Code P10C8 2017 Chevrolet Silverado Description
The P10C8 diagnostic trouble code for a 2017 Chevrolet Silverado indicates that the Reductant Temperature Signal Message Counter is incorrect. This code is related to the vehicle's Selective Catalytic Reduction (SCR) system, which is responsible for reducing harmful emissions by injecting a urea-based solution (DEF - Diesel Exhaust Fluid) into the exhaust stream. The Reductant Temperature Signal Message Counter refers to the system's ability to accurately measure and monitor the temperature of the DEF fluid.
Common Causes of P10C8 2017 Chevrolet Silverado
- Faulty Reductant Temperature Sensor: A malfunctioning temperature sensor can send incorrect signals to the ECM, triggering this code.
- Wiring Issues: Corrosion, damaged wires, or poor connections in the wiring harness can disrupt the communication between the sensor and the ECM.
- Software Glitch: An issue with the ECM software or programming can also cause the message counter to be incorrect.
- DEF Contamination: Contaminated or poor-quality DEF fluid can affect the accuracy of the temperature readings in the SCR system.
Symptoms of P10C8 2017 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration due to the SCR system not functioning optimally.
- Poor Fuel Economy: A faulty SCR system can lead to increased fuel consumption as the engine may not be operating at peak efficiency.
- Failed Emissions Test: If the issue is not resolved, the vehicle may fail emissions tests due to increased emissions output.
How to Fix P10C8 2017 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and perform a thorough inspection of the SCR system components.
- Check Reductant Temperature Sensor: Test the functionality of the temperature sensor and replace it if necessary.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Reset ECM: Clear the trouble code from the ECM memory and reset the system to see if the issue reoccurs.
- Refill DEF Fluid: Ensure that the DEF fluid is of good quality and at the correct level in the tank to prevent further issues with the SCR system.
Cost to Fix P10C8 2017 Chevrolet Silverado
The typical repair costs for addressing a P10C8 code on a 2017 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, the cost of replacing a faulty Reductant Temperature Sensor can range from $100 to $200, including parts and labor. If wiring repairs are necessary, additional costs may apply. Overall, the total repair cost for this issue could range from $150 to $400. It's important to note that labor rates at auto repair shops can vary, so it's recommended to obtain quotes from multiple sources to get an accurate estimate.

Frequently Asked Questions about P10C8 2017 Chevrolet Silverado Code
1. What does the OBDII code P10C8 mean on a 2017 Chevrolet Silverado?
P10C8 indicates an issue with the reductant temperature sensor, specifically that the signal message counter is incorrect, which can affect the diesel exhaust fluid (DEF) system.
2. What are common symptoms of code P10C8 in a 2017 Silverado?
Symptoms may include a check engine light, DEF system warnings, potential reduction in engine power, and issues with emissions system performance.
3. What causes the P10C8 code to appear on a 2017 Chevrolet Silverado?
Common causes include a faulty reductant temperature sensor, wiring issues, poor electrical connections, or software-related communication errors in the DEF system.
4. Can a faulty reductant temperature sensor trigger the P10C8 code?
Yes, a malfunctioning reductant temperature sensor is one of the primary causes of this code.
5. How does the P10C8 code affect the DEF system in a 2017 Silverado?
The code can lead to incorrect DEF system operation, potentially causing emissions-related problems or reduced vehicle performance.
6. What steps should I take to diagnose the P10C8 code?
Start by inspecting the sensor and its wiring for damage or loose connections, check for related faults, and use a scan tool to monitor the reductant temperature sensor data.
7. Can I continue driving with the P10C8 code active?
While driving may still be possible, prolonged operation with this code can lead to emissions non-compliance, potential DEF system failure, or reduced engine power.
8. How is the P10C8 code typically resolved?
Repairs often involve replacing the reductant temperature sensor, repairing damaged wiring, or updating the vehicle’s software if necessary.
