P0C95 Hybrid/EV Battery Temperature Sensor K Circuit High

P0C95 is set when sensor K delivers a voltage above its valid range. In the usual NTC layout a broken circuit allows the bias resistor to drive the input high, so the controller sees an impossibly cold module. In 19OBDG02 (GM, 2019) a reading colder than −69 °C in 8 out of 10 checks counts as failed, Type B; the 2012 Volt table accepts readings only down to −40 °C, equal to an ADC count of 4,000. Mitsubishi names it an open of sensor [10] on the 2018 Outlander PHEV, above 3.97 V for 2 s. Look for a pushed-out terminal, a broken wire or an unplugged connector before replacing parts. Drivers may see reduced electric power or a warning that the battery is too cold. P0C94 is the matching short-circuit code.

Likely causes

Open circuit or disconnected plug at sensor K
Thermistor K open internally
Sensor lead damaged during earlier work on the pack

Symptoms

  • Battery-too-cold or plug-in-to-warm message in mild weather
  • Electric power reduced or unavailable
