OBD-II Code
P2070
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P2070 means the Intake Manifold Tuning Valve (IMTV, also called IMRC on Ford or VIS on some Hondas) is stuck in the OPEN position — the long-runner/short-runner flap that's supposed to swing closed at low RPM to boost low-end torque is frozen in the high-RPM position.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P2070 means the Intake Manifold Tuning Valve (IMTV, also called IMRC on Ford or VIS on some Hondas) is stuck in the OPEN position — the long-runner/short-runner flap that's supposed to swing closed at low RPM to boost low-end torque is frozen in the high-RPM position. You lose low-end grunt, fuel economy dips, and the ECU sets the code when commanded position and feedback position disagree by more than the threshold (typically 10-15 degrees) for more than a few seconds.
Cheapest-first ladder
- pull the IMTV electrical connector and look for oil/coolant contamination (a leaking PCV or coolant crossover dumps gunk into the connector and seizes the stepper motor); clean the throttle body and intake plenum and try to free the flap mechanically by hand with the engine off.
- Scan live data for IMRC stepper-motor current — a healthy actuator pulls 0.3-1.5A when commanded; pinned at 0A means open circuit (broken wire or burned-out coil), pinned above 2A means the flap is mechanically bound and the motor is stalling.
- Verify 5V reference and ground at the connector before condemning the actuator.
- Expensive-misdiagnosis caveat: techs frequently replace the whole intake manifold ($400-900) when the actual failure is the $40-120 stepper motor or the linkage clip that holds the flap shaft — pull the actuator off and watch the flap move by hand before quoting a manifold.

- 2005-2012Ford Escape/Fusion/Edge with the 3.0L Duratec V6 is the most common P2070 ticket in North American shops — the IMRC actuator on the rear of the intake collects oil mist from the PCV system and the plastic linkage arm cracks; Ford sells the actuator separately from the manifold but the labor to reach it is 1.5-2.5 hr.
- 2008-2015GM 3.6L LFX/LLT (Camaro, CTS, Traverse, Acadia) throws P2070 when the intake manifold's plastic runner flap bushing wears and the flap drops off its pivot — GM revised the manifold mid-cycle but the original part is still in the field.
- 2011-2015Hyundai Sonata/Optima with the Theta II 2.4L GDI throws P2070 from carbon buildup binding the VIS flap.
- 2003-2013Mazda3/6 with the MZR 2.0/2.3L commonly throws P2070 from a stuck VAD/VTCS flap.
- 2006-2011Honda Civic/CR-V with the K20/K24 throws P2070 when the IMRC vacuum solenoid (on engines that use vacuum instead of an electric actuator) cracks its diaphragm.
Estimated repair$120 to $950.
