P247D
Exhaust Gas Temperature Out of Range Bank 2 Sensor 2
Exhaust temperature (emissions)
Generic OBD-II
Medium
What it means
P247D means the exhaust gas temperature (EGT) sensor for bank 2, sensor 2 is reporting a value outside its plausible range. The engine computer uses these readings to protect the catalyst and particulate filter and to time regeneration, so the fault is usually a sensor or wiring issue rather than an engine mechanical problem.
Medium
Can I keep driving? The car will usually still drive, but the exhaust-temperature reading can't be trusted, which can interrupt regeneration and cause reduced power on some vehicles.
Common symptoms
What you'll notice
- Check-engine light on
- Possible reduced power or limp mode on diesels
- Failed or incomplete DPF/catalyst regeneration cycles
- Frequently no noticeable driving symptom
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor on bank 2, sensor 2Likely
- Open, shorted, or high-resistance wiring in the sensor circuitCommon
- Corroded or loose sensor connectorCommon
- Heat- or vibration-damaged harness near the exhaustLess often
- Rarely, an ECM faultLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and locate the bank 2 / sensor 2 EGT sensor.
- Inspect the sensor, connector, and wiring for heat damage or corrosion.
- Compare the live temperature reading with the other EGT sensors when cold — they should agree.
- Repair wiring or connector faults before replacing parts.
- Replace the EGT sensor if its reading stays out of range, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P247D?+
Short trips are usually fine, but this sensor helps protect the exhaust and manage regeneration, so have it repaired soon.
Can I just clear P247D?+
It will return until the sensor or wiring is fixed. Clearing only turns the light off for a while.
