Code P0882 2017 GMC Sierra Description
The P0882 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates an issue with the Transmission Control Module (TCM) Supply Voltage Circuit, specifically a low voltage condition. The TCM is a crucial component of the vehicle's transmission system, responsible for controlling various functions such as shifting, torque converter lockup, and more. The TCM requires a stable and adequate supply of voltage to operate effectively.
Common Causes of P0882 2017 GMC Sierra
- Faulty TCM power supply relay
- Corroded or loose electrical connections
- Defective TCM
- Battery or alternator issues affecting voltage supply
- Wiring harness damage or short circuits
Symptoms of P0882 2017 GMC Sierra
- Erratic shifting patterns
- Harsh shifts
- Delayed engagement
- Transmission slipping
- Vehicle going into limp mode
How to Fix P0882 2017 GMC Sierra
- Begin by conducting a thorough inspection of the TCM power supply relay, electrical connections, and wiring harness for any visible damage or corrosion.
- Test the TCM power supply relay using a multimeter to ensure it is functioning correctly.
- Check the battery and alternator to ensure they are providing the correct voltage to the TCM.
- If necessary, replace the TCM power supply relay, repair any damaged wiring, or replace the TCM itself.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0882 2017 GMC Sierra

2. What are the common symptoms of code P0882 on a 2017 GMC Sierra?
Symptoms may include a check engine light, transmission stuck in a single gear (limp mode), harsh or delayed shifting, or no communication with the TCM.
3. What causes the P0882 code on a GMC Sierra?
Common causes include a faulty TCM power supply relay, damaged wiring or connectors in the TCM circuit, a weak or failing battery, or a malfunctioning TCM.
4. Can a weak battery cause the P0882 code on a 2017 GMC Sierra?
Yes, a weak or failing battery can result in insufficient voltage reaching the TCM, triggering the P0882 code.
5. How do I diagnose the P0882 code on my GMC Sierra?
Start by checking the battery voltage, inspecting wiring and connectors for damage, testing the TCM power supply relay, and verifying proper voltage at the TCM.
6. Can I still drive my 2017 GMC Sierra with the P0882 code?
Driving with this code is not recommended, as the transmission may operate in limp mode, which can lead to further damage or unsafe driving conditions.
7. What repairs can fix the P0882 code on a GMC Sierra?
Repairs might include replacing a faulty TCM power relay, repairing damaged wiring or connectors, replacing the battery, or, in rare cases, replacing the TCM.
8. How much does it cost to fix the P0882 code on a GMC Sierra?
Repair costs vary but typically range from $100 for wiring repairs to $1,000 or more for a TCM replacement, depending on the exact issue.
9. Can a blown fuse cause the P0882 code on a 2017 GMC Sierra?
Yes, a blown fuse in the TCM power circuit can interrupt voltage supply and trigger the P0882 code.
10. Will clearing the P0882 code with a scanner fix the issue?
Clearing the code will turn off the check engine light temporarily, but the underlying problem must be resolved to prevent the code from returning.
