Valtra error codes are numeric/alphanumeric fault identifiers generated by the tractor’s electronic control units (engine ECU, transmission ECU, hydraulic/ISOBUS controllers). Each code points to a specific sensor, actuator, or subsystem abnormality and helps diagnose faults faster. The Ultimate Guide to Valtra Error Codes: How

| Fault Code (Older System) | System/Component | Meaning / Typical Cause | Fault Level | | :--- | :--- | :--- | :--- | | | DPS Proportional Valve | The proportional valve P1 draws a current exceeding or falling below specified limits. Likely a short circuit or wiring damage. | 3 | | P103 | DPS Proportional Valve | The proportional valve P2 draws a current exceeding or falling below specified limits. Likely a short circuit or wiring damage. | 3 | | A311 | Gearbox Temperature | The gearbox oil temperature sensor (B14) signal is impossible, reading over +150°C. Likely a faulty sensor or wiring. | 3 | | A312 | Gearbox Temperature | The gearbox oil temperature sensor (B14) signal is impossible, reading under -50°C. Likely a faulty sensor or wiring. | 3 | | A313 | Accelerator Pedal Position | The signal from the accelerator pedal position sensor (B15) is below 1V or above 7V. Sensor may be incorrectly installed or the wiring damaged. | 3 | | d225 | Clutch Pedal | This code appears if the clutch pedal position is below 2% and the pedal limit switch (S9) has not yet switched on. This can point to a calibration issue. | N/A | Can’t copy the link right now

Codes often use a letter prefix followed by numbers to categorize the fault: A-Prefix (Tractor Control Unit):

Knowing the prefix directs your troubleshooting to the right area—there's no use checking the hydraulics when the issue is in the transmission.
