Code P2047 2016 GMC Sierra Description
The P2047 diagnostic trouble code (DTC) for a 2016 GMC Sierra relates to the reductant injector control circuit. In vehicles equipped with Selective Catalytic Reduction (SCR) systems, the reductant injector is responsible for injecting a urea-based solution (AdBlue) into the exhaust stream to reduce harmful emissions. The reductant injector control circuit ensures that the injector operates correctly and at the appropriate times to optimize emissions control.
Common Causes of P2047 2016 GMC Sierra
- Faulty Reductant Injector: The reductant injector itself may be faulty, leading to issues with the control circuit.
- Wiring Issues: Damage to the wiring harness or connectors associated with the reductant injector control circuit can cause the P2047 code to be triggered.
- PCM Malfunction: A malfunctioning PCM may incorrectly interpret signals from the reductant injector control circuit, leading to the code being set.
- Software Update Needed: In some cases, a software update may be required to address issues with the reductant injector control circuit.
Symptoms of P2047 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P2047 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning reductant injector control circuit can lead to decreased fuel efficiency as the engine may not be operating at optimal levels.
- Engine Misfires: The engine may experience misfires or rough idling due to improper injection of the reductant solution.
- Failed Emissions Test: If the issue is not resolved, it can lead to increased emissions output, potentially causing the vehicle to fail emissions tests.
How to Fix P2047 2016 GMC Sierra
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific DTCs and pinpoint the exact cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness and connectors for any damage or corrosion that may be affecting the reductant injector control circuit.
- Test Reductant Injector: Test the reductant injector to ensure it is functioning properly and delivering the correct amount of urea solution.
- Replace Faulty Components: If the reductant injector or any associated components are found to be faulty, they should be replaced with new parts.
- Clear Codes and Test Drive: After completing the repairs, clear the DTCs from the PCM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2047 2016 GMC Sierra
The cost of repairing a P2047 code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. In general, the cost of parts for replacing a faulty reductant injector or related components can range from $200 to $500. Labor costs at an auto repair shop typically range from $80 to $150 per hour, and the total repair time may vary depending on the complexity of the issue. Therefore, the total cost of repairing a P2047 code could range from $300 to $800 or more, depending on the extent of the repairs needed. It is advisable to consult with a qualified mechanic or repair shop for a more accurate estimate based on the specific circumstances of the vehicle.
