Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that could provide further context or information about other issues that may be contributing to this code. | OBD-II Scanner |
| Inspect Sensor and Wiring Visually | Examine the exhaust gas temperature sensor for any visible physical damage, such as cracks or deformation. Inspect the wiring for Bank 2 Sensor 2 for signs of wear, fraying, or corrosion that could contribute to the issue. | Flashlight, Safety Gloves |
| Test Sensor Output | Use a diagnostic tool to monitor real-time data from the exhaust gas temperature sensor while the engine is running. Compare the readings to the manufacturer’s specifications to see if the sensor is providing values that are outside the acceptable range. | Diagnostic Tool, Manufacturer’s Specifications |
| Check Sensor Circuit Continuity | Use a multimeter to test the continuity and resistance of the sensor circuit. Check for open circuits, shorts, or any resistance issues that could lead to inaccurate sensor readings. | Multimeter |
| Inspect Connectors | Inspect the connectors for secure attachment, cleanliness, and signs of corrosion. Clean the connectors using contact cleaner if necessary, and replace any connectors that are damaged or show corrosion. | Contact Cleaner, Replacement Connectors |
| Replace Faulty Sensor or Components | If the sensor or any wiring is found to be defective, replace the faulty components using manufacturer-approved parts. Ensure that all connections are properly secured to avoid future issues. | Replacement Sensor, Basic Hand Tools |
| Clear Code and Test Drive | Clear the P247D code using an OBD-II scanner, and then take the vehicle for a test drive. Monitor the exhaust gas temperature readings during the drive to confirm that the sensor is functioning properly and providing correct data. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, use the OBD-II scanner again to ensure that the P247D code has been cleared and no new codes have appeared. If the code persists, additional diagnostics will be necessary. | OBD-II Scanner |
