What it means
The control module monitors the exhaust gas temperature signal from bank 2 sensor 3 and compares it with expected values. It sets this code when the signal is outside the expected range or does not respond plausibly to operating conditions.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
Bank 2 sensor 3 measures exhaust gas temperature so the control module can assess conditions around the emissions system. P2467 sets when its signal is electrically present but outside the expected range or does not change plausibly with operating conditions.
Common causes
Most likely first.
- Faulty exhaust gas temperature sensor
- Damaged wiring or poor connector contact
- Exhaust leak near the sensor
- Abnormal exhaust temperature
Symptoms
- Check engine light on
- DPF or emissions warning light may come on
- Reduced power or limited regeneration may occur
- Increased fuel consumption
How to diagnose it
- Save freeze-frame data and compare bank 2 sensor 3 live temperature with engine load and other exhaust temperature readings.
- With the engine cold, check whether bank 2 sensor 3 reports a plausible temperature relative to ambient and nearby sensors.
- Inspect the bank 2 sensor 3 connector and heat-exposed wiring for corrosion, loose pins, chafing, or melted insulation.
- Check for exhaust leaks near bank 2 sensor 3 that could affect the temperature reading, and look for conditions that could cause unusually high or low exhaust heat.
- Test the sensor circuit and compare sensor resistance or signal behavior with the manufacturer's specification.
- If the circuit and sensor pass checks, investigate related engine or DPF faults that could produce abnormal exhaust temperatures.
Common fixes
- Repair a loose or corroded bank 2 sensor 3 connector.
- Repair damaged or heat-exposed wiring in the sensor circuit.
- Repair an exhaust leak near bank 2 sensor 3.
- Replace bank 2 sensor 3 if its signal remains outside the manufacturer's specification.
- Correct an engine or DPF fault that is causing genuinely abnormal exhaust temperature.
Can I keep driving?
Drive gently and avoid heavy loads if the DPF or emissions warning appears, since regeneration may be limited when bank 2 sensor 3 readings are implausible. Have it diagnosed soon to reduce the risk of emissions-system damage or worsening drivability.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
