When the CAT 259D3 skid steer displays fault code 41-4, it typically indicates an issue within the hydraulic system. This fault code may be related to sensor malfunctions, hydraulic flow problems, or issues with other related components. Below are common troubleshooting steps and solutions for addressing this fault code.
Problem Description
Users have reported that their CAT 259D3 skid steer triggers fault code 41-4, and the hydraulic system fails to operate properly. Hydraulic functions may be limited, and the machine may not perform tasks like digging or lifting effectively. Typically, this issue is related to hydraulic flow, sensor problems, or faults in components like the hydraulic pump.
Common Causes and Solutions
Fault code 41-4 on the CAT 259D3 skid steer is typically related to the hydraulic system and can be caused by issues like low hydraulic oil, sensor failure, or problems with the hydraulic pump or valves. By systematically checking these components and addressing the underlying causes, most issues can be resolved. If the problem persists, it is recommended to contact Panswork’s professional repair service for a thorough inspection and repair to ensure the machine returns to normal operation.

Common Causes and Solutions
- Check Hydraulic Oil Pressure and Flow
Fault code 41-4 can be caused by insufficient hydraulic system pressure or flow. Check the hydraulic oil level and quality to ensure there is enough clean hydraulic fluid in the system. If the fluid is contaminated, replace it with fresh oil. Additionally, inspect the hydraulic pump to ensure it is operating correctly and providing the required flow of hydraulic fluid.
- Inspect Hydraulic Sensors
Hydraulic sensor failure can lead to incorrect pressure or flow readings, triggering fault code 41-4. Check the sensor connections for any loose wires or damage, ensuring the sensors are measuring the hydraulic system’s performance accurately. If a faulty sensor is identified, it should be replaced with a new one.
- Inspect Hydraulic Pump and Valves
A malfunctioning hydraulic pump or control valves can also cause low hydraulic pressure, leading to fault code 41-4. Inspect the hydraulic pump to verify that it is delivering sufficient fluid flow. Also, check the control valves to ensure they are operating correctly and allowing proper fluid distribution. If the pump or valves are found to be faulty, they should be repaired or replaced.
- Check the Electrical System and Control Module
Fault code 41-4 may also be triggered by electrical system issues. Check the electrical connections within the hydraulic system, particularly between the control module and sensors. Make sure the wiring is secure and there are no signs of wear or damage. If there are any electrical problems, damaged components should be replaced, or the wiring should be repaired.
- Perform a System Reset
After completing the above checks, if no obvious faults are found, attempt to perform a system reset. Disconnect the machine’s power, wait for a few moments, and then restart it to clear any temporary error codes. In some cases, a system reset can help restore normal operation.
