P062F

Internal Control Module EEPROM Error

Q: Is it safe to drive with P062F?

Be cautious. The module reporting a long-term memory error can run erratically and may not restart reliably. Have it diagnosed before depending on the vehicle.

Q: Can I just clear P062F?

It may clear briefly, but if the battery/grounds are poor or the module's memory is failing it returns. Sort out the power supply first, then reassess the ECM.

ECM / control module Generic OBD-II High

What it means

P062F means the engine control module has detected a fault in its EEPROM — the long-term memory where it stores learned values and settings. Because the ECM relies on this data to run the engine, the fault can cause driveability problems or, in some cases, a hard-start or no-start. It's often triggered by a weak battery or poor power/ground connections, so check those before condemning the module.

High

Can I keep driving? Drive cautiously — a module memory fault can affect running and, in some cases, cause a hard-start or no-start; get it diagnosed before relying on the car.

Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

Common symptoms

What you'll notice

Check-engine light on
Driveability problems or reduced power
Lost adaptations/learned settings (rough idle after clearing)
Hard starting or, in some cases, a no-start

Common causes

Most likely first

Low battery voltage or a weak battery corrupting stored memoryLikely
Poor ECM power or ground connectionsCommon
Corrosion or moisture in the ECM connectorsCommon
Internal EEPROM (long-term memory) fault in the moduleLess often
Interrupted or failed reprogrammingLess often

How to diagnose & fix

Work through it in order

Test the battery and charging system, and clean/tighten the battery terminals — low voltage is a common trigger.
Inspect and clean the ECM power and ground connections and connectors.
Clear the code and see whether it returns after a few drive cycles.
Check for a manufacturer reflash/software update for the module.
If it persists with good power and grounds, the ECM likely needs reprogramming or replacement.
