What P0C92 means
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.
P0C92 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0C92
- Hybrid or EV warning message
- Reduced electric power until the fault is repaired
Common causes of P0C92
- Most likelyPoor contact at the sensor K plug
- PossibleThermistor K failed
- Less likelyDefective input channel on the cell monitoring board
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C92 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| 92 | The exact fault in that area. |
What to do next
- Note P0C92 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0C92
What does P0C92 mean?
P0C92 means "Hybrid/EV Battery Temperature Sensor K Circuit". P0C92 is stored when the input from battery temperature sensor K has an electrical fault that the controller leaves unclassified. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C92?
Drive gently and only to a workshop. With P0C92 the car can go into limp mode (reduced power) to protect itself.
Will P0C92 fail an emissions test?
Yes, it can. P0C92 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0C92 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0C92 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
