Frequently Asked Questions
What does CP_a141 mean on a Tesla?
Tesla's official meaning: charging was interrupted because the external charging equipment reported a fault that prevents charging. Check the equipment itself for its error code or message — the fix is on the equipment side in nearly all cases.
How do I fix CP_a141?
Read the equipment's own error indication and follow its manual. Try another charger or station to confirm the vehicle is fine — if it charges elsewhere, the original equipment was the problem.

Step-by-Step Diagnostic Procedure
Check the charging equipment's status lights, display, or error code and follow its own manual's troubleshooting.
Try different charging equipment or a different station. Per Tesla's official guidance: if the vehicle then charges, the issue was the equipment; 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 — the vehicle relays an equipment-reported fault in all three cases.
