P062F on Honda by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Engine stalls while driving with no warning
- Hard start or extended cranking, especially when hot
- No-start condition
- Whining or no sound from fuel pump on key-on
- Check-engine light with low fuel-pressure codes
How to Fix
Check the VIN against recall 23V-858 and have the dealer replace the in-tank fuel pump module free under recall. If out of recall scope but symptomatic, replace the fuel pump module with the updated Denso part. Don't ignore long crank / stall events — failure is sudden.

Frequently asked questions
What does P062F mean on a 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 it is documented across 1 model: Civic.
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 on a Honda?
Repair costs vary widely with the root cause and Honda model; each issue on this page carries its own estimate where one is published.
