I've owned this 750 hour 2017 tractor 2 weeks - it runs fine and I'm learning to cut down on idling and to keep the RPMs up to reduce PM regeneration (it's done 2 so far). Yesterday while cycling through screen displays I see a PO335. Kubota error codes I've found online don't list a PO335 but for most/all autos it's a cam position sensor. There are no warning lights lit, the tractor runs fine. Any suggestions or ideas what this might be? Tomorrow I'll try to clear the code - it's a 5 step process starting with pressing the 2 regeneration buttons and turning the key on simultaneously.
