2019 kymco uxv 700i engine light comes on intermittently
« on: January 16, 2024, 09:34:26 PM »
My UXV 700's engine light comes on and turns off for no apparent reason.  The oil is full and pumping, it has coolant and it happens when the engine is cold.  I read something about codes but I don't have any way of knowing how to find that out. 
Any help would be greatly appreciated.

Good morning - welcome to the forum!

Dealer no help?, or?

And, I'm feeling a little peculiar.

Try to:
-detach both battery cables for a few minutes (hold them together a couple of seconds)
-unplug/replug all sensor connectors
(cranksensor, TPS 2x, MAP -sensor, ECU,.....)

Try ECU  sync:
-ignition off
-throttle once full open and close
-ignition on
-for exact 8 seconds throttle full open
-throttle close
-ignition off

Jump start battery from a car, does it last ?

This 700 motors are known for failing CPS (CrankPositionSensor) and faulty Camshaft Position Sensors, both  going south at early kms.

I never found a dealer that was willing to offer advice or help to a diy-er except, bring it in, we’ll take a look.  And, short of renting a trailer I don’t have anyway to get it there.

Sorry but, were you serious about all that.  I may not be an experienced mechanic but that sounds a little out there. 
Again, I’m sorry.

Ok thanks.  I’ll print his response and see if I can figure this out.

Good plan. If you get stuck, post back on here with as much detail as you can and I’m sure someone more mechanically adept than me will help! They love a challenge!
