Code P007C 2016 Chevrolet Silverado Description
The P007C diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado refers to the Charge Air Cooler Temperature Sensor 1 Circuit Low Voltage. This code indicates that the voltage signal from the charge air cooler temperature sensor is lower than the expected range. The charge air cooler, also known as an intercooler, is responsible for cooling the air compressed by the turbocharger before it enters the engine. The temperature sensor monitors the temperature of the air in the charge air cooler to ensure optimal performance and efficiency.
Common Causes of P007C 2016 Chevrolet Silverado
- Faulty Temperature Sensor: The most common cause of the P007C code is a malfunctioning charge air cooler temperature sensor, which may be damaged or have a wiring issue.
- Wiring Issues: Corroded, damaged, or loose wiring connections related to the temperature sensor circuit can trigger the low voltage signal.
- ECM Malfunction: A malfunctioning engine control module (ECM) can also cause the sensor to read low voltage inaccurately.
- Intercooler Blockage: Blockages or restrictions in the charge air cooler can affect the sensor's readings and trigger the P007C code.
- Turbocharger Issues: Problems with the turbocharger, such as leaks or malfunctions, can impact the charge air cooler temperature sensor's performance.
Symptoms of P007C 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P007C code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Power: The engine may experience a decrease in power output, resulting in sluggish acceleration and overall performance.
- Poor Fuel Efficiency: A malfunctioning charge air cooler temperature sensor can lead to decreased fuel efficiency, causing the vehicle to consume more fuel than usual.
- Rough Idling: The engine may idle roughly or inconsistently due to incorrect temperature readings affecting fuel delivery and combustion.
How to Fix P007C 2016 Chevrolet Silverado
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the trouble codes and confirm the presence of the P007C code.
- Inspect Wiring: Check the wiring harness and connectors associated with the charge air cooler temperature sensor for any damage, corrosion, or loose connections.
- Test Temperature Sensor: Test the charge air cooler temperature sensor using a multimeter to ensure it is functioning correctly and providing accurate readings.
- Clear Codes: After addressing any issues with the sensor or wiring, clear the trouble codes from the ECM memory using the diagnostic scan tool.
- Test Drive: Take the vehicle for a test drive to ensure the check engine light does not reappear and that the engine performance has returned to normal.
Cost to Fix P007C 2016 Chevrolet Silverado
The typical repair costs for addressing the P007C code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, the cost of replacing a charge air cooler temperature sensor ranges from $100 to $200, including parts and labor. However, if additional components such as wiring harnesses or the ECM need to be replaced, the total repair cost may increase.

Frequently Asked Questions about P007C 2016 Chevrolet Silverado Code
1. What does the OBDII code P007C mean on a 2016 Chevrolet Silverado?
P007C indicates "Charge Air Cooler Temperature Sensor 1 Circuit Low Voltage," meaning the sensor is reporting a voltage level below the expected range to the engine control module (ECM).
2. What are common symptoms of P007C in a 2016 Chevrolet Silverado?
Common symptoms include poor engine performance, reduced fuel efficiency, illuminated check engine light, and potential engine overheating during heavy use.
3. What causes the P007C code to appear?
This code is often caused by a faulty charge air cooler temperature sensor, damaged wiring or connectors, or issues within the ECM.
4. Can I drive my 2016 Chevrolet Silverado with a P007C code?
While the truck may still run, driving with this code can lead to poor performance and potential engine damage if the issue is not addressed.
5. How do I diagnose the P007C code on my Silverado?
Start by inspecting the charge air cooler temperature sensor, checking for damaged wiring, loose connections, or corrosion. Use a multimeter to verify sensor voltage and resistance.
6. How do I fix the P007C code on a 2016 Chevrolet Silverado?
Repairs may include replacing the charge air cooler temperature sensor, repairing damaged wiring or connectors, or updating the ECM software if necessary.
7. Where is the charge air cooler temperature sensor located on a 2016 Chevrolet Silverado?
The sensor is typically located in the intake air system, near the intercooler or intake manifold. Refer to the vehicle’s service manual for the exact location.
8. How much does it cost to repair a P007C code on a Silverado?
Repair costs can vary but typically range from $100 to $300, depending on whether the sensor needs replacing or if wiring repairs are required.
9. Can a dirty intercooler cause the P007C code?
While unlikely, a clogged or dirty intercooler may affect airflow and indirectly contribute to temperature sensor issues. It’s worth inspecting during troubleshooting.
10. Will resetting the check engine light fix the P007C code?
Simply resetting the light won’t fix the underlying issue. The problem with the charge air cooler temperature sensor or its circuit must be resolved to prevent the code from returning.
