    E51 is a faulty arm angle sensor . What are both your email addresses. ? I can you both tech manual for the machine .

  3. #3673moto2020-01-26 20:42

    Solid! [email protected] Thanks!!

    Manual emailed to you .

  5. #5Buckhorn2020-05-21 21:50

    Any chance I could get this info too. The dealer has been chasing after the throttle sensor.

  6. #6tool_king2020-05-21 22:08

    What is your email address ? If you have stuff to share back do so .

    Hey tool_king, you were spot on... the arm sensor wasn’t hooked up correctly. Problem solved!

  9. #9tool_king2020-05-23 20:16

    Manual emailed to you.

  10. #10Buckhorn2020-09-09 23:07

    Awesome info. I found the sensor to be faulty. I've been having trouble finding a replacement. Do you know if it could be bypassed? I believe it would involve using a resistor. And would disable the system.

  11. #11673moto2020-09-14 15:24

    Perhaps you could install a similar sensor from another manufacturer and cross your fingers?

  12. #12Buckhorn2020-09-14 17:49

    That makes sense. I would have to find one with similar resistance. Not sure if any john deere models have similar systems.

  13. #13673moto2020-09-14 20:34

    Deere or hitachi

  14. #14Loadall5262021-07-21 15:45

    Hi I have the same machine and have an -E- coming up in the display when I start - boom and dipper won’t operate - crowd and other functions are ok - anyone assist please ? Thanks

  15. #15Burton_792021-09-08 19:13

    I have a Zaxis 40 U imported from china. its ran great for years and the other day i started getting the same E51 fault code. Because its a china version no local Deer or Hitachi dealer can help me out. the only book i can find does not reference any E fault codes. is it possible it could be the same arm angle sensor and if so where is it, and how do i test it? everything operates fine, it just screams at me.

  16. #16673moto2021-09-08 22:29

    The sensor on mine was at the top of the arm where it meets the boom. .. the linkage had fallen off.

  17. #17Burton_792021-09-29 11:46

    673moto, thank you, you were spot on. my linkage had caught and spun. good to know the sensor works.

  18. #18crossers772022-03-22 05:15

    any chance of a manual . have same problem. useful information on here. thanks

    tool_king - would it be possible for you to send me the repair and parts manual for a John Deere 490e excavator? My email is [email protected]

  22. #22DAGP2022-08-20 13:25

    Could anybody help me with a E11 fault code on a Hitachi Ex135UR-5 ? Could it be associated with an E51 fault code, I know the arm to dipper sensor is not operating correctly

  23. #23Buckhorn2022-08-20 15:00

    E11 should be abnormal arm roll out function on a ex75ur. Could be similar to your machine

  24. #24Kevin_SC2022-09-09 07:26

    @ tool_king would it be possible to get all the 490e manuals you have emailed to [email protected] ? Thank you, Kevin

    Hi, Would it be possible to send this to me too please? Also where are you getting the error code from? I have the same screen as in Barteks post above but it doesn't seem to be working. It's a machine I purchased recently to use on a self build.

  43. #43Artem2025-10-27 20:42

    Have a good time. Please help, I'm restoring Hitachi EX75UR-3, there are error codes E11 E50 E51 I can't find the decryption If there are electric schemes, it would be great at all. Thank you very much

  44. #44Diesel Dave2025-10-29 08:52

    Your serial # prefix is 10V ? The electrical schematic is in the Operators manual # EM10VEN13 available at the Deere bookstore as a free download. https://www.johndeeretechinfo.com . I will try and find any fault code info.

  45. #45Artem2025-10-29 09:35

    Oh, thanks for the support. I've already solved the problem with this forum member. The thing was to cut the wire on a sensor that's attached to an arrow finger at its base. The key error was e50. In fact, there's still a lot of work to do, the excavator has been used for a long time without proper maintenance and even local fire survived, so far replaced all high pressure sleeves, absolutely everything. And now I'm restoring electricity, also repaired hydraulic pump, main

  46. #46rosajosh62025-12-22 11:43

    Can anyone tell me what a e50 code is. I have a zx30ur2. Or possibly send me a manual link thanks!
