This long-form guide will break down everything you need to know: from the types of error codes, how to access them, a categorized list of common codes, diagnostic steps, and when to call a professional. Before diving into a list of codes, it is crucial to understand how Valtra systems communicate faults.
| Code | Description | Likely Cause | | :--- | :--- | :--- | | | Rear Lift Position Sensor Fault | Calibration lost (common after battery disconnect). Needs recalibration. | | MID 229 PID 28 | Hydraulic Oil Filter Clogged | Change filter immediately. Bypass valve may be open. | | SPN 122 FMI 2 | Rear Linkage Angle Sensor – Data Erratic | Broken sensor linkage arm or faulty potentiometer. | | AUX 1 Not Responding (generic) | Remote valve failure | Coil resistance low (shorted) or stuck spool. | Category 4: Electrical / CAN-bus These are frustrating but often intermittent. valtra error codes
| Code (MID/SID) | Description | Likely Cause | | :--- | :--- | :--- | | | Clutch 1 Speed Sensor | Sensor gap too wide, faulty sensor, or broken wiring. Tractor may jerk. | | MID 028 SID 27 | AutoTract (Cruise control) not available | Brake pedal switch stuck, clutch switch faulty, or speed signal lost. | | MID 138 PID 175 | Transmission Oil Temperature Too High | Overloading, low oil level, or clogged cooler. Reduce load. | | ERROR 05-12 (SmartTouch) | CVT Belt Slip Detected ( Very Serious ) | Low oil pressure, worn variator belt, or mechanical failure. Stop immediately. | Category 3: Hydraulics & Linkage Errors here affect the rear lift, front loader, and remote valves. This long-form guide will break down everything you
By keeping this guide handy, learning how to access the diagnostic menu on your specific model, and performing basic troubleshooting steps, you can save hundreds of hours of downtime and thousands in repair bills. Needs recalibration
For owners and operators of Valtra tractors—whether a classic A-series workhorse, a versatile N-series, or a high-horsepower S-series—the moment a warning light flashes on the dashboard or an error code scrambles across the display can be unsettling. Valtra, known for its Finnish engineering and high level of customization (the "Sisu" philosophy), builds robust machines. However, like all modern agricultural equipment, they rely on a complex network of sensors, ECUs (Electronic Control Units), and CAN-bus systems.
