Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 2

Where it lives

For P2084, the description names the sensor as the part involved. The description of P2084 puts it on bank 1.

Check these first

• An exhaust gas temperature sensor bank 1 sensor 2 reading out of range
• An open or short in the exhaust gas temperature sensor bank 1 sensor 2 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 1 sensor 2 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 out of range
6. Clear the code and retest
