L3301

[Jptcuda]

On my L3301 I have code PO563. This came on one cold winter morning when I attempted to start it. I charged the battery and she fired right up. Been running good since. But still have code PO563. Any way to erase it? I tried disconnecting battery but didn’t help.

PO563 is a voltage issue

check the battery voltage with the engine running you want to see 13.5-14.5v. More than that may set P0563.

if battery voltage with engine running tests ok, you may be looking at an ecu issue or wiring issue
