P2482 2018 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 2018 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 2018 Chevrolet Silverado Code

What does the OBDII code P2482 on a 2018 Chevrolet Silverado indicate?

The P2482 code in a 2018 Chevrolet Silverado indicates that the vehicle's Engine Control Module (ECM) has detected a high voltage condition in the circuit of the exhaust gas temperature sensor for sensor 5.

What are the common symptoms of the P2482 code in a 2018 Chevrolet Silverado?

Symptoms of code P2482 may include a check engine light, reduced engine performance, increased fuel consumption, and in some cases, an audible knocking sound from the engine due to abnormal combustion temperatures.

What causes the P2482 code in a 2018 Chevrolet Silverado?

The P2482 code can be triggered by several issues, including a faulty exhaust gas temperature sensor, wiring problems like shorts or opens in the sensor circuit, or problems with the ECM itself.

How can I diagnose the P2482 code in my 2018 Chevrolet Silverado?

Diagnosing the P2482 code involves using an OBD-II scanner to confirm the code and then visually inspecting the exhaust gas temperature sensor and its wiring for damage. It may also be necessary to measure the voltage in the sensor circuit to identify whether it is outside the normal range.

What are the steps to repair and clear the P2482 code from a 2018 Chevrolet Silverado?

To repair and clear the P2482 code, first replace or repair any faulty components found during the diagnostic process, such as the exhaust gas temperature sensor or damaged wires. Once repairs are made, use an OBD-II scanner to reset the ECM and clear the code. Test drive the vehicle to ensure the code does not reappear.

Can driving with the P2482 code active damage my 2018 Chevrolet Silverado?

Driving with the P2482 code active can lead to further damage if the issue causing the high voltage condition is not addressed. This could potentially lead to overheating of engine components and additional mechanical failures.

Is it necessary to use OEM parts to replace a faulty exhaust gas temperature sensor in a 2018 Chevrolet Silverado?

While OEM parts are recommended for best compatibility and performance, high-quality aftermarket parts can also be used as long as they meet OEM specifications. Ensure that any replacement parts are compatible with your vehicle model.

What tools are required to diagnose the P2482 code in a 2018 Chevrolet Silverado?

The tools required to diagnose the P2482 code typically include an OBD-II scanner, a multimeter for checking voltages and resistances in the circuit, and basic hand tools for accessing and inspecting the sensor and wiring.
