Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 4

Where it lives

For P2476, the sensor sits on the circuit this code reports. The description of P2476 puts it on bank 2.

Check these first

• An exhaust gas temperature sensor bank 2 sensor 4 reading too high
• An open in the exhaust gas temperature sensor bank 2 sensor 4 signal circuit
• An exhaust leak ahead of the sensor
• Heavy particulate matter buildup on the sensor

What to do next

1. Read exhaust gas temperature sensor bank 2 sensor 4 on a scan tool
2. Compare the reading against the other exhaust gas temperature sensors
3. Inspect the exhaust for leaks ahead of the sensor
4. Inspect the sensor connector and wiring
5. Replace the exhaust gas temperature sensor if the reading stays too high
6. Clear the code and retest
