P0C96Hybrid/EV Battery Temperature Sensor K Circuit Intermittent/Erratic
- 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
- P0C96 flags an unsteady sensor K signal, the kind of noise a loose contact produces while the value still sits inside its valid band. GM describes the monitor in 16OBDG02 and 18OBDG02: each 100 ms sample adds to a running total of absolute changes across 10 samples, a total above 10 marks the window as failed, and 4 failed windows in 5 store the code, Type B, so two bad trips are needed. Supply over 10.2 V and intact communication with the battery interface module are prerequisites. Mitsubishi defines no erratic code for its sensor [10]. Moving the harness by hand while a scan tool shows the value often reveals the cause. P0C94 and P0C95 cover faults where the signal stays out of range.
