E14 fault on komatsu PC80MR

Dave87 · 2025-07-01 15:24

I’ve got a 2010 Komatsu PC80MR throwing an E14 error code. From what I understand, it means “feedback system abnormal”—but I’m not getting anywhere with basic checks. I’ve tried: Checking throttle cable movement and actuator Verifying battery voltage and grounds Inspecting plugs/connectors under the seat and near the engine Still can’t clear the fault. Has anyone dealt with this before? Bonus points if you know how to clear/reset the error without dealer software—or if you can confirm what sensor triggers E14. Thanks in advance!
