The L302 error code on your Valtra tractor's display screen indicates a problem with the tractor's hydraulic system, specifically with the "Load Control Valve" or "LCV" system. This system is responsible for controlling the flow of hydraulic fluid to various tractor functions, such as the loader, backhoe, or other hydraulic attachments.
Many Valtra models allow operators to recalibrate the hitch via the tractor’s dashboard terminal (such as the SmartTouch armrest or the standard A-pillar display). Enter the tractor’s service or setting menu. Navigate to the section. Select Hitch Calibration .
Use labor op code L302-HP (2.5 hours including diagnosis, SCV, and injector test).
The fuel circuit on modern Valtra tractors relies on a continuous balance of pressure. When the L302 fault displays on your dashboard panel, it points directly to one of the following mechanical or electrical failures:
Kills diesel bug (bacterial growth) that rapidly clogs filter elements. Before Sub-Zero Temperatures Prevents fuel gelling and wax crystallization in the lines. OEM Filter Changes Every 500 Hours (or sooner in dusty conditions)

: While reliable, the sensors can be sensitive to moisture and vibration over long periods of heavy use.
Turn the tractor ignition key to the "ON" position (do not start the engine).
If the filters are clean but the code persists, verify your supply flow.
Happy and productive farming!
