P201EIntake Manifold Runner Control Actuator Internal Performance (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P201E says the electronic flap actuator serving bank 2 has detected or caused an internal malfunction; the wires to it are not the issue. No manufacturer documents P201E publicly, and only engines with a separate smart actuator per bank can set it. On bank 1 GM lists the matching code P201D for its 2017–2018 diesels inside the group of faults that disable swirl control, but without its own thresholds, so even there the actuator decides what counts as internal. CARB asks for a functional check of every valve or flap system that alters charge motion. If P201E appears together with low supply (P201C) or circuit codes for bank 2, those come first; on its own it usually means the actuator, or a manifold with built-in actuator, must be replaced. Expect the bank 2 flaps to stay parked until the fault is gone.
- What you may notice
- Malfunction indicator lamp on
- Little or no change in drivability
- Likely causes
- LikelyElectronics inside the bank 2 actuator failed
- PossibleBank 2 flaps binding and overloading the actuator
- RareMoisture inside the actuator housing
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
