P113B 2014 GMC Sierra Code - Exhaust Gas Temperature Sensor 1 Not Plausible
Quick Answer
The exhaust gas temperature sensors are variable resistors that measure the temperature of the exhaust gas at the inlet and outlet of the diesel oxidation catalyst as well as the inlet and outlet of the Diesel Particulate Filter (DPF). Common causes include Faulty Exhaust Gas Temperature Sensor, Exhaust Gas Temperature Sensor harness is open or shorted, Exhaust Gas Temperature Sensor circuit poor electrical connection. 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.

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.
