What P0B60 means
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.
P0B60 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0B60
- MIL and hybrid or EV system warning
- Electric drive power limited or switched off
- Charging interrupted
Common causes of P0B60
- Most likelyChannel H sense lead shorted to ground or to the next lower tap
- PossibleFailed measuring input on the cell monitoring board
- Less likelyCell or block on channel H actually collapsed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0B60 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| B | Area: hybrid propulsion. |
| 60 | The exact fault in that area. |
What to do next
- Note P0B60 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 P0B60
What does P0B60 mean?
P0B60 means "Hybrid/EV Battery Voltage Sense H Circuit Low". P0B60 means channel H reports less voltage than any healthy cell or block could hold, so the measurement itself is suspect. It is a generic code, so it means the same on every make.
Is it safe to drive with P0B60?
Drive gently and only to a workshop. With P0B60 the car can go into limp mode (reduced power) to protect itself.
Will P0B60 fail an emissions test?
Yes, it can. P0B60 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 P0B60 to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0B60 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
