I am assuming there were no problems with this skoot b4 the installation?
Error code 11 relates to "throttle position sensor". The PCV has a wire that is connected to a wire at the throttle body, that is one of the wires for the tps .
Either that connection is not good or the connector has split the copper wires and opened that circuit...I just sent back a brand new outa the box pcv to d/j. Bike didn't sound right at start up and had abnormal glitches/hesitations at different rpm/throttle positions. Completely disconnecting the pcv allowed the skoot to run properly.
Make sure you have the correct PCV, make sure it has the latest firmware. The "remove the pcv and see if that fixes the problem" is also recommended.
