P0E62 code meaning
Battery Charger A Enable Circuit Low
What P0E62 means
P0E62 reports that the enable line of on-board charger A is held at a lower level than its commanded state allows, typically by a short to ground. If the module drives the line high to permit charging, the charger never sees the request. Should the line instead carry a low-active signal, a grounded wire could leave the charger permitted at all times, which is why manufacturers separate low from high. No manufacturer documents P0E62 publicly. GM's 2016 Volt and 2019 hybrid tables cover only the generic enable fault P0E61, using a hardware fault flag at 10.2 V or more, 30 failures in 40 samples and Type B. CARB requires plug-in hybrids to catch charger faults that prevent charging. A shorted enable wire can also overload the driver stage in the commanding module.
P0E62 at a glance
- Check engine lightUsually not

- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E62
- Charging does not start when plugged in
- Charging system warning
Common causes of P0E62
- Most likelyEnable wire chafed and shorted to ground
- PossibleEnable input of the charger shorted internally
- Less likelyDriver stage in the commanding module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E62 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 62 | The exact fault in that area. |
What to do next
- Note P0E62 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 P0E62
What does P0E62 mean?
P0E62 means "Battery Charger A Enable Circuit Low". P0E62 reports that the enable line of on-board charger A is held at a lower level than its commanded state allows, typically by a short to ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E62?
P0E62 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E62 fail an emissions test?
P0E62 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 P0E62 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0E62 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
