What P2005 means
P2005 is the bank 2 version of the stuck-open check, so it only exists on V and boxer engines with a flap set per cylinder bank. The ECM has commanded the flaps on bank 2 closed, but the position feedback says they stayed open. Ford runs it on vacuum-operated V engines once coolant is above 40 °F and logs it after four failed events; on the 2017–2019 Super Duty 6.2L Ford found cracked vacuum hoses on the manifold and supplies the hoses alone instead of a new manifold. Audi links P2005 on the 4.0 TFSI (A8, S6, S7, RS 6, RS 7) to moisture in the flap potentiometer and fits a repair kit on both banks; the engine may be held to 4,000 rpm. Subaru names it on Forester Turbo and WRX, where EGR condensate corrodes the tumble valve shaft. Open flaps mostly cost low-speed torque and smooth idle.
P2005 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2005
- Malfunction indicator lamp on
- Less pulling power at low engine speed
- Rpm limit on some Audi V8 engines
Common causes of P2005
- Most likelyCracked or loose vacuum hose to the bank 2 flap actuator
- PossibleMoisture in the flap potentiometer giving a false position (Audi 4.0 TFSI)
- PossibleFlap shaft corroded or seized in the open position
- Less likelyTorn diaphragm in the vacuum actuator
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2005 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. |
| 05 | The exact fault in that area. |
What to do next
- Note P2005 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 P2005
What does P2005 mean?
P2005 means "Intake Manifold Runner Control Stuck Open (Bank 2)". P2005 is the bank 2 version of the stuck-open check, so it only exists on V and boxer engines with a flap set per cylinder bank. It is a generic code, so it means the same on every make.
Is it safe to drive with P2005?
Drive gently and only to a workshop. With P2005 the car can go into limp mode (reduced power) to protect itself.
Will P2005 fail an emissions test?
Yes, it can. P2005 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 P2005 to fix?
Difficulty: medium. A typical repair takes 0.3 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2005 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
