Code P113D 2017 GMC Sierra Description
The P113D diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the Exhaust Gas Temperature (EGT) Sensor 3 not providing plausible data to the engine control module (ECM). This sensor is responsible for monitoring the exhaust gas temperature in the exhaust system. When the ECM receives implausible data from the EGT Sensor 3, it can lead to issues with the vehicle's performance and emissions.
Common Causes of P113D 2017 GMC Sierra
- Faulty EGT Sensor 3
- Wiring or connector issues
- Exhaust system leaks
- ECM software issues
- Exhaust system malfunctions
Symptoms of P113D 2017 GMC Sierra
- Decreased fuel efficiency
- Reduced engine performance
- Illumination of the check engine light
- Rough idling or misfiring
- Increased emissions
How to Fix P113D 2017 GMC Sierra
- Begin by diagnosing the EGT Sensor 3 using a scan tool to confirm the fault.
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as necessary.
- Test the EGT Sensor 3 for proper operation and replace if found to be faulty.
- Clear the DTC from the ECM memory and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the exhaust system or ECM.
Cost to Fix P113D 2017 GMC Sierra
The typical repair costs for addressing the P113D code on a 2017 GMC Sierra can vary depending on the specific cause of the issue. In general, replacing a faulty EGT Sensor 3 and addressing any wiring or connector issues can range from $200 to $500, including parts and labor. However, it is important to note that diagnosis time and labor rates at auto repair shops can vary significantly, so it is advisable to check with local shops for a more accurate estimate. Additionally, rates may be higher at dealerships or in metropolitan areas, while independent shops may offer more affordable prices.
