This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that a temperature sensor in the exhaust system on one side of the engine is not working right. It's like a thermometer that's giving weird readings.
The P247F code indicates that the exhaust gas temperature sensor on bank 2, sensor 4, is reading a temperature that is outside the expected range.
The exhaust gas temperature sensor measures the temperature of the exhaust gases leaving the engine. Bank 2 refers to the side of the engine opposite to bank 1. Sensor 4 is usually located further down the exhaust system, possibly near the catalytic converter or after it. This sensor helps monitor the efficiency of the exhaust system and ensures that emissions are within the required limits. When the sensor reads a temperature that is too high or too low compared to the expected range, the P247F code is triggered.
• 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 temperature readings
Bank 2: The side of the engine opposite to bank 1, usually the side without cylinder 1.
Sensor 4: Typically the sensor located further down the exhaust system, often near or after the catalytic converter.
• Use an OBD-II scanner to confirm the code.
• Inspect the exhaust gas temperature sensor and its wiring for damage.
• Test the sensor using a multimeter to check for proper resistance.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Fix any exhaust leaks that may be affecting sensor readings.
• OBD-II scanner
• Multimeter
• Wrench set
$150 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Ram 1500
• Regularly inspect exhaust system components.
• Ensure sensors are clean and free from debris.
• Perform routine vehicle maintenance.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Keep up with regular maintenance to prevent sensor issues.
Sensor-related repairs may be covered under emissions warranty if the vehicle is within the warranty period.
This code has been associated with issues in vehicles with complex exhaust systems, especially those with multiple catalytic converters.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Driving with a malfunctioning exhaust sensor may lead to increased emissions, which could be illegal in some areas.
• Engine at operating temperature
• Vehicle running at idle
The exhaust gas temperature sensor is located on the exhaust system of bank 2, typically near or after the catalytic converter.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor fuel economy and potential engine performance issues.
Q: Can I drive my car with this code?
A: While you may be able to drive, it's best to have it checked to avoid further issues.
Budget · Enhanced code reader
A wired color-screen reader with readiness hotkeys, live data, code definitions, and data logging.
Good for emissions-related codes because it exposes readiness monitors and live powertrain data.

Specialty · Smoke machine
Helpful for finding EVAP and vacuum leaks that are hard to see with visual inspection alone.
Helpful for tracking down EVAP and vacuum leaks that can trigger emissions faults.

Specialty · O2 sensor socket
Helpful when the code points toward exhaust or oxygen-sensor work and space is tight.
Useful when the diagnosis points toward oxygen-sensor removal or replacement.

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.
