This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that measures how hot the exhaust gases are on one side of the engine. It's saying the sensor is reading too high.
The P2487 code indicates that the exhaust gas temperature sensor for bank 2, sensor 5, is reporting a voltage that is higher than the expected range.
The exhaust gas temperature (EGT) sensor is used to monitor the temperature of the exhaust gases leaving the engine. Bank 2 refers to the side of the engine opposite bank 1, and sensor 5 is the fifth sensor in the exhaust system. A high circuit condition means the sensor is sending a higher voltage signal than normal, which could indicate a faulty sensor, wiring issue, or a problem with the exhaust system.
• Check Engine Light is on
• Poor fuel economy
• Possible engine performance issues
• Faulty exhaust gas temperature sensor
• Wiring issues such as shorts or open circuits
• Exhaust leaks affecting sensor readings
Exhaust Gas Temperature Sensor: A sensor that measures the temperature of the exhaust gases.
Bank 2: The side of the engine opposite bank 1, typically the side without cylinder 1.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the exhaust gas temperature sensor with a multimeter.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Fix any exhaust leaks that may be present.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regularly inspect the exhaust system for leaks.
• Ensure sensors are properly maintained.
• Check wiring and connectors for corrosion periodically.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving the vehicle hard until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on emission-related components.
This code has been more common in vehicles with higher mileage or those frequently used for towing.
Moderate – The vehicle may still be drivable, but ignoring the issue could lead to further damage.
Driving with a faulty exhaust sensor may lead to increased emissions, which could be illegal in some regions.
• Engine at operating temperature
• Vehicle in a safe location
The exhaust gas temperature sensor is located in the exhaust system, typically near the catalytic converter on bank 2.
Q: Can I drive with a P2487 code?
A: While you may be able to drive, it's not recommended as it can lead to further damage and increased emissions.
Q: How do I reset the Check Engine Light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes to reset the system.
Budget · Bluetooth scanner
An app-based scanner with repair reports and enhanced system diagnostics on supported vehicles.
Helpful when live data and repair-report guidance can narrow down a drivability issue.

Specialty · Fuel pressure tester
Helpful for no-start, lean, rich, injector, and fuel-delivery diagnosis.
Useful for checking whether fuel delivery is contributing to the fault.

Specialty · Compression tester
Useful when misfire, mechanical condition, or low-cylinder-pressure problems are suspected.
Helpful when you need to rule out low compression or mechanical engine problems.

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.
