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.
High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
Symptoms
- Hybrid or EV warning message
- Reduced electric power until the fault is repaired
Most likely causes
- Poor contact at the sensor K plug
- Thermistor K failed
- Defective input channel on the cell monitoring board
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- It can trigger limp mode.
- It affects emissions.
What each character of P0C92 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- C: Subsystem depends on the code range
- 92: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0C92?
