What P0E47 means
P0E47 means pack voltage measurement E reports more voltage than the pack can reach even when fully charged. A sense lead touching a higher potential, a broken divider resistor or a damaged input of the measuring chip are the usual explanations; real overcharging is unlikely when only one channel shows it. P0E47 is not documented by any manufacturer in public. The 2013 GM two-mode hybrid pickups and SUVs test the analogous channel A against 430 V (P0ABD), using the same 300-of-400 counter at 10 ms and running the test only while the 12 V network sits between 9 and 18 V. CARB requires battery voltage sensors to be tested against plausible limits. Low and plausibility faults of channel E are P0E46 and P0E45. Expect a warning and restricted electric drive.
P0E47 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E47
- MIL and hybrid warning on
- Charging or regenerative braking restricted
- Electric drive limited or blocked
Common causes of P0E47
- Most likelySense lead of channel E chafed through and touching a higher potential
- PossibleBroken divider resistor or lost reference in the measuring circuit
- Less likelyDamaged measuring input or software fault in the battery controller
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E47 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 47 | The exact fault in that area. |
What to do next
- Note P0E47 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 P0E47
What does P0E47 mean?
P0E47 means "Hybrid/EV Battery Pack Voltage Sense E Circuit High". P0E47 means pack voltage measurement E reports more voltage than the pack can reach even when fully charged. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E47?
Drive gently and only to a workshop. With P0E47 the car can go into limp mode (reduced power) to protect itself.
Will P0E47 fail an emissions test?
Yes, it can. P0E47 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0E47 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0E47 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
