What does code P2EA3 mean?

Q: What does code P2EA3 mean?

Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 6. P2EA3 indicates that the powertrain control module has detected an abnormally low voltage signal from the exhaust gas temperature sensor located at bank 1 sensor 6, which is a downstream sensor on that bank. The computer expects the sensor's internal thermistor to produce a voltage within a specific range as exhaust temperature rises, and a low signal typically means the circuit is shorted to ground or the sensor element has failed.
