This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with a sensor that measures how hot the exhaust gases are. It's like a thermometer for the car's exhaust, and it's not working right.
The P2480 code indicates an issue with the exhaust gas temperature sensor circuit, specifically an open circuit in Bank 1 Sensor 5.
The exhaust gas temperature sensor measures the temperature of the exhaust gases leaving the engine. This information is used by the engine control module (ECM) to optimize engine performance and control emissions. An open circuit means there is a break in the electrical path, preventing the sensor from sending data to the ECM.
• Check Engine Light is on
• Poor engine performance
• Increased emissions
• Faulty exhaust gas temperature sensor
• Damaged wiring or connectors
• ECM issues
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the exhaust gas temperature sensor for functionality.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance checks
• Ensure proper sensor installation
• Avoid harsh driving conditions
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle until repaired.
Check with your vehicle manufacturer for specific warranty coverage on emissions-related components.
This code has been more common in vehicles with high mileage or those exposed to extreme conditions.
Moderate – It should be addressed soon to avoid potential engine damage.
Ignoring this issue can lead to increased emissions, which may not comply with legal standards.
• Engine at operating temperature
• Vehicle in park or neutral
The exhaust gas temperature sensor is typically located in the exhaust manifold or near the catalytic converter.
Q: Can I drive with a P2480 code?
A: It's not recommended to drive with this code as it can lead to engine performance issues and increased emissions.
Q: How do I clear a P2480 code?
A: The code can be cleared using an OBD-II scanner after the issue is fixed, but it may return if the problem persists.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
