Code P113B 2014 GMC Sierra Description
The P113B diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates that the Exhaust Gas Temperature Sensor 1 is not providing plausible data to the engine control module (ECM). This sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. The ECM uses this information to adjust fuel delivery and optimize engine performance. When the sensor fails to provide accurate data, it can lead to a variety of issues that affect the vehicle's performance and emissions.
Common Causes of P113B 2014 GMC Sierra
- Faulty Exhaust Gas Temperature Sensor 1.
- Wiring or connector issues.
- ECM malfunction.
- Exhaust system leaks.
- Exhaust Gas Temperature Sensor 1 contaminated with soot or debris.
Symptoms of P113B 2014 GMC Sierra
- Check engine light illuminated on the dashboard.
- Reduced fuel efficiency.
- Engine running rough or misfiring.
- Increased emissions output.
- Loss of power or acceleration.
How to Fix P113B 2014 GMC Sierra
- Begin by diagnosing the issue using a scan tool to confirm the P113B code and pinpoint the faulty component.
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as necessary.
- Test the Exhaust Gas Temperature Sensor 1 for proper function and replace if found to be faulty.
- Clear the DTC from the ECM memory and test drive the vehicle to ensure the repair was successful.
- If the issue persists, further diagnostics may be required to identify any underlying problems with the ECM or exhaust system components.
Cost to Fix P113B 2014 GMC Sierra
The cost of repairing a P113B code on a 2014 GMC Sierra can vary depending on the specific cause of the issue.

Frequently Asked Questions about P113B 2014 GMC Sierra Code
1. What does the OBDII code P113B mean on a 2014 GMC Sierra?
P113B indicates an issue with the Exhaust Gas Temperature (EGT) Sensor 1, where its signal is deemed "not plausible" by the engine control module (ECM), suggesting an abnormal or inconsistent reading.
2. What are the common symptoms of code P113B on a 2014 GMC Sierra?
Symptoms may include reduced engine performance, poor fuel efficiency, illumination of the check engine light, and possible activation of limp mode.
3. What causes the P113B code to appear on a 2014 GMC Sierra?
The most common causes include a faulty EGT sensor, damaged wiring or connectors, soot buildup on the sensor, or an ECM software issue.
4. Can a dirty exhaust system cause code P113B?
Yes, excessive soot or carbon buildup in the exhaust system can lead to inaccurate readings from the EGT sensor, triggering the P113B code.
5. How do I diagnose the P113B code on my 2014 GMC Sierra?
Diagnosis typically involves inspecting the EGT sensor and its wiring for damage, testing the sensor’s resistance with a multimeter, and checking for any exhaust system blockages or leaks.
6. How do I fix the P113B code on a 2014 GMC Sierra?
Repairs may include replacing the faulty EGT sensor, cleaning or unclogging the exhaust system, repairing damaged wiring, or updating ECM software if needed.
7. Is it safe to drive with the P113B code on a 2014 GMC Sierra?
Driving with the P113B code may result in reduced engine performance and potential damage to the exhaust system or other components, so it’s best to address the issue promptly.
8. How much does it cost to fix the P113B code on a 2014 GMC Sierra?
Repair costs can vary, but replacing an EGT sensor typically ranges from $100 to $300, depending on labor rates and parts pricing.
9. Can a failing catalytic converter cause the P113B code?
While rare, a failing catalytic converter causing abnormal exhaust temperatures could contribute to triggering this code.
10. Can I clear the P113B code without fixing the issue?
Clearing the code without addressing the underlying problem may temporarily turn off the check engine light, but the code will likely return as the underlying issue persists.
