P0C92 is stored when the input from battery temperature sensor K has an electrical fault that the controller leaves unclassified. Public manufacturer documentation for exactly this code does not exist. In GM's 2011 rationality list K appears as sensor 11 of sixteen, and GM's later hybrid tables from 2012 up to 19OBDG02 only define the specific K codes P0C93 to P0C96. Mitsubishi maps K to module sensor [10] on its plug-in Outlander and there, too, distinguishes only rationality, short and open. The legal basis is CARB paragraph (e)(15.3.1), which calls for permanent checks of plausible values and wiring continuity. Diagnosis covers the thermistor, its leads and the plug at the monitoring board, all inside the traction battery, after it has been made safe.

Likely causes

Poor contact at the sensor K plug
Thermistor K failed
Defective input channel on the cell monitoring board

Symptoms

  • Hybrid or EV warning message
  • Reduced electric power until the fault is repaired
