P113D 2014 GMC Sierra Code - Exhaust Gas Temperature Sensor 3 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 P113D 2014 GMC Sierra Code
1. What does the OBDII code P113D mean on a 2014 GMC Sierra?
P113D indicates an issue with Exhaust Gas Temperature Sensor 3, where the sensor's readings are deemed "not plausible" or inconsistent with expected values.
2. What are the symptoms of P113D on a 2014 GMC Sierra?
Symptoms may include the Check Engine Light turning on, reduced engine performance, poor fuel economy, or the vehicle entering limp mode.
3. What causes the P113D code to appear?
Common causes include a faulty exhaust gas temperature sensor, wiring or connector issues, exhaust leaks, or soot buildup on the sensor.
4. Can I drive my 2014 GMC Sierra with a P113D code?
While the vehicle may still be drivable, ignoring this code can lead to reduced performance, potential damage to the emissions system, and increased fuel consumption.
5. How do I fix the P113D code on my 2014 GMC Sierra?
Repairs may include replacing the faulty exhaust gas temperature sensor, repairing damaged wiring or connectors, or cleaning soot buildup in the exhaust system.
6. Where is Exhaust Gas Temperature Sensor 3 located on a 2014 GMC Sierra?
Sensor 3 is typically located downstream in the exhaust system, commonly near the diesel particulate filter (DPF) or catalytic converter.
7. How do I diagnose the P113D code?
Diagnosis involves inspecting the sensor and its wiring for damage or soot, checking for exhaust leaks, and using a scan tool to monitor sensor readings.
8. How much does it cost to fix the P113D code on a 2014 GMC Sierra?
Repair costs vary but typically range from $100 to $300 for parts and labor, depending on whether the sensor needs replacement or if wiring repairs are required.
9. Can a dirty exhaust system cause the P113D code?
Yes, soot buildup or restrictions in the exhaust system can interfere with the sensor's accuracy and trigger the P113D code.
10. Will replacing the exhaust gas temperature sensor clear the P113D code?
If the sensor is the root cause, replacing it will often resolve the issue. However, the code should be cleared with a scan tool after repairs to confirm it doesn’t reappear.
