This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that measures the temperature of the exhaust gases on one side of the engine is not working right. It's like a thermometer that isn't showing the right temperature.
The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. If the sensor reports a temperature that is too low, the car's computer triggers this code.
The P2486 code is set when the Powertrain Control Module (PCM) detects a voltage signal from the exhaust gas temperature sensor that is lower than the expected range. This sensor is located on Bank 2, which is the side of the engine opposite to Bank 1, and it is the fifth sensor in the sequence.
• Check Engine Light illuminated
• Poor fuel economy
• Reduced engine performance
• Faulty exhaust gas temperature sensor
• Wiring issues such as shorts or open circuits
• Corroded or damaged connectors
PCM: Powertrain Control Module, the computer that controls the engine and transmission.
Exhaust Gas Temperature Sensor: A sensor that measures the temperature of the exhaust gases to help control emissions and engine performance.
• 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.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Socket set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain exhaust system components.
• Ensure all electrical connections are secure and free of corrosion.
• Use high-quality fuel to prevent sensor contamination.
Sensor Issue
• Avoid driving with the Check Engine Light on for extended periods.
• Consult a professional mechanic if unsure about repairs.
• Regularly maintain your vehicle to prevent sensor issues.
Check with your vehicle manufacturer for warranty coverage on emission-related components.
This code has been associated with faulty exhaust sensors and wiring issues in vehicles with advanced emission control systems.
Moderate – While the vehicle may still be drivable, it is important to address this issue to prevent potential damage to the catalytic converter.
Driving with a faulty exhaust sensor can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle in a safe location for testing
The exhaust gas temperature sensor is located in the exhaust system on Bank 2, typically after the turbocharger or catalytic converter.
Q: Can I drive my car with a P2486 code?
A: It's possible to drive the car, but it's not recommended as it may lead to further damage and increased emissions.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspection of the exhaust system and sensors can help prevent this issue.

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.
