P062F on Honda
Internal Control Module EEPROM Error
P062F on Honda vehicles indicates internal control module eeprom error. Au7o has documented this code across 1 Honda model — most commonly on Civic. 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.
Common Causes of P062F
- •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

- Denso Low-Density Impeller Fuel Pump Failure — Engine Stall (Recall 23V-858)2019-2020
Certain Civics use a Denso in-tank fuel-pump module whose impeller was molded from improper-density resin. The impeller absorbs fuel, swells and deforms, then binds against the pump housing and stops spinning. Result: the fuel pump fails without warning and the engine stalls or won't start — a stall at speed risks loss of power steering/brakes and a crash. This is the low-density-impeller Denso recall (NHTSA 23V-858, part of Honda's multi-million-unit Denso pump campaign), separate from the high-pressure-fuel-pump crack/fire recall. Honda dealers inspect and replace the defective pump module free.

What does P062F mean on Honda?▼
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. On Honda specifically, this code is documented across 1 model.
What causes P062F on Honda vehicles?▼
Common causes on Honda: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P062F on a Honda?▼
Repair costs vary widely depending on the root cause and specific Honda model.
Which Honda models have P062F documented?▼
Au7o has documented P062F on 1 Honda model: Civic.
