Valtra F321: Engine RPM Lower Than Shuttle Sensor Indication When One Solenoid Is Active

The engine rpm is lower than what the shuttle sensors indicate, and this occurs when one solenoid is active. This suggests a discrepancy between the engine speed and the shuttle sensor readings under specific solenoid conditions.

1. 1

   The solenoid that is active during the fault

2. 2

   The shuttle sensors (B12/B13)

3. 3

   The connection or operation of the affected circuit

1. 1

   Inspect the solenoid that is active during the fault

   Check for any signs of damage, wear, or improper operation.

2. 2

   Test the shuttle sensors (B12/B13)

   Verify that the sensors are functioning correctly and providing accurate readings.

3. 3

   Check the affected circuit

   Ensure that there are no issues with wiring, connections, or power supply to the solenoid and sensors.
