P2071 code meaning
Intake Manifold Tuning (IMT) Valve Stuck Closed (Bank 1)
Powertrain system Generic code P20xx codes Check engine light
What P2071 means
Counterpart to P2070: the bank 1 tuning valve receives an open command, but the position feedback keeps showing it shut. In GM's 2006 and 2007 tables the check simply compares commanded and actual flap position under load between 1000 and 3600 rpm, Type B. From 2015 on (also engine LWE in 18OBDG03A) GM requires that the open stop is reached within 5 s; 320 failed out of 400 samples set the code, and it stays blocked while P0660 to P0662 or the sensor codes P2077/P2078 are active. GM's 2023/2024 tables describe P2071 as stuck open, so on those vehicles the meaning of P2070/P2071 should be checked against the service data. Ford lists the code without MIL. Expect lost power at high rpm; bank 2 uses P206F.
P2071 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2071
- Lack of power at high engine speed
- Check engine light (GM Type B, Ford without MIL)
- Engine otherwise runs normally
Common causes of P2071
- Most likelyFlap seized shut by deposits or corroded shaft bushings
- PossibleActuator defective, no longer turns the flap against its return spring
- Less likelyWeak supply to the actuator from a corroded connector or relay contact
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2071 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. |
| 71 | The exact fault in that area. |
What to do next
- Note P2071 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 P2071
What does P2071 mean?
P2071 means "Intake Manifold Tuning (IMT) Valve Stuck Closed (Bank 1)". Counterpart to P2070: the bank 1 tuning valve receives an open command, but the position feedback keeps showing it shut. It is a generic code, so it means the same on every make.
Is it safe to drive with P2071?
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 P2071 fail an emissions test?
Yes, it can. P2071 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 P2071 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2071 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.
