Quick answer

For a 2013 Chevrolet Volt (US), verified GM bulletin 18-NA-342 identifies P0C7E as Hybrid/EV Battery Temperature Sensor 7 Circuit Low Voltage. The supplied record’s title/meaning appears inconsistent with the bulletin evidence, which separates P0C7E (sensor 7) from sensor 8 codes P0C82–P0C84.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P0C7E mean?

For a 2013 Chevrolet Volt (US), verified GM bulletin 18-NA-342 identifies P0C7E as Hybrid/EV Battery Temperature Sensor 7 Circuit Low Voltage. The supplied record’s title/meaning appears inconsistent with the bulletin evidence, which separates P0C7E (sensor 7) from sensor 8 codes P0C82–P0C84.

2. Technical explanation

NHTSA-hosted GM manufacturer communication 18-NA-342 lists the Battery Temperature Sensor 7 codes as: P0C7D, performance; P0C7E, circuit low voltage; and P0C7F, circuit high voltage. The same bulletin lists Battery Temperature Sensor 8 codes as P0C82, performance; P0C83, circuit low voltage; and P0C84, circuit high voltage. No further diagnostic mechanism, test procedure, or repair instruction is established by the supplied verified evidence.

3. What system is affected?

Hybrid/EV battery temperature sensor 7 circuit, according to GM bulletin 18-NA-342.

4. How serious is this code?

Unknown. The supplied diagnostic record does not establish severity.

5. Symptoms you may notice

Not yet established by verified evidence.

6. Possible causes
