P2071 on Chevrolet
Intake Manifold Tuning (IMT) Valve Stuck Closed
P2071 on Chevrolet vehicles indicates intake manifold tuning (imt) valve stuck closed. Au7o has documented this code across 1 Chevrolet model — most commonly on Cruze. This code means the engine computer detected that the intake manifold tuning (IMT) valve is stuck in the closed position. The IMT valve changes the effective intake manifold geometry to optimize airflow and torque across the RPM range. When stuck closed, the engine cannot achieve the intended airflow tuning, which may reduce power (especially at higher RPM) and trigger a check engine light. It is generally not an urgent safety issue but should be addressed for proper performance and emissions. Typical repair costs on Chevrolet range from $100 to $800, depending on the specific model and root cause.
Common Causes of P2071
- •Carbon buildup binding the IMT valve closed
- •Stuck or seized IMT valve actuator
- •Failed vacuum actuator or leaking/blocked vacuum line
- •Broken valve linkage
- •Faulty IMT valve position sensor
- •Wiring or connector fault to the IMT solenoid
P2071 on Chevrolet by Model
Chevrolet Cruze(1 issue)
- Intake Manifold Runner Control Failure (1.4T)2011-2016
The intake manifold on the 1.4T Cruze has variable-length intake runners controlled by an internal flap actuator. The actuator motor fails or the runner flaps stick due to carbon buildup and oil contamination (especially when the PCV valve cover has also failed). When the runners stick open or closed, the engine loses low-end torque, idles rough, and throws a check engine light. The plastic runner flap pivots can also break, sending debris into the intake port and potentially the cylinder.

What does P2071 mean on Chevrolet?▼
P2071 stands for "Intake Manifold Tuning (IMT) Valve Stuck Closed." This code means the engine computer detected that the intake manifold tuning (IMT) valve is stuck in the closed position. The IMT valve changes the effective intake manifold geometry to optimize airflow and torque across the RPM range. When stuck closed, the engine cannot achieve the intended airflow tuning, which may reduce power (especially at higher RPM) and trigger a check engine light. It is generally not an urgent safety issue but should be addressed for proper performance and emissions. On Chevrolet specifically, this code is documented across 1 model.
