P0C36Hybrid/EV Battery Temperature Sensor F Circuit High
- 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
- P0C36 means the voltage from battery temperature sensor F sits above its valid range. With GM's NTC thermistor and pull-up, an open circuit, a broken wire or an unplugged connector pulls the input up and reads as an impossibly cold cell group. GM's 2016 table fails it below −69 °C in 8 of 10 samples, the Volt battery tables of 2016 to 2019 below −40 °C for 1.4 s within 2 s, and the eAssist table above 4.63 V, about −45 °C, in 7 of 10 samples, each as Type B, two trips. Volt bulletin 18-NA-342 lists it as sensor 6 circuit high voltage and links the F group to a Battery Too Cold message. The counterpart for a short to ground is P0C35. Expect limited power and possibly pack heating that is not needed.
- What you may notice
- MIL after two trips
- Battery too cold, plug in to warm message
- Reduced electric power
- Likely causes
- LikelyOpen circuit or unlatched connector of sensor F
- PossibleThermistor F open internally
- RareModule software setting the code falsely in the cold (GM Volt)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
