P113C 2016 GMC Sierra Code - Exhaust Gas Temperature Sensor 2 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 P113C 2016 GMC Sierra Code
1. What does the OBDII code P113C mean on a 2016 GMC Sierra?
P113C indicates that the Exhaust Gas Temperature (EGT) Sensor 2 is reporting values that are not plausible or outside the expected range, suggesting a potential sensor fault or related issue.
2. What are the symptoms of the P113C code in a 2016 GMC Sierra?
Common symptoms include an illuminated check engine light, reduced fuel efficiency, potential power loss, and, in some cases, the vehicle entering "limp mode."
3. What causes the P113C code to appear on a 2016 GMC Sierra?
Possible causes include a faulty Exhaust Gas Temperature Sensor 2, damaged wiring or connectors, soot buildup on the sensor, or issues with the vehicle's exhaust system or ECU.
4. Can I drive my 2016 GMC Sierra with the P113C code?
While the vehicle may still be drivable, it's not recommended since ignoring the issue could lead to reduced performance, increased emissions, and potential damage to the exhaust system or other components.
5. How is the P113C code diagnosed?
A mechanic will typically use a scan tool to confirm the code, inspect the EGT sensor and wiring for damage, and measure the sensor's resistance or voltage output to verify its operation.
6. How do you fix the P113C code on a 2016 GMC Sierra?
Repairs may include replacing the faulty EGT sensor, cleaning or repairing damaged wiring or connectors, clearing soot from the sensor, or reprogramming the ECU if necessary.
7. How much does it cost to fix the P113C code on a 2016 GMC Sierra?
Repair costs vary but typically range from $150 to $300 for sensor replacement, depending on labor rates and parts pricing.
8. Where is Exhaust Gas Temperature Sensor 2 located on a 2016 GMC Sierra?
Sensor 2 is usually located downstream in the exhaust system, often near the diesel particulate filter (DPF) or catalytic converter, depending on the exact configuration of the vehicle.
9. Can a dirty or clogged exhaust system cause the P113C code?
Yes, soot buildup or clogging in the exhaust system can affect the EGT sensor's readings and trigger this code.
10. Do I need to clear the P113C code manually after repairs?
After repairs, the code may need to be cleared using an OBDII scan tool, although the ECU may clear it automatically after several successful drive cycles.
