The P247E: Exhaust Gas Temperature Out of Range Bank 2 Sensor 3 refers to an issue where the exhaust gas temperature reading from Bank 2 Sensor 3 is detected to be outside the expected range. This could be due to a malfunctioning sensor, problems with the sensor circuit, or wiring issues, which may result in incorrect temperature monitoring, potentially affecting engine performance and emissions control.
P247E – Quick Overview
| Code | Information |
|---|---|
| Meaning | P247E: Exhaust Gas Temperature Out of Range Bank 2 Sensor 3 |
| Is it serious? | Yes, incorrect exhaust temperature readings can impact engine efficiency, lead to increased emissions, and affect overall engine performance. |
| Possible causes | – Exhaust gas temperature reading is out of expected range for Bank 2 Sensor 3 – Faulty sensor – Issues with the sensor circuit |
| How to diagnose? | – Inspect the exhaust gas temperature sensor for Bank 2 Sensor 3 – Check the sensor circuit for any issues – Replace faulty components if needed |
P247E Meaning
The P247E: Exhaust Gas Temperature Out of Range Bank 2 Sensor 3 code indicates that the sensor responsible for measuring the exhaust gas temperature at Bank 2 Sensor 3 is sending readings that are outside the normal range. This may be caused by a defective sensor, damaged wiring, or a circuit issue, resulting in unreliable exhaust gas data, potentially impacting engine efficiency and emissions management.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if there are any additional related diagnostic codes that could help identify other underlying issues contributing to this fault. | OBD-II Scanner |
| Inspect Sensor and Wiring Visually | Visually inspect the exhaust gas temperature sensor for signs of physical damage, such as cracks, soot buildup, or any deformities. Examine the wiring for Bank 2 Sensor 3 for fraying, corrosion, or loose connections that might affect sensor performance. | Flashlight, Safety Gloves |
| Test Sensor Output | Use a diagnostic tool to monitor real-time sensor output from the exhaust gas temperature sensor for Bank 2 Sensor 3 while the engine is running. Compare these readings with the manufacturer’s specifications to determine if the sensor is functioning correctly. | Diagnostic Tool, Manufacturer’s Specifications |
| Check Sensor Circuit Continuity | Use a multimeter to verify the continuity of the wiring and ensure there are no open circuits, shorts, or high resistance that could cause the sensor to read out of range. | Multimeter |
| Inspect Connectors | Inspect all connectors leading to the sensor for secure attachment, cleanliness, and signs of corrosion or wear. Clean any dirty connectors with contact cleaner, and replace them if they are damaged. | Contact Cleaner, Replacement Connectors |
| Replace Faulty Sensor or Components | If the sensor or related wiring is found to be faulty, replace the defective component with a manufacturer-approved replacement. Ensure that all new components are properly installed and secured. | Replacement Sensor, Basic Hand Tools |
| Clear Code and Test Drive | Clear the P247E code using an OBD-II scanner and then take the vehicle for a test drive. Monitor the exhaust temperature readings during the drive to verify that the sensor is now functioning correctly and providing readings within the expected range. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After completing the test drive, re-scan the vehicle using an OBD-II scanner to confirm that the P247E code has been cleared and no new codes have appeared. If the code returns, further diagnostics may be necessary to identify any additional underlying issues. | OBD-II Scanner |
