DTC codes / P2Axx · Hybrid propulsion / P2A5D
P2A5D indicates that the powertrain control module has detected an abnormally high voltage signal from the outlet temperature sensor of the alternative fuel vaporizer labeled C. This high voltage typically means the sensor circuit is open, shorted to voltage, or the sensor's internal resistance has shifted beyond the expected range for the current temperature.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
