P0E64 code meaning
Battery Charger A Enable Circuit Range/Performance
What P0E64 means
P0E64 covers an enable line that is electrically intact while the charger still does not respond as it should. Ford documents it in its 2019 hybrid OBD summary, there titled Battery Charger Enable Circuit Range/Performance: the check runs once the charger is in its ready state and the charge wake-up signal Chrg_Wkup has gone high, and it fails when the battery energy control module still reports not ready after 30 seconds. The same monitor group checks the charger's output power against the expected value under P0D20. A BECM that does not wake, a slow start-up of either module or software disagreement between charger and BECM can therefore set P0E64 without any wiring fault. For plug-in hybrids, CARB demands detection of such charging failures. Open, low and high circuit faults are P0E61 to P0E63.
P0E64 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E64
- Charging does not start although the cable is connected
- Charging system warning or charge port light shows a fault
Common causes of P0E64
- PossibleCharger and BECM do not complete start-up within 30 s (software or wake-up timing)
- PossibleBattery energy control module not waking or not reporting ready
- Less likelyHigh resistance on the wake-up line producing a marginal level
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E64 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 64 | The exact fault in that area. |
What to do next
- Note P0E64 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0E64
What does P0E64 mean?
P0E64 means "Battery Charger A Enable Circuit Range/Performance". P0E64 covers an enable line that is electrically intact while the charger still does not respond as it should. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E64?
P0E64 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E64 fail an emissions test?
P0E64 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0E64 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0E64 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
