OBD-II Code

P2079

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)

$90–$650

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

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.

P2079 is the bank-2 intake-manifold tuning valve position sensor 'circuit high' fault - the position-sensor signal voltage has risen above the upper electrical threshold, typically above 4.8V on a 5V-referenced sensor. The failure modes are mirror-opposite of P2078: a short to the 5V reference or to battery voltage, or a sensor whose internal wiper has lost ground reference and floats high.

Cheapest-first ladder

Disconnect the sensor and read the signal pin voltage KOEO - stuck-high with the sensor unplugged confirms the harness is shorted to the 5V reference or to switched battery somewhere between the sensor and the ECU; if it falls to floating with the sensor unplugged, the sensor itself is the failure.
Inspect the connector for pushed-back terminals - a 5V reference pin contacting the signal pin in a corroded connector produces exactly this code, and a clean-and-reseat fixes it.
Check sensor ground continuity to chassis with the harness loaded - a missing ground floats the signal reference high and triggers high-circuit codes that look identical to a shorted-to-power harness. The DMM check sequence runs about 15 minutes and isolates harness-vs-sensor before any parts are ordered.

2008-2014Audi / VW 3.6L VR6 FSI throws P2079 from the same intake-flap motor assembly as P2078 - the sensor element on the bank-2 side is the common-failure component.
2005-2010Mercedes-Benz M272 V6 throws P2079 alongside P2078 on alternating drive cycles as the intake-manifold runner-position sensor degrades.
2007-2012Cadillac CTS / SRX with the 3.6L LLT throws P2079 from a chafed bank-2 IMRC sensor wire at the harness clip behind the cylinder head.
2009-2013Hyundai Genesis Coupe 3.8L throws P2079 from sensor connector corrosion after road-salt exposure.
