HV Battery Pack Coolant Temp Sensor

Explicação diagnóstica e técnica
Code P0C42 sets when the control module detects an implausible reading from the sensor measuring coolant temperature at the HV battery pack's liquid-cooling manifold — the value disagrees with the pack's thermistor-string cell-median reading or with the coolant pump's commanded flow rate. Because the manifold sits low in the pack enclosure, the most common physical causes are a coolant leak at the sensor's O-ring seat, which can also introduce a slow drift as coolant level drops, a trapped air pocket at the manifold high point that makes the reading swing implausibly fast, and a thermistor element that has drifted internally. Unlike the pack's cell-group thermistors, this sensor sits in liquid coolant rather than potted against a busbar, so a coolant-side fault points here, not into the module stack.

Estes 21 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 21 vezes.
