P26FEExhaust Flow Control Valve A Control Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P26FE concerns the electrically driven exhaust flap A on models with selectable exhaust sound. The circuit is fine, but the flap does not reach the commanded position. Ford's OBD summaries 2020–2024 assign it to bank 1 and use two checks: the flap's smart driver reports a stuck valve over its PWM line, and a rationality test compares measured with commanded position, with a duration that depends on ambient conditions. Ford bulletins 17-2063 and 17-2217 (Focus RS 2016–2017) trace it to a valve freezing below 0 °C and fix it with new PCM software; 23-2132 (Mustang 2018–2023) blames a badly seated exhaust; 25-2144 (F-150 5.2 L, 2023–2025) requires PCM update and actuator alignment. Drivers see a lit MIL and a message that exhaust or drive mode is unavailable; bank 2 uses P2BFB.
- What you may notice
- Check engine light on
- Message that exhaust or drive mode is not available
- No audible change in exhaust sound between modes
- Likely causes
- LikelyFlap sticking from corrosion, soot or freezing moisture
- PossibleExhaust or actuator bracket not seated correctly
- PossibleActuator not aligned after replacement or outdated PCM software
- RareWorn or failed flap actuator
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
