P2482 2016 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 5 Circuit High Voltage
Quick Answer
The P2482 code in a 2016 Chevrolet Silverado indicates a problem with the Exhaust Gas Temperature (EGT) Sensor 5 Circuit, specifically reporting a high voltage reading. Common causes include Faulty EGT Sensor: The most common cause of the P2482 code is a malfunctioning EGT sensor, which may be sending incorrect voltage readings to the ECM, Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can lead to high voltage readings and trigger the code, ECM Malfunction: A problem with the engine control module can also cause erroneous high voltage readings from the EGT sensor. 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 Chevrolet Silverado Description
The P2482 code in a 2016 Chevrolet Silverado indicates a problem with the Exhaust Gas Temperature (EGT) Sensor 5 Circuit, specifically reporting a high voltage reading. This sensor is responsible for monitoring the exhaust gas temperature and providing data to the engine control module (ECM) to optimize fuel efficiency and emissions. When the voltage detected by the sensor is higher than expected, it can lead to various issues with the vehicle's performance.
Common Causes of P2482 2016 Chevrolet Silverado
- Faulty EGT Sensor: The most common cause of the P2482 code is a malfunctioning EGT sensor, which may be sending incorrect voltage readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can lead to high voltage readings and trigger the code.
- ECM Malfunction: A problem with the engine control module can also cause erroneous high voltage readings from the EGT sensor.
- Exhaust System Leaks: Leaks in the exhaust system can affect the temperature readings of the EGT sensor, leading to the code being triggered.
Symptoms of P2482 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P2482 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Power: The engine may experience a loss of power or reduced acceleration due to incorrect fuel mixture adjustments.
- Poor Fuel Economy: A faulty EGT sensor can lead to decreased fuel efficiency as the engine may not be running at optimal settings.
- Increased Emissions: The vehicle may emit higher levels of pollutants due to incorrect combustion caused by the high voltage reading from the EGT sensor.
How to Fix P2482 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the P2482 code and perform a thorough inspection of the EGT sensor, wiring, and exhaust system for any visible damage or issues.
- Replace EGT Sensor: If the sensor is found to be faulty, replace it with a new OEM or high-quality aftermarket sensor to ensure accurate readings.
- Repair Wiring: Repair any damaged or corroded wiring connecting the EGT sensor to the ECM to ensure proper voltage readings.
- Clear Codes: After completing the repairs, clear the code from the ECM's memory using the diagnostic scanner to reset the Check Engine Light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the Check Engine Light does not reappear.
Cost to Fix P2482 2016 Chevrolet Silverado
The typical repair costs for addressing the P2482 code in a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. On average, replacing a faulty EGT sensor can cost between $150 and $300, including parts and labor. However, if additional repairs are needed for wiring or other components, the total cost may increase. It's important to note that diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. For a more accurate estimate, it's recommended to consult with local auto repair shops.

Frequently Asked Questions about P2482 2016 Chevrolet Silverado Code
1. What does code P2482 mean on a 2016 Chevrolet Silverado?
Code P2482 indicates a high voltage issue in the circuit of Exhaust Gas Temperature (EGT) Sensor 5, which monitors exhaust gas temperatures for emissions and engine performance.
2. What are the common symptoms of P2482 on a 2016 Chevrolet Silverado?
Common symptoms may include an illuminated check engine light, reduced engine performance, increased emissions, or the vehicle entering limp mode.
3. What causes the P2482 code to appear?
Possible causes include a faulty EGT sensor 5, damaged or corroded wiring/connectors in the sensor circuit, or a malfunctioning Engine Control Module (ECM).
4. Can you drive a 2016 Chevrolet Silverado with code P2482?
While the truck may still be drivable, continued use can lead to increased emissions, reduced fuel efficiency, and potential damage to the exhaust system over time.
5. How do you diagnose the P2482 code?
Diagnosis involves inspecting the EGT sensor 5 and its wiring for damage, checking for proper voltage and resistance, and performing a scan with an OBDII scanner to confirm the fault.
6. How can you fix the P2482 code on a 2016 Chevrolet Silverado?
Repairs typically involve replacing the faulty EGT sensor 5, repairing or replacing damaged wiring, and clearing the code with an OBDII scanner.
