Code P113C 2017 GMC Sierra Description

The P113C diagnostic trouble code (DTC) specifically pertains to the Exhaust Gas Temperature (EGT) Sensor 2 in a 2017 GMC Sierra. This code indicates that the EGT Sensor 2 is not providing plausible or accurate data to the engine control module (ECM). The EGT Sensor measures the temperature of the exhaust gases exiting the engine, providing valuable data for the ECM to optimize fuel delivery and emissions control.

Frequently Asked Questions about P113C 2017 GMC Sierra Code

1. What does the OBDII code P113C mean on a 2017 GMC Sierra?

P113C indicates that the Exhaust Gas Temperature (EGT) Sensor 2 is reporting values that the engine control module (ECM) deems implausible or inconsistent with expected readings.

2. What are the symptoms of code P113C on a 2017 GMC Sierra?

Common symptoms include a check engine light, reduced fuel efficiency, possible limp mode activation, and abnormal exhaust temperatures.

3. What causes the P113C code to appear?

The code can be triggered by a faulty EGT sensor, wiring issues (such as corrosion or short circuits), a malfunctioning ECM, or exhaust system damage affecting sensor accuracy.

4. Can I drive my 2017 GMC Sierra with the P113C code?

While the truck may still be drivable, ignoring the code can lead to reduced performance, higher emissions, and potential damage to exhaust components like the catalytic converter.

5. How do you diagnose the P113C code on a 2017 GMC Sierra?

Diagnosis typically involves scanning the ECM for related codes, inspecting the wiring and connectors of EGT Sensor 2, and testing the sensor’s resistance and voltage readings.

6. How do you fix the P113C code on a 2017 GMC Sierra?

Common fixes include replacing the faulty EGT sensor, repairing damaged wiring or connectors, and clearing the code using an OBDII scanner after repairs.

7. How much does it cost to repair the P113C code on a 2017 GMC Sierra?

The cost can vary but typically ranges from $100 to $300, including parts and labor, depending on whether the issue is with the sensor or the wiring.

8. Can a dirty exhaust system cause the P113C code?

While rare, excessive soot buildup in the exhaust system can potentially affect sensor readings, leading to implausible data being reported.

9. Is the P113C code related to emissions?

Yes, the EGT sensor plays a role in monitoring exhaust temperatures, which is crucial for maintaining proper emissions levels.

10. Can resetting the ECM clear the P113C code permanently?

Resetting the ECM may temporarily clear the code, but if the underlying issue isn’t resolved, the code will likely return.
