Step-by-step diagnostic guide

Action	Description	Tools Needed
Check for Other Codes	Use an OBD-II scanner to determine if there are additional codes present. These codes may provide additional context or indicate other issues related to the exhaust gas temperature system.	OBD-II Scanner
Inspect Sensor and Wiring Visually	Visually inspect the exhaust gas temperature sensor for signs of physical damage or disconnection. Check the wiring for Bank 1 Sensor 5 for frayed wires, loose connections, or any sign of wear or corrosion.	Flashlight, Safety Gloves
Check for Open Circuit	Use a multimeter to check for continuity in the sensor circuit. If there is no continuity, it indicates an open circuit, which could mean that the wire is broken or disconnected.	Multimeter
Inspect Connectors	Inspect the connectors for secure attachment to the sensor and look for any signs of corrosion, dirt, or wear that could interfere with the electrical connection. Clean or replace connectors as needed to ensure a secure connection.	Contact Cleaner, Replacement Connectors
Test Sensor Functionality	Use a diagnostic tool to verify that the sensor is providing accurate readings when connected. If the sensor is not responding or providing incorrect values, it may need to be replaced.	Diagnostic Tool, Manufacturer’s Specifications
Replace Faulty Sensor or Wiring	If the sensor or wiring is determined to be faulty, replace the sensor or repair/replace any damaged wiring. Ensure the replacement parts meet the manufacturer’s standards and are securely connected.	Replacement Sensor, Basic Hand Tools, Replacement Wiring
Clear Code and Test Drive	Clear the P2480 code using an OBD-II scanner and take the vehicle for a test drive. Monitor the sensor readings to verify that the open circuit issue has been resolved and that the sensor is functioning properly.	OBD-II Scanner, Vehicle Owner’s Manual
Recheck for Codes	After the test drive, re-scan the vehicle with the OBD-II scanner to ensure that the P2480 code has been cleared and no new codes have been detected. If the code persists, further diagnosis may be required.	OBD-II Scanner
