P062F: Internal Control Module EEPROM Error
2 vehicles · 2 makes
Most Reported On
P062F is an OBD-II diagnostic trouble code meaning “Internal Control Module EEPROM Error.” P062F sets when the ECM, TCM, or another control module detects a fault in its internal EEPROM (Electrically Erasable Programmable Read-Only Memory). The EEPROM stores calibration settings, learned/adaptive values, and software parameters; when the module's self-test finds this memory cannot be reliably read or written, it stores P062F. It is an internal module fault, not an external circuit issue. This code is most commonly reported on 2017-2019 Toyota Highlander (LE, XLE, SE, Limited, Limited Platinum), and 2019-2020 Honda Civic (Sedan, Coupe, Hatchback, Sport, EX, Touring, Si).

FAQ
What does P062F mean?
P062F stands for "Internal Control Module EEPROM Error." P062F sets when the ECM, TCM, or another control module detects a fault in its internal EEPROM (Electrically Erasable Programmable Read-Only Memory). The EEPROM stores calibration settings, learned/adaptive values, and software parameters; when the module's self-test finds this memory cannot be reliably read or written, it stores P062F. It is an internal module fault, not an external circuit issue.
What are the most common causes of P062F?
The most common causes of P062F are: Internal control module (ECM/TCM) hardware/memory failure, Corrupted EEPROM data from an interrupted or failed reflash, Voltage spikes or unstable power/ground to the module, Water intrusion or corrosion in the module, Aged module with degraded memory cells. The specific cause varies by vehicle.
How much does it cost to fix P062F?
Repair costs vary widely depending on the root cause and vehicle.
