P0AB7Engine Mount B Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- P0AB7 means the engine controller sees the control line of active engine mount B pulled too low, the usual signature of a short to ground or an actuator coil with too little resistance. Ford's 2020-23 gasoline OBD summary lists it among the active-mount checks for bank 2: the output driver flags the fault continuously and the PCM matures it within roughly 5 seconds. Honda describes the code on the 2008 Pilot as a low-current fault in the rear mount actuator circuit. P0AB6 covers the open circuit, P0AB8 the high side, and P0A15 the same fault on mount A. The driver usually feels more engine shake at idle; drivability is otherwise unaffected.
