Understanding Valtra Error Codes: A Comprehensive Troubleshooting Guide
When a Valtra tractor experiences a technical issue, it communicates through a series of service codes displayed on the dashboard or SmartTouch screen. These codes are vital for diagnosing malfunctions in complex systems like the engine, transmission, and hydraulics. Understanding these codes can help you determine if a problem requires a simple reset or professional service from an official Valtra dealer. How to Read Valtra Service Codes
Valtra service codes often appear in a multi-part format (e.g., 000091-13-035) and scroll across the display in sections: First Part: Usually four zeros (e.g., 0000).
Second Part: Identifies the component (e.g., 0091 for the throttle).
Third Part: The Failure Mode Identifier (FMI), which describes the nature of the fault (e.g., 13 for calibration error). Fourth Part: A category identifier (e.g., 035).
To view active codes on older models, you can often enter a "Test Mode" or use the Agroline instrument panel to scroll through the fault memory. On modern SmartTouch displays, errors appear directly on the Tractor Health screen. Common Valtra Error Codes and Meanings
Valtra tractors use various prefixes (A, P, F, L) to categorize faults within specific control units. Engine and Sensor Faults (Sisu/AGCO Power)
Commonly referred to as EEM3 or EEM4 codes, these relate to the Sisu Diesel engine management system: valtra error codes
110/111: Coolant temperature sensor defect (Low or High signal). 121: Water detected in the fuel filter.
263-266: Fuel rail pressure issues (above or below normal range).
421-423: MPROP control faults, typically indicating an open or short circuit in the fuel high-pressure pump control. Transmission and Shuttle Faults
These codes often start with "P" (Proportional valve) or "L" and relate to the Powershift or DPS units:
P101-P105: Faults in the DPS proportional valves (P1, P2, P3). These often signal a short circuit or damaged wiring.
P107/P109: Forward or Reverse drive proportional valve current errors.
A311/A312: Gearbox oil temperature sensor reading is impossible (over 150°C or below -50°C). SPN: Identifies what system has the fault (e
L422: One shuttle direction has been engaged for over 3 seconds without full control activation. Hydraulic and Linkage Faults
The rear linkage system (Bosch TC1) uses its own set of "Flash Codes" or service codes:
Flash Code 17: Battery voltage is too high (over 19V), requiring an alternator check.
Flash Code 22: Position sensor signal is faulty or incorrectly adjusted.
Flash Code 31/32: RH or LH side draft sensor signal is too high or too low.
Flash Code 44: CAN bus time-out; the linkage control unit is not receiving data from the main tractor control unit. Immediate Troubleshooting Steps

Category 2: Transmission & AutoTract (CVT / Direct)
Valtra offers several transmissions: HiTech (shuttle), Versu (semi-powershift), and CVT (smooth shift). Errors here often trigger a "Transmission Limp Mode."
| Code (MID/SID) | Description | Likely Cause | | :--- | :--- | :--- | | MID 140 SID 37 | 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. |
Decoding the Codes: The SPN and FMI System
Modern Valtra tractors adhere to the J1939 industry standard for diagnostics. Therefore, most codes you encounter will not be simple "Error 01" messages, but rather a combination of SPN (Suspect Parameter Number) and FMI (Failure Mode Identifier).
- SPN: Identifies what system has the fault (e.g., SPN 100 is Engine Oil Pressure).
- FMI: Identifies what kind of fault occurred (e.g., FMI 0 means data valid but above normal operating range).
Example: If your display shows SPN 100 FMI 1, it translates to:
- SPN 100: Engine Oil Pressure.
- FMI 1: Data valid but below normal operating range.
- Diagnosis: Low Engine Oil Pressure.
Category 4: Electrical / CAN-bus
These are frustrating but often intermittent.
| Code | Description | Likely Cause | | :--- | :--- | :--- | | MID 256 SID 250 | 5-Volt Reference Low | A shorted sensor (like pressure sensor) is pulling down the 5V rail. | | CAN Bus Error (various) | Loss of communication between ECUs | Corroded connector, loose terminal, or damaged wiring harness (rodent damage). | | Battery Voltage Sens – Low | Alternator not charging | Worn alternator belt, faulty regulator, or bad battery cell. |
First Steps Before Calling a Dealer
Before booking a Valtra technician, try these:
- Restart the tractor – Wait 2 minutes with key off.
- Check fluids – Engine oil, AdBlue, hydraulic oil, coolant.
- Inspect wiring harnesses – Look for chafing near the cab pivot or front axle.
- Clean all connectors – Especially under the cab floor mats.
- Update software – Some codes are false triggers fixed by a free dealer update.
