• P247A
• P247B
The car's computer is saying that one of the sensors that measures how hot the exhaust is getting is reading too high.
The P2482 code is triggered when the vehicle's engine control module (ECM) detects a high voltage signal from the exhaust gas temperature sensor located 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 ECM to adjust fuel injection and timing for optimal performance and emissions. A high circuit code indicates that the sensor is reporting a higher than expected temperature, which could be due to a short circuit, a faulty sensor, or other electrical issues.
• Use an OBD-II scanner to confirm the P2482 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.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter

• Regular maintenance checks
• Ensure proper exhaust system operation
• Avoid driving with a known sensor issue
Sensor Issue
• Get the vehicle diagnosed as soon as possible to avoid further damage.
• Do not ignore the Check Engine Light.
Check with your vehicle manufacturer as this may be covered under emissions warranty.
This code has become more common as vehicles have become more reliant on electronic sensors for emissions control.
Moderate – It should be addressed soon to prevent potential damage to the engine or catalytic converter.
Driving with a malfunctioning exhaust sensor can lead to increased emissions, which may not comply with local regulations.
• Engine at operating temperature
• Vehicle driven under normal conditions
The exhaust gas temperature sensor is typically located in the exhaust manifold or downpipe on Bank 1 of the engine.
Q: Can I drive my car with a P2482 code?
A: It's not recommended to drive for extended periods with this code as it can lead to increased emissions and potential damage.
Q: How do I reset the P2482 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, the code should not return.
