New Holland 19083: Power voltage 3 - coolant control valve and reverse mechanism valve (UB3), electric - UB3 circuit break - P20A0 vapor release valve (air recharger control valve) - circuit break

The fault code indicates a circuit break in the electric system related to the coolant control valve and reverse mechanism valve (UB3), as well as the P20A0 vapor release valve (air recharger control valve). This suggests a disruption in the electrical supply or connection to these components.

1. 1

   The electrical connections to the coolant control valve and reverse mechanism valve (UB3)

2. 2

   The electrical connections to the P20A0 vapor release valve (air recharger control valve)

3. 3

   The integrity of the circuit associated with the coolant control valve and reverse mechanism valve (UB3)

1. 1

   Inspect

   Inspect the electrical connections to the coolant control valve and reverse mechanism valve (UB3) for looseness, corrosion, or damage.

2. 2

   Inspect

   Inspect the electrical connections to the P20A0 vapor release valve (air recharger control valve) for looseness, corrosion, or damage.

3. 3

   Test

   Test the circuit associated with the coolant control valve and reverse mechanism valve (UB3) for continuity and proper voltage.
