for this scooter? I can only find some cosmetic parts on Ebay.  Thank you very much!
