Have a John Deere 50G excavator that ran fine two days ago. Went to start it up today and it won’t turn over. Displayed the generic E:1100 engine failure code, which upon further investigation turns out to be 00066-04 indicating low voltage for the exhaust gas recirculation side sensor. I don’t have the manual for the thing, so am hoping for some help locating the sensor and rectifying the code.
