Code P1196 2014 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 2014 GMC Sierra Code

1. What does the P1196 code mean on a 2014 GMC Sierra?

The P1196 code indicates an issue with Exhaust Gas Temperature Sensor 3, specifically that it is not performing within the expected parameters when the engine is running.

2. What are the symptoms of a P1196 code?

Common symptoms include reduced engine performance, increased emissions, possible activation of limp mode, and an illuminated check engine light.

3. What causes the P1196 code to appear?

Possible causes include a faulty Exhaust Gas Temperature Sensor 3, damaged wiring or connectors, soot buildup on the sensor, or a malfunctioning engine control module (ECM).

4. Can I drive my 2014 GMC Sierra with a P1196 code?

While the vehicle may still be drivable, ignoring the code could lead to poor fuel efficiency, increased emissions, and potential damage to other exhaust system components.

5. How do I diagnose the P1196 code?

Use an OBDII scanner to confirm the code, inspect the Exhaust Gas Temperature Sensor 3 and its wiring for damage, and test the sensor's functionality with a multimeter.

6. How do I fix the P1196 code?

Repairs may include cleaning or replacing the Exhaust Gas Temperature Sensor 3, repairing damaged wiring or connectors, or, in rare cases, reprogramming or replacing the ECM.

7. How much does it cost to fix a P1196 code on a 2014 GMC Sierra?

The cost varies depending on the repair, but replacing the sensor typically costs $100-$300, including parts and labor.

8. Can a dirty Exhaust Gas Temperature Sensor cause the P1196 code?

Yes, soot buildup or contamination on the sensor can cause it to malfunction and trigger the P1196 code.

9. Does the P1196 code affect emissions?

Yes, a malfunctioning Exhaust Gas Temperature Sensor can lead to incorrect readings, resulting in increased emissions and potential failure of an emissions test.

10. Is there a way to prevent the P1196 code from occurring?

Regular maintenance, such as cleaning the exhaust system and ensuring proper sensor operation, can help prevent the P1196 code from triggering.
