New Holland 16113 – ATC: A/C Outlet Temp Sensor Circuit Fault

The fault code indicates a specific electrical failure related to the air conditioning system's outlet temperature sensor. The control module has detected that the sensor's circuit is either open (a break in the wiring) or has shorted to a power source, resulting in an abnormally high voltage reading. This prevents the climate control system from accurately measuring the temperature of the air being delivered to the cabin.

1. 1

   Visually inspect the wiring harness and connector associated with the air conditioning outlet temperature sensor for breaks, chafing, corrosion, or loose pins

2. 2

   Using a multimeter, verify that the sensor connector has the correct power supply and a solid ground connection as specified in the service manual

3. 3

   Disconnect the sensor and measure its internal resistance with a multimeter (an infinite resistance reading indicates an open circuit within the sensor, while zero indicates an internal short)

4. 4

   Perform a wiggle test by gently moving the wiring harness with the system on to see if the fault code changes status, which helps identify intermittent connections

1. 1

   Isolate the fault

   Follow the diagnostic checks to determine whether the fault lies with the sensor itself, the wiring, or the connector.

2. 2

   Repair wiring or connectors

   If a wiring issue is found, repair the damaged section of the harness using appropriate connectors and heat shrink tubing to ensure a weather-resistant repair. Replace any damaged connectors.

3. 3

   Replace the sensor

   If the sensor is determined to be faulty, replace it. The outlet temperature sensor is located within the HVAC housing, typically downstream of the evaporator and heater core. Access may require the removal of dash panels or covers.

4. 4

   Clear fault codes

   After the repair is complete, use a diagnostic tool to clear the fault code from the ATC module's memory.

5. 5

   Verify the repair

   Operate the air conditioning system and monitor the live data from the outlet temperature sensor to ensure it is providing a plausible temperature reading. Check that the A/C system functions correctly and that the fault code does not reappear.
