P1196 2017 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 3 Performance Engine Running
Quick Answer
The P1196 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates an issue with the Exhaust Gas Temperature (EGT) Sensor 3's performance while the engine is running. Common causes include Faulty EGT Sensor 3: The sensor itself may be malfunctioning or damaged, leading to inaccurate temperature readings, Wiring Issues: Corrosion, breaks, or shorts in the wiring connected to the EGT Sensor 3 can disrupt the signal transmission, ECM Malfunction: A problem with the engine control module can prevent it from properly interpreting the data from the EGT Sensor 3. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1196 2017 Chevrolet Silverado Description
The P1196 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates an issue with the Exhaust Gas Temperature (EGT) Sensor 3's performance while the engine is running. The EGT Sensor 3 is a crucial component that measures the temperature of exhaust gases leaving the engine. This information is essential for the engine control module (ECM) to adjust fuel delivery and optimize combustion efficiency. When the EGT Sensor 3 is not performing as expected, it can lead to various performance issues and potentially cause long-term damage to the vehicle.
Common Causes of P1196 2017 Chevrolet Silverado
- Faulty EGT Sensor 3: The sensor itself may be malfunctioning or damaged, leading to inaccurate temperature readings.
- Wiring Issues: Corrosion, breaks, or shorts in the wiring connected to the EGT Sensor 3 can disrupt the signal transmission.
- ECM Malfunction: A problem with the engine control module can prevent it from properly interpreting the data from the EGT Sensor 3.
- Exhaust System Leaks: Any leaks in the exhaust system can affect the sensor's readings and trigger the P1196 code.
- Exhaust Gas Recirculation (EGR) System Problems: Issues with the EGR system can impact exhaust gas flow and temperature readings.
Symptoms of P1196 2017 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P1196 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Performance: The engine may experience a decrease in power and overall performance due to incorrect fuel delivery.
- Increased Emissions: A faulty EGT Sensor 3 can lead to higher emissions output, potentially causing the vehicle to fail emissions tests.
- Poor Fuel Efficiency: Inaccurate temperature readings can result in poor fuel efficiency as the ECM struggles to adjust fuel delivery accordingly.
How to Fix P1196 2017 Chevrolet Silverado
- Diagnostic Scan: Use a diagnostic scan tool to retrieve the specific trouble code and confirm that the issue is related to the EGT Sensor 3.
- Inspect Sensor: Check the EGT Sensor 3 for any visible damage or signs of malfunction. Replace the sensor if necessary.
- Check Wiring: Inspect the wiring harness connected to the sensor for any damage or connectivity issues. Repair or replace damaged wiring.
- Clear Codes: After repairing or replacing the sensor and addressing any wiring issues, clear the DTCs from the ECM memory.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the engine performance has returned to normal.
Cost to Fix P1196 2017 Chevrolet Silverado
The cost of repairing a P1196 code on a 2017 Chevrolet Silverado can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing the EGT Sensor 3 can range from $100 to $300, including parts and labor. Additional costs may apply if there are wiring issues or other components that need attention. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on your vehicle's condition and location. Keep in mind that labor rates can vary between $80 and $150 per hour, so it's advisable to inquire about rates before proceeding with the repair.
