Code P1196 2016 GMC Sierra Description

The exhaust gas temperature sensors are variable resistors that measure the temperature of the exhaust gas. The exhaust temperature sensor 1 is the first exhaust temperature sensor on the exhaust system, the following exhaust temperature sensors are counted upward from the engine outlet to the exhaust system end. The Engine Control Module (ECM) supplies 5 V to the exhaust gas temperature signal circuit and supplies a ground to the low reference circuit. The exhaust gas temperature sensor temperature information is used by the ECM during the exhaust gas particulate filter cleaning process. The Diagnostic Trouble Code (DTC) will be set if the ECM detects that the difference between measured exhaust gas temperature and the estimated exhaust gas temperature is greater than a calibrated amount for greater than 1 s.

Frequently Asked Questions about P1196 2016 GMC Sierra Code

1. What does the OBDII code P1196 mean on a 2016 GMC Sierra?

P1196 indicates an issue with the performance of Exhaust Gas Temperature (EGT) Sensor 3 while the engine is running. This sensor monitors exhaust temperature to help manage emissions and protect engine components.

2. What are the common symptoms of code P1196 in a 2016 GMC Sierra?

Symptoms may include the check engine light turning on, reduced engine performance, increased emissions, poor fuel efficiency, or the vehicle entering limp mode.

3. What causes the P1196 code to appear on a 2016 GMC Sierra?

Common causes include a faulty Exhaust Gas Temperature Sensor 3, wiring or connector issues, excessive soot buildup, or a malfunctioning engine control module (ECM).

4. Can I drive my 2016 GMC Sierra with a P1196 code?

Driving with a P1196 code is not recommended, as it may lead to increased emissions, damage to the exhaust system, or reduced engine performance.

5. How can I diagnose the P1196 code on a 2016 GMC Sierra?

Start by visually inspecting the wiring and connectors for damage or corrosion. Use a scan tool to monitor EGT Sensor 3 readings and compare them to other sensors in the exhaust system.

6. How do I fix the P1196 code on a 2016 GMC Sierra?

Repairs may include replacing the faulty Exhaust Gas Temperature Sensor 3, repairing damaged wiring, cleaning soot-clogged components, or updating/reprogramming the ECM if necessary.

7. How much does it cost to fix the P1196 code on a 2016 GMC Sierra?

The cost can vary, but replacing the EGT sensor typically ranges from $100 to $300, including parts and labor. Additional repairs, such as wiring fixes or ECM updates, could increase the cost.

8. Can a dirty diesel particulate filter (DPF) trigger the P1196 code?

Yes, a clogged DPF can cause excessive heat buildup, which may lead to incorrect readings from Exhaust Gas Temperature Sensor 3 and trigger the code.

9. How do I prevent the P1196 code on my 2016 GMC Sierra?

Regular maintenance, including cleaning or replacing sensors, ensuring proper DPF operation, and addressing exhaust system issues promptly, can help prevent this code.

10. Will a P1196 code cause my 2016 GMC Sierra to fail an emissions test?

Yes, the P1196 code can cause your vehicle to fail an emissions test due to improper exhaust temperature management and increased emissions output.
