Code P113C 2018 GMC Sierra Description
The P113C diagnostic trouble code (DTC) specifically refers to the Exhaust Gas Temperature Sensor 2 not being plausible. This code is typically found in vehicles equipped with a diesel engine, such as the 2018 GMC Sierra. The Exhaust Gas Temperature (EGT) sensor is responsible for monitoring the temperature of the exhaust gases leaving the diesel particulate filter (DPF). This information is crucial for the engine control module (ECM) to regulate fuel injection timing, exhaust gas recirculation (EGR), and DPF regeneration processes.
Common Causes of P113C 2018 GMC Sierra
- Faulty EGT sensor 2
- Wiring or connector issues
- Exhaust system leaks or damage
- ECM software glitches
- Exhaust gas recirculation (EGR) system malfunction
Symptoms of P113C 2018 GMC Sierra
- Reduced engine power or performance
- Increased fuel consumption
- Check Engine Light illuminated
- Failed emissions test
- DPF regeneration issues
How to Fix P113C 2018 GMC Sierra
- Diagnose the issue by using a scan tool to read the DTC and inspect the EGT sensor 2 and related components.
- Test the EGT sensor 2 using a multimeter to check for proper resistance values.
- Inspect the wiring harness and connectors for any damage or corrosion.
- Replace the EGT sensor 2 if it is faulty, and repair or replace any damaged wiring/connectors.
- Clear the DTC and perform a road test to ensure the issue has been resolved.
Cost to Fix P113C 2018 GMC Sierra
The cost of repairing the Exhaust Gas Temperature Sensor 2 not plausible issue can vary depending on the specific cause of the problem and the labor rates in your area. Typically, replacing the EGT sensor 2 and addressing any wiring issues can cost between $200 and $500, including parts and labor. Additional costs may apply if other components need to be replaced or if further diagnosis is required. It's recommended to get a few quotes from local auto repair shops to get a more accurate estimate for your specific vehicle.

Frequently Asked Questions about P113C 2018 GMC Sierra Code
1. What does the OBDII code P113C mean on a 2018 GMC Sierra?
P113C indicates that the vehicle's ECM has detected an issue with the Exhaust Gas Temperature (EGT) Sensor 2, where its readings are not plausible or consistent with expected values.
2. What are the symptoms of P113C on a 2018 GMC Sierra?
Common symptoms include a Check Engine Light, reduced engine performance, poor fuel efficiency, and, in some cases, the vehicle entering limp mode.
3. What causes the P113C code to appear?
The most common causes are a faulty EGT sensor, damaged wiring or connectors, excessive soot buildup around the sensor, or issues with the ECM misinterpreting sensor data.
4. Can driving with the P113C code cause further damage?
Yes, driving with this code can lead to increased emissions, potential damage to the exhaust system, and reduced performance if left unresolved.
5. How do I fix the P113C code on my GMC Sierra?
Repairs may include inspecting and replacing the EGT sensor, repairing any damaged wiring or connectors, cleaning soot buildup, or updating the ECM software if necessary.
6. Where is Exhaust Gas Temperature Sensor 2 located on a 2018 GMC Sierra?
This sensor is typically located downstream in the exhaust system, often near the diesel particulate filter (DPF) or catalytic converter.
7. How can I test the EGT sensor for P113C?
You can test the sensor with a multimeter to check for proper resistance or use a scan tool to monitor real-time temperature readings for inconsistencies.
8. Is the P113C code specific to diesel engines on the 2018 GMC Sierra?
Yes, this code is more commonly associated with diesel engines due to their use of multiple EGT sensors for emissions control.
9. Can a clogged DPF cause the P113C code?
Yes, a clogged DPF can cause abnormal exhaust temperatures, leading to implausible readings from the EGT sensor and triggering this code.
10. How much does it cost to repair the P113C code on a GMC Sierra?
Repair costs can vary but typically range from $100 to $400, depending on whether the sensor needs replacement or if wiring repairs are required.
