Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.
What does CP-A113 mean?
Tesla alert code in the Charge Port (CP) module. A short circuit has been detected on the inlet heater hardware The current going through the inlet heater was higher than 4.5A Setting the UI defrost command to low The inlet heater won't be enabled which might lead to the charge port staying frozen Expected GTW CAN messages are missing Inductive sensor and potentiometer readings of door presence do not match IEC combo charge session shutdown occurred Pilot sensor readings are unexpected.

Affected Tesla Models
What You May Notice
- Charge port alert: A short circuit has been detected on the inlet heater hardware The current going through the inlet heater was higher tha
- Charging session may be interrupted or not starting as expected
- Charge port light flashing amber or red
How to Diagnose and Resolve
- 1 Unplug and re-plug the charge cable
- 2 Try a different charging cable or Supercharger stall
- 3 Reboot the vehicle and attempt to charge again
- 4 If "A short circuit has been detected on the inlet hea" persists, contact Tesla Roadside Assistance
- 5 Schedule a Service Center visit if the problem continues
Severity Notes
CP-A113 is an Alert in the Charge Port system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
