P0ABDHybrid/EV Battery Pack Voltage Sense A 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
- The counterpart to P0ABC: the pack voltage reading is above the highest value the battery could physically reach, which suggests an open reference, a failed divider or a damaged input rather than real overcharging. GM's 2016 and 2019 hybrid tables set P0ABD above 392 V, again with 8 failed samples out of 10 at 25 ms intervals and Type A, so the MIL comes on immediately. For the smaller pack in its 2013 table the limit is 190.1 V, with 7 of 10 samples and Type B. Range and plausibility problems are reported by P0ABB, the low limit by P0ABC. The vehicle typically limits or blocks electric operation until the fault is cleared.
- What you may notice
- Hybrid system or check engine warning on
- Electric drive limited or unavailable

- PossibleVoltage divider component failed in the battery controller
- RareBattery controller measurement input defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
