P2482 2017 GMC Sierra Code - Exhaust Gas Temperature Sensor 5 Circuit High Voltage

Quick Answer

The Exhaust Gas Temperature sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) 5, Exhaust Gas Temperature Sensor 5 harness is open or shorted, Exhaust Gas Temperature Sensor 5 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2482 2017 GMC Sierra Description

The Exhaust Gas Temperature sensors (EGTS) are variable resistors that measure the temperature of the exhaust gas. Exhaust temperature sensor 1 is the first exhaust temperature sensor in the exhaust system, the following exhaust temperature sensors are counted upward from the engine outlet to the exhaust system end. The Engine Control Module (ECM) supplies 5 V to the exhaust gas temperature signal circuit and supplies a ground to the low reference circuit. The exhaust gas temperature sensor temperature information is used by the ECM during the exhaust gas particulate filter cleaning process. The Diagnostic Trouble Code (DTC) will ve set when the ECM detects that the exhaust gas temperature sensor is greater than 900 Ω for greater than 2 s.

Frequently Asked Questions about P2482 2017 GMC Sierra Code

1. What does the OBDII code P2482 mean on a 2017 GMC Sierra?

P2482 indicates a high voltage issue in the Exhaust Gas Temperature (EGT) Sensor 5 Circuit, which monitors exhaust temperatures to ensure proper emissions control.

2. What are the common symptoms of code P2482 in a 2017 GMC Sierra?

Symptoms may include the Check Engine Light turning on, poor engine performance, increased emissions, or the engine going into limp mode.

3. What causes the P2482 code to appear in a 2017 GMC Sierra?

Common causes include a faulty EGT sensor, damaged wiring or connectors, short circuits, or a malfunctioning Engine Control Module (ECM).

4. Can I drive my 2017 GMC Sierra with a P2482 code?

Driving with this code is not recommended as it may lead to increased emissions, reduced fuel efficiency, or damage to the exhaust system.

5. How do I diagnose the P2482 code on a 2017 GMC Sierra?

Use an OBDII scanner to confirm the code, inspect the wiring and connectors for damage, check the EGT sensor for faults, and test the circuit voltage for abnormalities.

6. How do I fix the P2482 code on my 2017 GMC Sierra?

Repairs may involve replacing the faulty EGT sensor, repairing or replacing damaged wiring, or reprogramming/updating the ECM if necessary.

7. What is the function of Exhaust Gas Temperature Sensor 5 on a 2017 GMC Sierra?

This sensor monitors and provides data on the exhaust gas temperature to help regulate emissions and protect exhaust system components like the catalytic converter.

8. How much does it cost to repair a P2482 code on a 2017 GMC Sierra?

Repair costs vary but typically range from $150 to $300, depending on whether the sensor, wiring, or other components need replacement.

9. Can a faulty EGT Sensor 5 cause damage to my 2017 GMC Sierra?

Yes, a faulty sensor can lead to improper exhaust system operation, increased emissions, and potential damage to components like the catalytic converter or turbocharger.

10. How can I prevent the P2482 code from returning on my 2017 GMC Sierra?
