DTC codes / P2Axx · Hybrid propulsion / P2A5A
P2A5A indicates that the powertrain control module has detected an abnormal signal from the outlet temperature sensor of the alternative fuel vaporizer designated as 'C'. This sensor monitors the temperature of the fuel vapor after it leaves the vaporizer, and the circuit's voltage or resistance falls outside the expected range for the current operating conditions.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
