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.

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

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

Most likely causes

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

What to check, in order

Start with the simplest. You can tick off each step.

Read the codes with a hybrid-compatible scanner and write down the freeze frame data
Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
Make sure the battery cooling air intake is clean
Check the 12 V auxiliary battery, which can also trigger warnings
Leave any high-voltage measurements to a specialized repair shop

Good to know

It can trigger limp mode.
It affects emissions.

What each character of P0C95 means

P: Powertrain: engine and transmission
0: Generic code: same on every make
C: Subsystem depends on the code range
95: Specific fault in that system
