P0A15Engine Mount A Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- How the car detects it
- The control circuit of switchable or active engine mount A shows a voltage or current below the expected level, which usually points to a short to ground on the line or inside the actuator. Ford uses P0A15 in its 2020 to 2023 gasoline OBD summary for the active mounts: the low-level driver reports the fault and the PCM matures it after about 5 seconds; the partner mount B has P0AB7. Honda's active control engine mount system on the 2008 Pilot V6 assigns P0A15 to the front mount actuator and P0AB7 to the rear. Ford engineers describe these mounts as switched between a damping and a stiffening mode, so a stuck mount is felt as vibration. The open circuit is P0A14, the high fault P0A16.
