What does CP-A125 mean?

Tesla alert code in the Charge Port (CP) module. The charge port is unexpectedly not allowed to use high power from LV bus Charge port is not allowed to use high power from the LV bus Charge port is granted permission to use high power from LV bus Charge port latch, door, and inlet heater will not behave as expected The charge port either timed out during a mode request or failed to enter the requested mode Charge port detected a unexpected fast rise in temperature Charge port thermal velocity (calculated each minute) exceeds the expected rise in temperature. Once the charge cable is connected Thermistor is greater than the open circuit threshold and, if short circuit detection is supported, less than the short circuit threshold for at least one second Continued charging may result in damage to the vehicle The CP has detected a hardware condition that would prevent the microcontroller from going to sleep The CP has detected that the Gen 2 Wall Connector has measured a temperature at which AC charging should begin to fold back info from manualCP_A101 The Gen 2 Wall Connector reports a temperature greater than 80C Charge Port door potentiometer damaged info from manualCP_A043 The CP door potentiometer behaves erratically The CP door behaves rationally through several door cycles Charge port door may not open or close as designed Cable proximity did not latch within the expected timeframe Cable proximity remains unlatched for an unexpected long duration Cleared when proximity changes from unlatched The CP is unable to confirm the state of the charge cable

Original Description

Severity Notes

CP-A125 is an Alert in the Charge Port system. It is generally safe to continue driving, but have it checked at your next scheduled service.
