SCO 001872.16 – Front Hitch Position Sensor, Voltage Too High

SCO 001872.16 (SCO 1872.16)

Code: 001872.16

Shortcode: 1872.16


This error code, SCO 001872.16, indicates that the voltage of the front hitch position sensor has risen above 4.7 volts. This excessive voltage can prevent the sensor from operating correctly.


When this fault is detected, the control software will have limited or no function of the front hitch.


  • Inspect Wiring for Shorts:
    • Check the wiring and connections to the front hitch position sensor for any signs of shorts or excessive voltage. Repair or replace any damaged wires.
  • Verify Power Supply:
    • Ensure that the power supply to the sensor is stable and within the required voltage range. Replace the power supply components if necessary.
  • Check Electrical Connections:
    • Inspect all electrical connections for corrosion, looseness, or damage. Clean and secure connections as needed.
  • Monitor Voltage:
    • Continuously monitor the voltage at the position sensor input to ensure it stays within the recommended range.


Preventive Maintenance:

  • Regular inspections of the electrical system can help identify and address potential voltage issues before they cause operational problems.
