I got the owners manual out. Pretty well written, BTW. Very little Chenglish. The manual says, and I quote, "system fault coding winkle rules are as following ...".
Seems the check engine light, or trouble indicating lamp, as they have it, will "wink" out the error code for you. Comical as it may be, it's VERY useful. There is a corresponding fault code table for it also.
Mine was throwing a 13 code, which is for the Idle air control valve (IACV). I removed mine and googled the part number on the OEM part and found them for sale in China only. There was mention of it being used for an evaporative purge valve also, so I googled that also and found out that Bosch brands the exact same part manufactured by the same Chinese company for the VW Pasat. $15 eBay.
I installed the part only to find out that the problem still existed. So, I took some fairings off and got out the flashlight looking for anything obvious and low and behold there was a small black plastic cap laying on the motor. I went back to the manual to look at the other EFI components and found that the inlet pressure sensor looked to be the same size and shape. Sure enough, the cap had somehow popped off of the top of the sensor and landed on the engine. How it stayed there for 2 road trips and about 15 miles is beyond me.
Anyway, I popped it back on and everything's back to normal now. This pressure sensor controls the part that the error code pointed to. Even the trouble light went out. How's that for luck?
NOTE/Update: American Lifan contacted me on the KP club forum on FB (for KP owners only) and apologized for the issues that I encountered and sent me a new, OEM, idle air control valve from Canada. Good company, good product. Love my bike! Powersportsmax has yet to even begin to deal with the issue, support ticket still open, and I have already took care of it a week ago myself.
