Exhaust Gas Temperature Out of Range Bank 2 Sensor 2
The P247D code indicates that the exhaust gas temperature (EGT) sensor on Bank 2, Sensor 2 (downstream of the diesel particulate filter or catalytic converter) is reporting a temperature outside the expected range. This can be caused by a faulty sensor, wiring issues, or actual exhaust temperature extremes. The sensor is critical for monitoring exhaust aftertreatment systems and preventing damage.
01. Most Common Causes
- Faulty exhaust gas temperature sensor
- Damaged or corroded wiring/connector
- Exhaust leak near the sensor
- Engine running too hot or too cold
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced fuel economy
- Possible limp mode or reduced engine power
- Failed emissions test
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the EGT sensor and wiring for damage.
Step 3: Compare sensor readings with a scan tool to expected values.
Step 4: Test sensor resistance and voltage per manufacturer specs.
