OBD-II Code

P2076

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.

Indicative cost (USD)

$80–$750

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.

P2076 sets when the ECU detects that the Intake Manifold Tuning Valve (IMTV / IMRC / SCV) position sensor on bank 1 or a single-bank engine is reading out of the expected range - the actuator commanded one position (open or closed) but the position feedback reports a value implausibly different from command.

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

P2076 sets when the ECU detects that the Intake Manifold Tuning Valve (IMTV / IMRC / SCV) position sensor on bank 1 or a single-bank engine is reading out of the expected range - the actuator commanded one position (open or closed) but the position feedback reports a value implausibly different from command. The intake manifold tuning system uses motor- or vacuum-actuated runner control to vary the effective intake-tract length for low-speed torque vs. high-RPM breathing; when the system can't confirm its commanded state, the ECU sets P2076 and typically defaults the valve to an open or limp position.

Cheapest-first ladder

  1. Inspect the IMRC actuator/linkage on the intake - broken plastic linkage arms, snapped return springs, or a stuck flap dominate the failure mode on engines past 100k miles.
  2. Read live data for IMRC commanded vs. actual position - a stuck-at-one-end actual position with command sweeping is your confirmation the actuator is mechanically jammed.
  3. DMM the IMRC position sensor (often a potentiometer-style sensor) - 5V reference, ground, and signal voltage should sweep proportionally with linkage movement; flat or stuck signal means sensor failure rather than mechanical bind. Expensive-misdiagnosis trap: full intake-manifold replacement when the fault is a $25 plastic linkage clip.

  • 2005-2011Ford F-150 / Expedition / Mustang with the 4.6L / 5.4L 3-valve Triton throws P2076 frequently from snapped IMRC linkage arms - the plastic arms fatigue and the runner flaps droop into the airstream, throwing both the position code and rough-idle complaints.
  • 2007-2014GM trucks with the 5.3L / 6.0L Vortec throw P2076 from a failed IMRC motor or stuck butterfly.
  • 2008-2013Audi / VW 2.0T (BPY, CCTA) throws P2076 from a failing intake-manifold flap motor (the swirl/tumble flap actuator) - VW TSB coverage exists for upgraded motor part numbers.
  • 2003-2010Mazda 3 / 6 / CX-7 throw P2076 from a stuck VAD (Variable Air Duct) actuator.
