What P201E means
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.
P201E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P201E
- Malfunction indicator lamp on
- Little or no change in drivability
Common causes of P201E
- Most likelyElectronics inside the bank 2 actuator failed
- PossibleBank 2 flaps binding and overloading the actuator
- Less likelyMoisture inside the actuator housing
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P201E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 1E | The exact fault in that area. |
What to do next
- Note P201E and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P201E
What does P201E mean?
P201E means "Intake Manifold Runner Control Actuator Internal Performance (Bank 2)". P201E says the electronic flap actuator serving bank 2 has detected or caused an internal malfunction; the wires to it are not the issue. It is a generic code, so it means the same on every make.
Is it safe to drive with P201E?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P201E fail an emissions test?
Yes, it can. P201E is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P201E to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P201E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
