Code P1196 2014 GMC Sierra Description
The P1196 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a problem with the Exhaust Gas Temperature Sensor 3 (EGT Sensor 3) performance while the engine is running. This sensor is responsible for monitoring the exhaust gas temperature in the vehicle's exhaust system. The EGT Sensor 3 is typically located downstream of the diesel particulate filter (DPF) in diesel engines or after the catalytic converter in gasoline engines.
Common Causes of P1196 2014 GMC Sierra
- Faulty EGT Sensor 3.
- Wiring or connector issues related to the sensor.
- Exhaust system leaks or damage.
- ECM software or hardware problems.
- Exhaust gas temperature abnormalities due to engine issues.
Symptoms of P1196 2014 GMC Sierra
- Check engine light illuminated on the dashboard.
- Decreased fuel efficiency.
- Rough idling or engine misfires.
- Reduced engine performance or power.
- Increased emissions output.
How to Fix P1196 2014 GMC Sierra
- Begin by diagnosing the specific cause of the EGT Sensor 3 performance issue using a diagnostic scanner to retrieve the trouble codes and data related to the sensor.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion. Replace any damaged components as necessary.
- Check the exhaust system for leaks or damage that could affect the sensor's readings. Repair or replace any faulty components.
- Clear the DTCs from the ECM memory and perform a test drive to ensure that the issue has been resolved.
- If the problem persists, consult a professional mechanic for further diagnosis and potential ECM reprogramming or replacement.
Cost to Fix P1196 2014 GMC Sierra
The typical repair costs for addressing a P1196 code related to the Exhaust Gas Temperature Sensor 3 performance issue in a 2014 GMC Sierra can range from $200 to $500, including parts and labor. However, it's important to note that actual costs may vary depending on the specific diagnosis time, labor rates, and parts needed for the repair. Auto repair shops commonly charge between $80 and $150 per hour for labor, with rates potentially higher in metropolitan areas or at dealerships and lower at independent shops.
