P247E
Exhaust Gas Temperature Out of Range Bank 2 Sensor 3
Auxiliary emissions control
Generic OBD-II
Medium
What it means
P247E means the bank 2, sensor 3 exhaust gas temperature reading has moved outside the range the engine computer expects. The sensor protects the turbo, catalyst, and particulate filter from overheating, so an out-of-range value usually traces to a failing sensor, a poor connection, or damaged wiring rather than an engine fault.
Medium
Can I keep driving? The engine starts and runs, but the ECM may limit boost or particulate-filter regeneration while the temperature reading sits outside its valid range.
Common symptoms
What you'll notice
- Check-engine light on
- Temperature reading stuck too high or too low versus the other EGT sensors
- Possible reduced power or blocked regeneration
- No change in starting behaviour
Common causes
Most likely first
- Failing exhaust gas temperature sensor at bank 2, sensor 3Likely
- Corroded or high-resistance connection shifting the reading out of rangeCommon
- Wiring shorted, open, or grounded near the exhaustCommon
- Soot or exhaust contamination on the sensor tipLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and find the bank 2, sensor 3 EGT sensor.
- On a cold engine, compare all EGT readings; the faulty sensor stands out from the group.
- Inspect the connector and harness for heat damage, corrosion, or an open/short.
- Verify signal, reference, and ground at the sensor against spec.
- Replace the EGT sensor when wiring is confirmed good, then clear and road-test.
FAQ
Quick answers
Is it safe to drive with P247E?+
Short trips are usually fine, but the ECM may cap boost or skip regeneration to protect the exhaust, so get it fixed before the filter loads up.
Can I just clear P247E?+
It comes back as soon as the computer sees the out-of-range temperature again. Repair the sensor or wiring first.
