P2070 on Chevrolet
Intake Manifold Tuning (IMT) Valve Stuck Open
P2070 on Chevrolet vehicles indicates intake manifold tuning (imt) valve stuck open. 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 open position. The IMT valve adjusts the intake manifold's tuning to optimize airflow and torque at different engine speeds. When it is stuck open, the engine loses the intended airflow tuning, which can reduce low-end torque or overall performance and trigger a check engine light. It is not an immediate breakdown concern but should be repaired to restore drivability and emissions compliance. Typical repair costs on Chevrolet range from $100 to $800, depending on the specific model and root cause.
Common Causes of P2070
- •Carbon buildup jamming the IMT valve open
- •Stuck or seized IMT valve actuator
- •Failed vacuum actuator or leaking vacuum line
- •Broken valve linkage
- •Faulty IMT valve position sensor
- •Wiring or connector fault to the IMT solenoid
P2070 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 P2070 mean on Chevrolet?▼
P2070 stands for "Intake Manifold Tuning (IMT) Valve Stuck Open." This code means the engine computer detected that the intake manifold tuning (IMT) valve is stuck in the open position. The IMT valve adjusts the intake manifold's tuning to optimize airflow and torque at different engine speeds. When it is stuck open, the engine loses the intended airflow tuning, which can reduce low-end torque or overall performance and trigger a check engine light. It is not an immediate breakdown concern but should be repaired to restore drivability and emissions compliance. On Chevrolet specifically, this code is documented across 1 model.
