1. 1

   Verify the 5V reference supply voltage at the torque sensor connector

2. 2

   Inspect the 3-pin electrical connector and wiring harness for corrosion, pushed pins, moisture ingress, chafing, or shorts to ground

3. 3

   Check system fuses for the transmission and chassis control circuits

4. 4

   Ensure the torque sensor is mounted securely and check the sensor gap

1. 1

   Power down the tractor

   Power down the tractor, engage the parking brake, and allow the drivetrain to cool.

2. 2

   Locate the torque sensor

   Locate the transmission/flywheel torque sensor on the drivetrain (typically located near the hydraulic pump drive gear or PTO torque sensor housing).

3. 3

   Disconnect the electrical connector

   Disconnect the 3-pin electrical connector from the sensor.

4. 4

   Remove the faulty sensor

   Remove the mounting hardware securing the torque sensor and extract the faulty unit.

5. 5

   Install the new sensor

   Install the new OEM torque sensor and tighten the mounting hardware to the manufacturer's specified torque.

6. 6

   Reconnect the electrical harness

   Reconnect the electrical harness, ensuring the weather seal clicks into place.

7. 7

   Clear the fault codes

   Clear the fault codes using a CNH Electronic Service Tool (EST) or equivalent diagnostic scanner.

8. 8

   Perform sensor calibration

   Perform a transmission/flywheel torque sensor calibration procedure. If the new sensor is not calibrated, the transmission controller will not recognize it and will throw a U80 code.
