Code P113D GMC Description
The P113D GMC code refers to the Exhaust Gas Temperature Sensor 3 Not Plausible. This code is indicating that the ECM (Engine Control Module) has detected a discrepancy in the exhaust gas temperature sensor 3 readings that are not within the expected range. The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. This information is crucial for the ECM to adjust fuel delivery and ensure optimal engine performance and emissions control.
Common Causes of P113D GMC
- Faulty Exhaust Gas Temperature Sensor 3.
- Wiring or connection issues with the sensor.
- Exhaust system leaks.
- Exhaust Gas Recirculation (EGR) system malfunction.
- ECM software or hardware issues.
Symptoms of P113D GMC
- Check Engine Light is illuminated on the dashboard.
- Decreased fuel efficiency.
- Rough idling or engine misfires.
- Failed emissions test.
- Reduced engine performance.
How to Fix P113D GMC
- Begin by visually inspecting the Exhaust Gas Temperature Sensor 3 and its wiring for any signs of damage or corrosion.
- Use a multimeter to test the sensor's resistance and voltage output.
- If the sensor is faulty, replace it with a new one following the manufacturer's instructions.
- Inspect the exhaust system for any leaks or damage that may be affecting sensor readings.
- Clear the diagnostic trouble codes from the ECM and perform a test drive to ensure the issue has been resolved.
Cost to Fix P113D GMC
The cost of repairing the Exhaust Gas Temperature Sensor 3 Not Plausible code can vary depending on the location, vehicle make and model, and the labor rates of the auto repair shop. Typically, the cost of a new sensor can range from $50 to $150, while the labor costs can range from $100 to $200. Overall, the total repair cost for this issue may be between $150 and $350. It is recommended to obtain quotes from local repair shops to get a more accurate estimate based on your specific circumstances.

Frequently Asked Questions about P113D GMC Code
1. What does the OBDII code P113D mean on a GMC vehicle?
P113D indicates that the Exhaust Gas Temperature (EGT) Sensor 3 is providing readings that are not plausible or outside the expected range.
2. What are the common symptoms of code P113D on a GMC?
Symptoms may include reduced engine performance, poor fuel efficiency, an illuminated check engine light, and potential issues with the exhaust after-treatment system.
3. What causes the P113D code to appear?
Common causes include a faulty EGT sensor, damaged wiring or connectors, exhaust system leaks, or a malfunctioning Engine Control Module (ECM).
4. Can I drive my GMC with the P113D code active?
Driving with the P113D code is not recommended, as it may lead to further damage to the exhaust system or emission components like the catalytic converter or diesel particulate filter (DPF).
5. How is the P113D code diagnosed?
A mechanic will typically use a scan tool to confirm the code, inspect the EGT sensor and wiring for damage, check for exhaust leaks, and test the sensor’s voltage and resistance.
6. How do you fix the P113D code on a GMC?
Repairs may include replacing the faulty EGT sensor, repairing damaged wiring or connectors, addressing exhaust leaks, or reprogramming/updating the ECM if necessary.
7. What is Exhaust Gas Temperature Sensor 3?
EGT Sensor 3 is a sensor in the exhaust system that monitors the temperature of exhaust gases to help regulate emissions and protect exhaust components.
8. How much does it cost to fix the P113D code on a GMC?
Repair costs can range from $150 to $400 depending on whether the sensor, wiring, or other exhaust components need repair or replacement.
9. Can a clogged diesel particulate filter (DPF) cause the P113D code?
Yes, a clogged DPF can cause abnormal exhaust temperatures, leading to implausible readings from the EGT sensor and triggering the P113D code.
10. Is it necessary to clear the code after repairs?
Yes, after making the necessary repairs, the code should be cleared using a scan tool to ensure the issue is resolved and the check engine light turns off.
