P0A14Engine Mount A Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- Some vehicles use switchable or active engine mounts that the powertrain or a mount control unit changes between soft and firm, or drives with an actuator against vibration. P0A14 reports an open or undefined fault in the control circuit of mount A. Ford lists it in its 2020 to 2023 gasoline OBD summary as the active mount circuit check: the low-side driver reports the fault and it matures after about 5 seconds; mount B uses P0AB6 to P0AB8. Honda's active control engine mounts, for example on the 2008 Pilot V6, use P0A14 for the front mount actuator and P0AB6 for the rear. P0A15 and P0A16 cover low and high faults. The car stays drivable, but vibration may increase.
