P2469
Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 3
Exhaust temperature (emissions)
Generic OBD-II
Medium
What it means
P2469 means the exhaust gas temperature (EGT) sensor for bank 2, sensor 3 is sending a signal that's too high, usually pointing to an open circuit or wiring fault. These sensors help the engine protect the exhaust and manage particulate-filter regeneration, so the fault is about monitoring rather than a running engine problem.
Medium
Can I keep driving? The car will usually still drive, but exhaust-temperature monitoring is unreliable, which can disrupt DPF regeneration and may trigger reduced power on some vehicles.
Common symptoms
What you'll notice
- Check-engine light on
- Possible reduced power or limp mode on diesels during regeneration
- Failed or incomplete DPF/catalyst regeneration cycles
- No noticeable driving symptoms in many cases
Common causes
Most likely first
- Faulty exhaust gas temperature (EGT) sensor on bank 2, sensor 3Likely
- Open or short in the EGT sensor wiring (reads as high voltage)Common
- Corroded or loose sensor connectorCommon
- Heat-damaged wiring 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 3 EGT sensor in the exhaust.
- Inspect the sensor connector and wiring for heat damage, corrosion, or an open circuit.
- Check the sensor's resistance and signal against the manufacturer's spec with a scan tool.
- Repair damaged wiring or connectors before condemning the sensor.
- Replace the EGT sensor if it's out of range with good wiring, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2469?+
Short-term usually yes, but exhaust-temperature protection and DPF regeneration rely on this sensor, so have it repaired before long or heavy driving.
Can I just clear P2469?+
It returns until the sensor or its wiring is fixed. Clearing only turns the light off temporarily.
