Code P0882 2016 GMC Sierra Description
The P0882 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates that the Transmission Control Module (TCM) is detecting a low voltage condition in the supply voltage circuit. The TCM is responsible for controlling various functions related to the transmission, such as shifting gears, torque converter lockup, and overall transmission performance. When the TCM detects a low voltage situation, it can lead to erratic transmission behavior, poor shifting, and even transmission failure.
Common Causes of P0882 2016 GMC Sierra
- Faulty TCM power supply circuit
- Damaged wiring harness
- Blown fuse
- Malfunctioning relay
- Defective TCM
Symptoms of P0882 2016 GMC Sierra
- Harsh or delayed shifting
- Transmission slipping
- Limp mode activation
- Check Engine Light illuminated
- Loss of power or acceleration
How to Fix P0882 2016 GMC Sierra
- Begin by inspecting the wiring harness for any visible damage or corrosion. Repair or replace any damaged wires.
- Check the fuses related to the TCM power supply circuit and replace any blown fuses.
- Test the relay responsible for providing power to the TCM and replace if necessary.
- Use a multimeter to check the voltage output of the TCM power supply circuit to ensure it is within the specified range.
- If the issue persists, consider replacing the TCM itself after verifying all other components are functioning correctly.
Cost to Fix P0882 2016 GMC Sierra
The typical repair costs for addressing a P0882 code on a 2016 GMC Sierra can range from $200 to $600, depending on the specific cause of the issue and the cost of parts and labor.
