P26EEEngine Sound Control B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- For the second sound actuator, P26EE signals a drive circuit carrying more voltage than expected, i.e. a short to battery positive or a feed coming back from a damaged actuator. Because the line is then powered from elsewhere, flap B may hold its position no matter what the driver selects. P26EE is not published by any maker; for orientation there are only the A codes in Ford's 2014 list and the exhaust valve driver checks in Ford's later summaries, which report output faults through a smart driver. When diagnosing, compare the B line with the unswitched supply wires running beside it and test the actuator off the car. Engine behaviour and emissions in normal driving are generally unchanged.
- What you may notice
- Check engine light
- Second flap stuck in one position
- Likely causes
- LikelyActuator B wire in contact with a positive supply wire
- PossibleDamaged actuator B feeding voltage back
- RareFaulty output stage for circuit B in the module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
