P0B60Hybrid/EV Battery Voltage Sense H Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0B60 means channel H reports less voltage than any healthy cell or block could hold, so the measurement itself is suspect. GM publishes three variants. Lithium-ion packs with a battery energy control module (2016 and 2019 tables) trip at 0.2 V or less for 1.4 s inside a 2 s window, Type A, provided no open-line, communication or balancing fault is already stored. The BAS Plus mild hybrid in table 13OBDG05C uses a cell sense line threshold of 1.4 V and needs 7 failures out of 10, Type B. The 2012 two-mode trucks compare blocks 8 and 9, both under 2 V in 15 of 20 samples, Type B. Typical culprits are a sense lead shorted to ground or a failed input on the monitoring board.
- What you may notice
- MIL and hybrid or EV system warning
- Electric drive power limited or switched off
- Charging interrupted
- Likely causes
- LikelyChannel H sense lead shorted to ground or to the next lower tap
- PossibleFailed measuring input on the cell monitoring board
- RareCell or block on channel H actually collapsed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
