P2482 2016 Chevrolet Silverado 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 Chevrolet Silverado 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 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.

7. How much does it cost to repair P2482 on a Chevrolet Silverado?

The repair cost varies depending on labor rates and parts, but replacing an EGT sensor usually costs between $150 and $300.

8. Can a dirty exhaust system cause the P2482 code?

Not directly, but excessive soot or buildup in the exhaust system can damage the EGT sensor over time, contributing to the issue.

9. Where is Exhaust Gas Temperature Sensor 5 located on a 2016 Chevrolet Silverado?

Sensor 5 is typically located in the exhaust system downstream of the catalytic converter, but the exact location may vary based on the engine configuration.

10. Will clearing the P2482 code fix the problem?

Clearing the code might temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
