Direct answer
Do not order a speed sensor from “0101” alone. First establish the complete screen message, the machine identity and the controller or engine system reporting it. This guide does not assign a universal meaning or a test resistance to that code.
Scope and safety
This is a symptom-recording and service-handoff guide, not a procedure for testing or adjusting the machine. Follow the exact machine manual and displayed safety instructions. Keep clear of moving equipment and suspected pressurized leaks. Shutdown alone may not remove stored pressure; hydraulic work and attachment support require the correct procedure and qualified personnel.
Capture the original message
Photograph the code exactly as displayed, including prefixes, accompanying text and warning symbols. Preserve other active messages and the service history before clearing anything. Record whether the complaint is no-start, intermittent stopping, reduced power or a display-only warning.
Match the manual to the machine
Send the complete SH200-6 identification and engine plate information to the service provider. Ask for the code definition from documentation matching the installed control system. An informal “A6” description should not replace the manufacturer’s identification.
Require evidence before a sensor order
A technician should establish the sensor type, circuit and specified test method before measuring or replacing it. Generic resistance and air-gap values are not included here. Request the diagnosed component number and any applicable supersession before quotation.
Service handoff record
| Record | Information to supply |
|---|---|
| Identification | Full machine model and serial; engine or attachment identity where relevant. |
| Complaint | The affected function, direction, timing and original screen message. |
| History | Recent service, changed parts and existing test reports; mark missing information as unknown. |
| Diagnosis | Technician’s confirmed component, applicable manual reference and repair scope. |
Frequently asked questions
Is 0101 definitely a speed-sensor fault?
This page does not verify that mapping for your installed system. Use the matching manufacturer documentation and the full message.
What if the code disappears after restart?
Record that behavior and retain the original evidence. An intermittent complaint still needs its conditions documented.
Sources and scope of evidence
- Sumitomo service and support — manufacturer documentation or support access; obtain the reference for your exact machine.
- Caterpillar hydraulic hose inspection and pressure safety — general hydraulic inspection and stored-pressure safety.
These public sources provide documentation/support routes and general safety context. They do not verify a model-specific fault-code definition, pressure setting or repair case. This guide therefore supplies no such specifications. Source links checked 14 September 2026.

Parts identification after diagnosis
Danch Machinery supplies genuine parts. Send the confirmed part number, machine serial number and clear identification photographs for an availability and fitment inquiry. A symptom description does not establish fitment or current stock.
