1. 1

   Verify Actual Temperature: Use an external infrared thermometer or diagnostic tool to check the actual temperature of the hydraulic oil to see if it matches the warning.

2. 2

   Check Hydraulic Oil Level: Ensure the hydraulic oil tank is not empty or low (which would trigger sensor B084 / codes 0A.1.D8 or 0A.1.D9).

3. 3

   Check for Restrictions: Verify that the hydraulic oil filter is not clogged (monitored by contamination switch S119 / code 0A.1.DD).

4. 4

   Inspect Wiring: Check the wiring harness and the separation point connector (X162) at the B013 sensor for corrosion, damage, or a loose connection.

1. 1

   Safely park the tractor, turn off the engine, and allow the hydraulic system to cool completely.

   This avoids burn hazards.

2. 2

   Open the tractor bonnet.

3. 3

   Remove the right-side cover panel/metal panel.

   This provides access to the right side of the engine.

4. 4

   Locate the B013 Hydraulic Oil Temperature Sensor.

   It is mounted on the right side of the engine, specifically on the suction line leading to the auxiliary/steering pump.

5. 5

   Disconnect the electrical connector (Separation point X162) from the sensor.

6. 6

   Unthread and remove the faulty B013 sensor.

   Have a rag or catch pan ready to catch any residual hydraulic fluid that may weep from the port.

7. 7

   Install the new OEM temperature sensor and tighten to factory specifications.

8. 8

   Reconnect the X162 electrical connector.

9. 9

   Reinstall the right-side cover panel and close the bonnet.

10. 10

    Start the tractor and monitor the instrument panel.

    Ensure the 0A.1.DA warning does not return.
