When cleaning the cab or chassis with compressed air or a pressure washer, avoid directly blasting electronic control units (ECUs) and sensor plugs.
A transmission code might appear during heavy draft work if the transmission fluid overheats or if a speed sensor on the output shaft loses its signal, causing the tractor to drop into a neutral safety state. 3. Hydraulic and Linkage Errors
Low battery voltage, corroded ground wires, or a broken wire in the harness. valtra error codes
A surprising number of error codes are simply secondary reactions to low fluid levels or blocked filters. Check engine oil, transmission fluid, and coolant levels.
| 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 | When cleaning the cab or chassis with compressed
Isolate the battery using the main isolator switch (if equipped).
