Multiple Codes, 771, 352, 353

Doosan G30P-5

Doosan G30P-5, pulled the following codes,

771, 352, 353. Truck seems to run fine, but the check engine light is on and worries me.

Hoping for a code definition and maybe I can fix it from there.

thank you!

352 and 353 indicate MAP sensor issues,damaged wiring component failure ect, however 771 is FTV valves (or dither valves) or attached vacuum hose problems. Possible plugged orifice on side of mixer.
Make sure all vacuum hoses are leak free, confirm the PCV valve (very critical) and spark plugs are new.
Resolving 771 fault may eliminate other faults.
