P0E47Hybrid/EV Battery Pack Voltage Sense E Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- MIL and hybrid warning on
- Charging or regenerative braking restricted
- Electric drive limited or blocked
- Likely causes
- LikelySense lead of channel E chafed through and touching a higher potential
- PossibleBroken divider resistor or lost reference in the measuring circuit
- RareDamaged measuring input or software fault in the battery controller
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
