P2070Fuel & Air Metering

Intake Manifold Tuning Valve Stuck Open

P2070 means the intake manifold tuning (IMT) valve is stuck in the open position. This valve changes the effective intake runner length for better torque, and the ECM detected it is not moving as commanded. Causes include a stuck valve, a failed actuator, or a vacuum or wiring fault.

🚗 Yes, but expect some loss of low-speed torque until repaired.
