P26EDEngine Sound Control B Circuit Low

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
P26ED concerns the second sound actuator and indicates a drive line pulled toward ground. A conductor rubbed bare on the exhaust bracket, a pinched loom or corrosion bridging the pins of a wet plug are the classic culprits, along with a shorted coil inside the actuator. No maker publishes this code or its limits; the A counterpart P26DC appears in Ford's 2014 code list, which is the closest reference. Where the second flap sits on the other exhaust branch, its wiring often takes a different route under the car than circuit A, so the A side being healthy says little about B. In everyday use the sound feature loses part of its effect, while engine power is not affected.
What you may notice
  • Check engine light
  • Second flap does not respond, sound only partly changes
Likely causes
  • LikelyInsulation of the actuator B wire worn through against metal
  • PossibleCorroded or wet connector at actuator B
  • PossibleShort circuit inside actuator B
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
