P2675 Air Cleaner Inlet Control Circuit/Open

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

Some engines can change where the air cleaner draws its air, for example switching between a cold inlet at the front and a second opening in the engine bay, with a flap or valve moved by a solenoid or small motor. P2675 is the open or general circuit fault of this control: the module driving the flap detects that its output line carries no current or reports a fault it cannot classify further. No manufacturer documents P2675 publicly. Ford's 2014 gasoline code list contains only the low and high variants P2676 and P2677, both as continuous tests without MIL, which suggests the open case is treated inside those codes there. CARB demands circuit checks on outputs that can influence emissions. The flap then stays wherever it stopped.

Likely causes

Connector at the inlet flap actuator loose or unplugged, often after air filter service
Broken wire in the actuator circuit
Open coil or motor winding in the flap actuator

Symptoms

  • Warning light or stored code, often without MIL
  • Inlet flap no longer switches
  • Usually no noticeable change in driving
