| Code | Information |
|---|---|
| Meaning | P247C: Exhaust Gas Temperature Out of Range Bank 2 Sensor 1 |
| Is it serious? | Yes, this code may lead to incorrect exhaust gas temperature readings, which can affect engine performance and cause higher emissions. |
| Possible causes | – Exhaust gas temperature reading is out of expected range for Bank 2 Sensor 1 – Faulty sensor – Issues with the sensor circuit |
| How to diagnose? | – Inspect the exhaust gas temperature sensor for Bank 2 Sensor 1 – Check the sensor circuit for any issues – Replace faulty components if needed |
P247C Meaning
The P247C: Exhaust Gas Temperature Out of Range Bank 2 Sensor 1 code indicates that the temperature readings being provided by Bank 2 Sensor 1 are not within the expected range. This could be caused by a defective sensor, damaged wiring, or issues within the sensor circuit, resulting in unreliable data that affects exhaust temperature control and may lead to reduced engine efficiency or emission issues.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if there are any other related diagnostic trouble codes present. These codes may provide more information about any additional issues that could be affecting the sensor. | OBD-II Scanner |
| Inspect Sensor and Wiring Visually | Visually inspect the exhaust gas temperature sensor for any signs of physical damage, such as cracks, deformation, or soot buildup. Inspect the wiring for Bank 2 Sensor 1 for fraying, corrosion, or loose connections that might be affecting sensor performance. | Flashlight, Safety Gloves |
| Test Sensor Output | Use a diagnostic tool to monitor real-time readings from the exhaust gas temperature sensor for Bank 2 Sensor 1 while the engine is running. Compare these readings against the manufacturer’s specifications to determine if the sensor is providing values that are out of range. | Diagnostic Tool, Manufacturer’s Specifications |
| Check Sensor Circuit Continuity | Use a multimeter to test the continuity and resistance of the sensor circuit. Ensure there are no shorts, open circuits, or other electrical issues that could be affecting sensor accuracy. | Multimeter |
| Inspect Connectors | Verify that all connectors are properly attached to the sensor and free of debris, corrosion, or damage. Use contact cleaner to remove any contaminants, and replace any connectors that are damaged to ensure a stable connection. | Contact Cleaner, Replacement Connectors |
| Replace Faulty Sensor or Components | If the sensor is found to be faulty or the wiring is damaged, replace the faulty parts using manufacturer-approved replacements. Ensure all connections are secure after replacement. | Replacement Sensor, Basic Hand Tools |
| Clear Code and Test Drive | Clear the P247C code using an OBD-II scanner and take the vehicle for a test drive. Monitor the exhaust gas temperature readings to ensure that the sensor is functioning properly and within the expected range. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After completing the test drive, use an OBD-II scanner to confirm that the P247C code has been cleared and no new issues have arisen. If the code returns, further diagnostic work will be necessary to identify the cause. | OBD-II Scanner |
