The wiring bundle routing down to the rear hitch axle can rub against metal components over time. Damaged insulation, broken wires, or corrosion in the primary harness plugs disrupt data transmission. 4. Solenoid Valve Control Errors
The fuel demand increases dramatically under heavy load. A small restriction that allows enough fuel for idling or light work becomes a critical bottleneck when the engine needs maximum fuel flow. This is why intermittent L302 codes are so characteristic of partial blockages rather than complete pump failure. valtra error code l302 link
Visual Inspection: Inspect the rear lift arms for any mechanical obstructions. Look at the wiring leading to the position sensor for obvious breaks or fraying. The wiring bundle routing down to the rear
If you want, I can provide a step-by-step wiring test procedure (multimeter/ohmmeter values and how to measure CAN terminator) or a checklist specific to your Valtra model — tell me your model and year. Solenoid Valve Control Errors The fuel demand increases
Sometimes a simple power cycle (turn off, remove key, wait 2 minutes) resets the CAN bus.
