P0E64Battery Charger A Enable Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- 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.
- What you may notice
- Charging does not start although the cable is connected
- Charging system warning or charge port light shows a fault
- Likely causes
- 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
- RareHigh resistance on the wake-up line producing a marginal level
