Drive Motor Inverter Temp Sensor

Explicação diagnóstica e técnica
Code P0AED sets when the control module detects an implausible reading from the NTC thermistor bonded to the drive motor inverter's IGBT (or SiC MOSFET) power-module baseplate — the reading disagrees with the commanded switching load or drifts outside the sensor's calibrated curve. The most common physical causes are degraded thermal-interface paste between the power module and its cold plate, which raises the true junction temperature well above what the coolant loop shows, a restricted or air-locked coolant passage specific to the inverter's cold plate, and a corroded NTC lead connector on the low-voltage control board. Because this sensor feeds the derate-then-shutdown ladder that protects the switching devices, a stuck-low reading can mask a real overtemperature condition and should be cross-checked against coolant-loop temperature before the sensor is condemned.

Estes 40 códigos de diagnóstico compartilham um mesmo mecanismo de detecção e um mesmo caminho de reparo; por isso o MechanicDB os agrupa em uma única família de falhas redigida, em vez de repetir a mesma explicação 40 vezes.
