This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a strange reading from a sensor that checks how hot the exhaust gases are on one side of the engine.
The code P247C indicates that the exhaust gas temperature sensor on Bank 2 Sensor 1 is reporting a temperature that is outside the expected range.
P247C is triggered when the Powertrain Control Module (PCM) detects a temperature reading from the exhaust gas temperature sensor on Bank 2 Sensor 1 that is either too high or too low compared to the expected values. This sensor is crucial for monitoring and controlling the emissions and efficiency of the engine.
• Check Engine Light illuminated
• Possible decrease in fuel efficiency
• Potential increase in emissions
• Faulty exhaust gas temperature sensor
• Wiring issues such as shorts or open circuits
• Exhaust leaks near the sensor
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
Exhaust Gas Temperature Sensor: A sensor that measures the temperature of the exhaust gases leaving the engine.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connections to the sensor
• Test the sensor with a multimeter for proper resistance
• Replace the faulty exhaust gas temperature sensor
• Repair or replace damaged wiring
• Fix any exhaust leaks near the sensor
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Tundra
• Regularly inspect exhaust system for leaks
• Ensure sensors are clean and properly connected
• Perform routine maintenance as per vehicle manual
Sensor Issue
• Do not ignore the Check Engine Light
• Get the vehicle diagnosed by a professional
• Avoid driving for extended periods with this issue
Check your vehicle's warranty; emissions-related components may be covered under a longer warranty period.
This code has been reported in vehicles with exhaust system modifications or sensor failures.
Moderate – It should be addressed soon to avoid potential damage to the emissions system.
Ignoring emissions-related issues can lead to failing emissions tests and increased pollution.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The exhaust gas temperature sensor for Bank 2 Sensor 1 is located on the exhaust manifold or pipe on the side of the engine opposite to Bank 1.
Q: Can I drive with a P247C code?
A: It's not recommended to drive for long periods with this code, as it may lead to increased emissions and potential damage to the exhaust system.
Q: How can I prevent a P247C code?
A: Regular maintenance and inspections of the exhaust system can help prevent this code.
