New Holland 162-03: Coolant Temperature Sensor Failure - Short to B+

The coolant temperature sensor is experiencing a fault where it is shorted to B+ (battery positive voltage). This can cause incorrect temperature readings and may affect engine performance or cooling system operation.

1. 1

   The wiring and connections to the coolant temperature sensor

2. 2

   The integrity of the coolant temperature sensor itself

3. 3

   The presence of any damage or corrosion in the affected circuit

1. 1

   Inspect the wiring and connections to the coolant temperature sensor

   Check for any signs of damage, wear, or corrosion that could cause a short to B+.

2. 2

   Test the coolant temperature sensor

   Use a multimeter to verify the sensor's resistance and ensure it is functioning within the expected range.

3. 3

   Check for electrical interference or damage in the affected circuit

   Ensure that no other components or wiring in the circuit are causing the short to B+.
