P2676 Air Cleaner Inlet Control Circuit Low

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P2676 means the control line of the air cleaner inlet flap sits at too low a voltage for the state the controller has commanded. On a low-side driven solenoid this typically appears when the line is shorted to ground and the actuator is energised permanently; on other designs a shorted coil pulls the voltage down. Ford lists P2676 in its 2014 gasoline OBD code list as a continuous test with no MIL entry, so on those cars the code may sit in memory without a warning lamp. No public Ford text names the vehicles or the flap's job. CARB requires outputs that can change emissions to be checked for such faults. Expect the flap to stay in one position; drivability rarely changes. P2677 covers the opposite case.

Likely causes

Control wire chafed through and shorted to ground
Shorted coil in the inlet flap actuator
Water in the actuator connector

Symptoms

  • Code stored, often without warning lamp
  • Inlet flap stuck in one position
  • Possibly changed intake noise
