Frequently Asked Questions
What does CP_a146 mean on a Tesla?
Tesla's official meaning: charging was interrupted because the charging station reported a fault that prevents the vehicle from charging. Check the station itself for its error code or message; the fix is on the station side in nearly all cases.
How do I fix CP_a146?
Read the station's error indication, try a different stall or station, and report persistent faults to the station operator. If the vehicle charges fine elsewhere — including a Supercharger — the car is not the problem.
Mechanics Guide Step-by-step diagnosis
Step-by-Step Diagnostic Procedure
Check the charging station's display, status lights, or error code, and follow its posted or documented troubleshooting.
Try a different stall, station, or equipment. Per Tesla's official guidance: if the vehicle then charges, the issue was the station; if not, the issue may be with the vehicle.
Per Tesla, this alert is usually specific to the external equipment and doesn't typically indicate a vehicle issue service can resolve.
Note: Tesla documents CP_a139, CP_a141, and CP_a146 with the same meaning and guidance — an equipment-reported fault relayed by the vehicle.
