DTC codes / P2Exx · Hybrid propulsion / P2EA1
P2EA1 indicates that the powertrain control module has detected an abnormal condition in the exhaust gas temperature sensor circuit for bank 1 sensor 6, which is typically a post-catalyst or downstream sensor on that bank. The computer compares the sensor signal to expected values and sets this code when the voltage or resistance falls outside the programmed range for a calibrated time.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
