C0327 Chevrolet Code - Transfer Case Encoder Circuit Malfunction
Quick Answer
The transfer case encoder is a switch that converts a shaft position, representing a mode or range position, into electrical signals for use by the transfer case shift control module. Common causes include Faulty Transfer Case Encoder, Transfer Case Encoder harness is open or shorted, Transfer Case Encoder 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 C0327 Chevrolet Description
The transfer case shift control module supplies an 8-volt reference and a ground circuit for the encoder Hall effect sensors to function.
The transfer case shift control module supplies 5 volts on all the channels. As these channels are pulled to ground, the module can interpret the location of the transfer case shift position.
This DTC detects an open, short to ground, or a short to voltage in the encoder feed circuit, an open in the signal ground circuit, an open, short to ground, or short to voltage in the Encoder channel circuits.
What are the Possible Causes of the DTC C0327 Chevrolet?
- Faulty Transfer Case Encoder
- Transfer Case Encoder harness is open or shorted
- Transfer Case Encoder circuit poor electrical connection
How to Fix the DTC C0327 Chevrolet?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the C0327 Chevrolet code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about C0327 Chevrolet Code
1. What does the OBDII code C0327 mean on a Chevrolet?
C0327 indicates a malfunction in the transfer case encoder circuit, which is responsible for detecting the position of the transfer case shift motor.
2. What are common symptoms of code C0327 on a Chevrolet?
Symptoms may include the service 4WD light turning on, failure to engage or disengage 4WD modes, unusual noises from the transfer case, or the vehicle being stuck in one drive mode.
3. What causes the C0327 code to appear on a Chevrolet?
Common causes include a faulty transfer case encoder motor, damaged or corroded wiring in the encoder circuit, a bad transfer case control module (TCCM), or mechanical issues in the transfer case.
4. Can driving with code C0327 damage my vehicle?
While it may not immediately cause severe damage, ignoring the issue could lead to further wear on the transfer case or leave the vehicle stuck in an undesirable drive mode, potentially causing drivability issues.
5. How do I diagnose the C0327 code on a Chevrolet?
Start by checking the transfer case encoder motor and its wiring for damage or corrosion. Use a scan tool to monitor encoder motor data and test the transfer case control module for proper operation.
6. How is a transfer case encoder motor related to code C0327?
The encoder motor contains a sensor that detects the transfer case's position. If this sensor fails or the motor malfunctions, the circuit can't relay accurate position data, triggering the code.
7. What is the cost to fix code C0327 on a Chevrolet?
Repair costs can vary, but replacing a transfer case encoder motor typically costs between $300 and $600, including parts and labor. Additional wiring repairs or TCCM replacement may increase costs.
8. Can I fix the C0327 code myself?
If you're experienced with automotive repairs, you can attempt to replace the encoder motor or repair wiring issues. However, professional diagnosis is recommended to avoid misdiagnosing the issue.
9. Will clearing the code C0327 fix the problem?
Clearing the code may turn off the warning light temporarily, but the issue will likely reoccur unless the underlying problem with the encoder circuit is resolved.
10. How do I prevent the C0327 code from returning?
Regularly inspect and maintain the transfer case system, including its wiring and connections. Keeping the area free of moisture and debris can help prevent future issues.
