1. What does P0807 mean?
For a 2016–2017 Chevrolet Volt (US), DTC P0807 is covered by GM bulletin 16-NA-400. The bulletin states that a loss of propulsion may occur with P0807. The supplied evidence is truncated and does not establish the complete diagnostic criteria or repair procedure.
2. Technical explanation
NHTSA-hosted manufacturer communication 16-NA-400 identifies P0807 among codes that may be associated with loss of propulsion. It instructs technicians to review Hybrid Powertrain Control Module (HPCM) freeze-frame information. The visible bulletin evidence states that there should be no additional DTCs stored in the HPCM, while P0AC4 will be stored in the ECM to request MIL illumination. Further conditions and the prescribed resolution are not present in the supplied evidence.
3. What system is affected?
Hybrid Powertrain Control Module (HPCM) and Engine Control Module (ECM) are referenced by the verified bulletin evidence. A specific failed component or system name is not yet established by verified evidence.
4. How serious is this code?
Potentially serious: the verified bulletin states that vehicles may have a loss of propulsion with P0807. The database severity value is unknown.
5. Symptoms you may notice
- Loss of propulsion may occur.
- A P0AC4 may be stored in the ECM to request MIL illumination, under the freeze-frame condition described in the bulletin.
6. Possible causes
- Not yet established by verified evidence. The supplied bulletin excerpt does not provide a complete cause determination for P0807.
7. Can I still drive the vehicle?
Not yet established by verified evidence. Because loss of propulsion may occur, arrange professional evaluation rather than relying on normal operation.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- If propulsion is lost, move to a safe location when traffic conditions permit and follow the vehicle’s on-screen warnings.
- Have the vehicle evaluated by a Chevrolet/GM-qualified service facility.
- Do not attempt high-voltage diagnosis or repair.
10. Step-by-step troubleshooting
- A qualified technician should review HPCM freeze-frame information, as specified in bulletin 16-NA-400.
- The visible bulletin criteria include no additional DTCs stored in the HPCM and P0AC4 stored in the ECM requesting MIL illumination.
- The remaining freeze-frame criteria and next diagnostic steps are not included in the supplied evidence.
11. When to contact service
Contact a Chevrolet dealer or qualified GM service facility promptly, especially if loss of propulsion has occurred.
12. What the service center may check
- Retrieve and document DTCs from the HPCM and ECM.
- Review HPCM freeze-frame data.
- Verify whether there are no additional HPCM DTCs and whether P0AC4 is stored in the ECM, as described in bulletin 16-NA-400.
13. Possible repair or resolution
- Not yet established by verified evidence. The supplied excerpt does not include the bulletin’s complete repair resolution for P0807.
