Hello What is hitachi code 11207-04? (my auto-idle wont rev down and downhill speed is too fast allso)
While I do not have information for your specific model, this is what I found for a similar product. 11207.04 - Pump 3 Control Pressure Sensor (B57) Signal Voltage is Low (below 0.1 V).
Thanks More trouble.. Mavhine stalls, if you pull lever before revs get high.. If revs are high - it can give power and wont stall. It has 9000h and type is zz225uslc-5b
