This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady reading from a sensor that measures how hot the exhaust is coming out of the engine.
The P2081 code is triggered when the Engine Control Module (ECM) detects an intermittent signal from the exhaust gas temperature sensor located in Bank 1, Sensor 1.
The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases as they leave the engine. This information is used by the ECM to optimize fuel efficiency and emissions. An intermittent circuit issue indicates that the sensor signal is not stable, which can lead to incorrect readings and affect engine performance.
• Check Engine Light illuminated
• Poor fuel economy
• Engine performance issues
• Faulty exhaust gas temperature sensor
• Damaged or corroded wiring or connectors
• Faulty ECM
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 or corrosion.
• Test the exhaust gas temperature sensor for proper operation.
• 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
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain exhaust system components.
• Keep wiring and connectors clean and free from corrosion.
• Perform regular vehicle diagnostics to catch issues early.
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light comes on.
• Avoid driving the vehicle hard until the issue is resolved.
• Regular maintenance can prevent sensor issues.
Sensor issues may be covered under emissions warranty. Check with the manufacturer.
This code has been associated with faulty sensors and wiring issues in multiple vehicle models over the years.
Moderate – It is important to address this issue to prevent further engine performance problems.
Ignoring this code can lead to increased emissions and may not pass emissions testing.
• Engine at operating temperature
• Vehicle in a safe and stationary position
The exhaust gas temperature sensor is located in the exhaust manifold or near the turbocharger on Bank 1.
Q: What does Bank 1 mean?
A: Bank 1 refers to the side of the engine where cylinder 1 is located.
Q: Can I drive with a P2081 code?
A: It's possible, but not recommended as it may affect engine performance and emissions.
