P2AB6Cold Start Intake Manifold Runner Control Stuck Closed Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2AB6 reports the runner flaps of bank 2 held in the closed position during the cold-start phase, against a command to open them. Like its siblings it exists only on engines that control each bank's runners separately and only becomes testable after a soak of six hours or more at ambient temperatures from -6.7 °C upward, as defined in CARB's cold-start rules. No manufacturer documents P2AB6 publicly. Ford's gasoline summary for 2020 to 2023 lists the everyday equivalent as P2007 and treats plates that miss the commanded position or overrun their travel as a functional fault. Because only one bank is restricted, the engine may run slightly unevenly between the banks until the flaps free up or the strategy ends. If P2AB5 is set as well, suspect a shared actuator supply. P2AB4 is the open-stuck case on this bank.
- What you may notice
- Check engine light on
- Slightly uneven running and reduced pull after a cold start
- Higher cold-start emissions
- Likely causes
- LikelyBank 2 flaps seized by deposits or ice
- PossibleBank 2 actuator or its control valve defective
- RareShared actuator supply or vacuum source weak (often with P2AB5)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
