Kubota MX 4800 engine codes

[NS kubota]

Has anyone had the codes come up on a Mx4800, Po606,po627 & po629? Codes just came up today while tractor was running at idle, not sure if that had anything to do with the codes. Thanks in advance.

PO606 is a low voltage issue. In other words, the ECU did not see 12v or more for a certain time. There can be several causes for the 606. One, low battery, usually after sitting a period of time without being started. Then when you crank the engine, the ECU "sees" lower than expected voltage, which throws a code. Two and less common (but still very possible) corrosion in the ECU connector.

The other 2 codes I don't remember off the top of my head. I "think" that they're fuel pump codes, but I am not positive-and they may be related to low voltage. But 606 for sure is low voltage and is common.

Thanks lugbolt I will idle up the tractor to charge better and see if the codes go away.
