P2482 2016 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 2016 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 2016 GMC Sierra Code

1. What does the OBDII code P2482 mean for a 2016 GMC Sierra?

The P2482 code indicates a high voltage issue in the circuit of Exhaust Gas Temperature (EGT) Sensor 5, which monitors exhaust gas temperatures.

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

Symptoms may include the check engine light turning on, poor fuel efficiency, reduced engine performance, or the vehicle entering limp mode.

3. What causes the P2482 Exhaust Gas Temperature Sensor 5 Circuit High Voltage code?

Causes can include a faulty EGT sensor, damaged wiring or connectors, a short circuit, or corrosion in the sensor's electrical components.

4. Can I drive my 2016 GMC Sierra with the P2482 code?

Driving with this code is not recommended, as it may lead to engine damage or further issues with the emissions system.

5. How is the P2482 trouble code diagnosed?

Diagnosis involves using an OBDII scanner to confirm the code, inspecting the EGT sensor and its wiring, and testing the sensor's voltage with a multimeter.

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

Repairs may involve replacing the faulty EGT sensor, repairing damaged wiring, cleaning corroded connectors, or updating the vehicleâ€™s ECU software if necessary.

7. Where is Exhaust Gas Temperature Sensor 5 located on a 2016 GMC Sierra?

Sensor 5 is typically located in the exhaust system, downstream near the Diesel Particulate Filter (DPF) or catalytic converter.

8. How much does it cost to fix the P2482 code on a 2016 GMC Sierra?

Repair costs vary but typically range from $150 to $400, depending on whether the EGT sensor needs replacement or if wiring repairs are required.

9. Can a bad EGT sensor cause other issues in my GMC Sierra?

Yes, a faulty EGT sensor can affect emissions control, reduce fuel efficiency, and cause engine overheating or damage to the DPF system.

10. How can I prevent the P2482 code from reoccurring?

Regular maintenance, inspecting and cleaning exhaust system components, and addressing wiring issues promptly can help prevent this code from returning.
