We have a Deere 650J, When it gets up to temperature it throws an F497 engine code and goes to half power. The ECU is new and has been calibrated by dealer. Anybody ever had this problem? Thank You.
Pump control solenoid. Check the wiring at it and going to it. Last time I had one of them do that it was in an excavator and I found the wires were exposed and really work hardened to the point they were down to a couple strands each.
