09 620i trouble code

i have an 09 gator 620i. A couple a days ago it felt like went into a limp mode. Its throwing a code of 1 long 1 short. Anyone have an idea what this code means.
Tore the throttle body apart and cleaned it. Changed the oil because it looked like there was gas in it. Had it at the local john deere for some work a little while ago. They adjusted the valves, changed oil, cleaned air filter, replaced the fuel pump since they broke off the original while working on it. Machine only has 340 hours . Its only been 10 hrs on the machine since the service was done. Never had any issues before i took it to them for the first time. Any help would be greatly appreciated.
​ Thank you
