C039E 2015 Chevrolet Silverado Code - Range Actuator Position Sensor Direction Signal Circuit
Quick Answer
The Transfer Case Control Module receives input from the range actuator position sensor and the transfer case range position sensor. Common causes include Faulty Transfer Case Motor (Transfer Case Two/Four Wheel Drive Actuator), Transfer Case Motor harness is open or shorted, Transfer Case Motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C039E 2015 Chevrolet Silverado Description
The range actuator position sensor receives an 8-volt reference signal from the Transfer Case Control Module. In return, the range actuator position sensor sends the Transfer Case Control Module a variable pulse width modulated signal indicating the position of the transfer case and a range actuator position direction signal. The range actuator position sensor, inside the A16 transfer case motor, also known as the transfer case range actuator, works in conjunction with the range position sensor to confirm the transfer case position. The range actuator position sensor is more sensitive than the transfer case range position sensor and is able to indicate to the Transfer Case Control Module the exact position of the transfer case between range changes. It is also able to show how much clutch activation is being commanded at any time.
The transfer case range position sensor, also known as the transfer case two/four-wheel drive actuator position sensor, receives a 5-volt reference signal from the Transfer Case Control Module and sends back a continuously variable pulse width modulated signal to the Transfer Case Control Module. This continuously variable signal indicates the position of the transfer case actuator.
The range actuator position sensor is more sensitive than the transfer case range position sensor but needs to reference the transfer case range position sensor value at ignition ON and mode changes. The transfer case range position sensor is an absolute sensor. The Transfer Case Control Module synchronizes the range actuator position sensor with the transfer case range position sensor at ignition ON and mode changes.
The range actuator position sensor is an integral part of the A16 Transfer Case Motor and cannot be replaced independently.
The transfer case range position sensor, also known as the gear position sensor, is an independently replaceable part.
What are the Possible Causes of the DTC C039E 2015 Chevrolet Silverado?
- Faulty Transfer Case Motor (Transfer Case Two/Four Wheel Drive Actuator)
- Transfer Case Motor harness is open or shorted
- Transfer Case Motor circuit poor electrical connection
- Faulty Transfer Case Control Module

Symptoms may include the "Service 4WD" light on the dashboard, inability to shift into or out of four-wheel drive modes, and unusual noises during transfer case operation.
3. What causes the C039E code to appear on a 2015 Chevrolet Silverado?
Common causes include a faulty range actuator position sensor, damaged wiring or connectors in the sensor circuit, corrosion, or a malfunctioning transfer case control module.
4. Can I drive my 2015 Chevrolet Silverado with the C039E code?
Driving may still be possible, but the four-wheel-drive system may not function correctly, which could affect handling and performance in certain conditions.
5. How do I diagnose the C039E code in a 2015 Chevrolet Silverado?
Start by inspecting the range actuator position sensor and its wiring for damage or corrosion. Use a scan tool to monitor sensor data and check for proper signal outputs.
6. How is the C039E code fixed on a 2015 Chevrolet Silverado?
Repairs may involve replacing the range actuator position sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the transfer case control module.
7. How much does it cost to repair the C039E code on a 2015 Chevrolet Silverado?
Repair costs can vary but typically range from $150 to $400, depending on whether the sensor, wiring, or control module needs replacement.
8. Can a bad transfer case control module cause code C039E on a 2015 Chevrolet Silverado?
Yes, a malfunctioning transfer case control module can cause this code by failing to communicate properly with the range actuator position sensor.
9. What tools are needed to troubleshoot the C039E code on a Chevrolet Silverado?
You will need an OBDII scan tool capable of reading transfer case codes, a multimeter for testing electrical circuits, and basic hand tools for inspection and repairs.
10. Is the C039E code common on 2015 Chevrolet Silverado trucks?
