The Kubota error codes are numerous and complex, while decoding them is complicated and frustrating. So this guide is designed to help you understand, diagnose, and, most importantly, reset Kubota error codes across the most popular models. Whether you’re running an SVL75-2 skid steer, a KX040-4 excavator, or an L-series tractor, and more.
Attention: Kubota Error Codes Are Not Universal
Before you search for a generic “Kubota error codes list,” you must understand this: codes are specific to the machine’s model, series, and engine type. An issue on a compact tractor may trigger a different code than the same issue on a large skid steer.
Your owner’s manual is always the most accurate source for your specific machine’s fault codes.
Kubota Error Codes Quick Lookup Guide
| Error Code | Problem / System | Common Causes | Recommended First Action | Primary Models Affected |
|---|---|---|---|---|
| P0087 | Low Fuel Pressure | Clogged filter, bad pump/sensor. | Replace the fuel filter. | Tractors, Skid Steers |
| P0563 | High System Voltage | Bad jump-start, bad alternator. | Test the battery and alternator. | All modern models |
| P3001 | High Soot Accumulation (DPF) | Excessive idling, regen failure. | Perform a manual DPF regeneration. | DPF-equipped models (SVL, KX/U, M-Series) |
| P3008 | Cam Position Sensor Fault | Bad sensor, wiring/connector issue. | Inspect the sensor and its wiring. | All modern electronically controlled engines |
| E:016 | Excavator Arm Solenoid Fault | Bad solenoid, wiring fault. | Inspect the arm control valve solenoid and harness. | Excavators (KX040, KX057) |
| Error 13 | Skid Steer Hydraulic Lock Fault | Bad solenoid, wiring, or safety sensor. | Check the lock solenoid and its wiring. | Skid Steers (SVL, SSV) |
| P0500 | Vehicle Speed Sensor Fault | Bad/dirty sensor, wiring damage. | Inspect the speed sensor and its wiring. | Utility Vehicles (RTV-XG850) |
Common Kubota Error Codes List
While a complete list is impossible, here are some of the most frequent error codes seen on Kubota equipment. We’ve included engine faults as well as machine-specific codes based on popular search queries for excavators, skid steers, and RTVs.
Engine & Fuel System Faults
P0087 – Fuel Rail / System Pressure – Too Low
This code indicates critically low fuel pressure, a common fault on everything from an MX5200 tractor to an SVL95 skid steer. It is often caused by a clogged fuel filter, a failing pump, or a faulty sensor. Your first action should be to replace the fuel filter, as it is the most frequent and affordable solution.
P0563 – System Voltage High
This code warns of dangerously high voltage in the electrical system, often triggered by an improper jump-start or a failing alternator. A faulty alternator can cause symptoms like flickering or overly bright lights and can damage other sensitive electronics. Your first step should be to have your battery and alternator professionally tested.
Emissions & DPF System Faults
P3001 – High Soot Accumulation
This common DPF code means the filter is full of soot, typically caused by excessive idling or an issue preventing automatic regeneration. You should perform a manual DPF regeneration cycle as instructed in your owner’s manual.
P3008 – Cam Position Sensor Circuit Fault
This code points to a fault in the camshaft position sensor circuit, which can affect engine timing. It is usually caused by a failed sensor, damaged wiring, or a corroded connector. Begin by carefully inspecting the sensor’s wiring and connector for any visible damage.
Hydraulic & Control System Faults
E:016 – Arm-In Solenoid Circuit Fault
This error is common on Kubota excavators like the KX040 and KX057 and indicates an electrical problem with the solenoid controlling the arm-in function. The cause is often a damaged wire, a poor connection, or a failed solenoid. Inspect the wiring harness leading to the control valve and test the solenoid itself.
Error 13 – Hydraulic Lock Solenoid Fault
Frequently seen on SVL and SSV series skid steers, this code means the safety hydraulic lock system is not engaging or disengaging correctly. This can be due to a faulty solenoid, a bad electrical connection, or a problem with the operator presence switch (lap bar/seat sensor). Check the solenoid and its wiring first.
Utility Vehicle Faults
P0500 – Vehicle Speed Sensor “A” Malfunction
This code is specific to utility vehicles like the RTV-XG850 Sidekick and points to a problem with the vehicle speed sensor. It can cause erratic speedometer behavior and may affect transmission shifting. The issue is often a dirty or failed sensor, or damaged wiring between the sensor and the ECU.
How to Reset Kubota Error Codes: A Step-by-Step Guide
Once you have identified and fixed the underlying problem, you can perform a reset to clear the code. Simply clearing the code without a repair will only cause it to reappear.
The following procedure is a user-verified method for many modern Kubota models. It refines the official instructions found in some manuals and clarifies confusing on-screen commands, as documented by owners on forums like TractorByNet.
A Real-World Example: Resetting an Error Code on a Kubota L3901
The Scenario: An owner of a Kubota tractor L3901 had a persistent P3001 (High Soot Accumulation) code. Even after performing a successful DPF regeneration, the code would not disappear.
The Proven Step-by-Step Reset Process:
- Enter Service Mode: Press and hold both DPF buttons simultaneously. While holding them, turn the ignition key to the “ON” position. The display should show the letter “A”.
- Select Clear Mode: Press the “Parked Regeneration” button to cycle through the menu options (“A”, “B”, “C”, “D”). Stop when the display shows “B” (Error Information Clear Mode).
- Initiate the Clear: Press and HOLD the “Parked Regeneration” button. You will hear a loud BEEP, and the display will show the word “PUSH”.
- Confirm the Action: This is the crucial step. When “PUSH” is displayed, press both DPF buttons simultaneously for 2-3 seconds. The display will then show “EXIT”.
- Finalize: Turn the ignition key OFF. When you power the tractor back on, the error code should be gone.
What to Do When the Reset Procedure Doesn’t Work
What if you follow the reset procedure perfectly, but the code remains? Another owner faced this exact issue with an “Error 20” on their tractor. After multiple failed attempts with the button sequence, they found a simple solution.
The remedy is to draw out the ECU main 5A fuse, give it a look-see, then put in a new one. When the fresh fuse is in place, the tractor can start properly, and the trouble code disappears. This happens because pulling the fuse is like making a “hard reset,” cutting away the electricity from the Engine Control Unit, and pushing it to wipe clean the fault memory still active.
This is a critical lesson: a persistent error code, especially after electrical work or a short, can often be caused by a blown fuse. Before spending hours on complex diagnostics, a quick check of your fuse box can save you significant time and frustration.
Frequently Asked Questions
1. Where can I find the error codes for my specific Kubota model, like a KX040-4 or L3901?
Your owner’s manual is the definitive source. Many users search for a “Kubota kx040-4 error codes pdf,” but the information is in the physical manual that came with your machine.
2. Is it okay to just reset the code and keep working?
Absolutely not. The error code is a warning. Ignoring it can lead to catastrophic and expensive engine damage. A reset is only for after a successful repair.
3. Are the error codes for a Kubota excavator different from a skid steer?
Yes. While some engine codes may overlap, each machine type has unique codes related to its specific systems (e.g., hydraulics on an excavator, drive systems on a skid steer).
