P0C93Hybrid/EV Battery Temperature Sensor K Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0C93 compares sensor K with its neighbours: the reading is electrically fine but too far from the pack average. GM's 2016 hybrid table 16OBDG02 sets it when the absolute difference exceeds 25.00 °C for 50 samples out of 67 taken every 25 ms, roughly 1.7 s, rated Type B; the check is suspended whenever a low, high or erratic code for the battery sensors is active. GM's 2011 table lists K as sensor 11. Mitsubishi handles it on the 2018 Outlander PHEV as a rationality fault of sensor [10]: it needs 3,600 s of soak, a pack temperature from −30 to 60 °C and a 13 °C deviation lasting 0.32 s, tested once per drive. A thermistor that drifted or lost contact with its cells is the typical finding.
- What you may notice
- Warning lamp, often first noticed after a cold start
- Charging and discharging power limited
- Likely causes
- LikelyThermistor K reading off while still electrically valid
- PossibleSensor K lifted off its cell group
- RareReal temperature spread from uneven coolant flow or a weak cell
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
