Got a New Holland L218 HEM485500 JAF0L218HEM485500 Code 3973 EGR Valve Energizing Duty Error. Anybody know anything about this?
Hopefully someone with New Holland experience and information will chime in soon. The best I can tell is that it appears to be an EGR valve desired/actual position mismatch code?? Maybe pull the EGR valve to see if it is all carboned up. May it just needs a cleaning. Also you repeated the thread from the wheel loader section. Please try not to duplicate threads.
