There are several possible reasons for this fault to occur, however, the swirl flaps themselves cause the most concern. The reason is that they are inside the intake manifold. Should they be the problem and fail, parts will fall and be ingested into the engine. That is a recipe for a bad day.

Look at all the freeze framed data to see what conditions the vehicle was under when the code was set.

Commonly the intake manifold runners and intake manifold runner control solenoid will exhibit similar symptoms and one may be replaced when the other is causing the fault.

If the turbo housing has cracked, or the internal seals have blown, oil will start to leak into your exhaust system. As this burns off, it produces a distinctive blue/grey smoke, which will probably become more apparent as the engine revs increase just following an idle situation.

Use a multimeter to check for continuity in the wiring.

If you notice that your turbocharged vehicle is accelerating more slowly than usual, or isn’t capable of reaching the speeds it once could, this may be a sign that your turbo is failing.

By creating a swirling of the intake air, the pulsations created by the intake valve opening and closing is nullified and the quality of the air fuel mixture is improved. Low end torque is improved and the formation of Nox is reduced as well with the use of these flaps.

Corrie19994 months ago

The code is referring to a fault that has occurred in a set of air control flaps inside the intake manifold. These flaps are designed to create a specified amount of turbulence within the manifold that is transformed into a 'swirling' effect.

This code is similar to P2005, P2006, P2007, P2009, P2010 and P2015.

Hook up the scan tool and pull any codes that are stored in the ECU.

Fionas_Boy4 months ago

The electronic control module (ECM) controls the position of the swirl flaps with the use of an intake manifold runner control solenoid valve after referencing the signals from the mass air flow sensor (MAF) and the barometric pressure sensor. When the ECM determines where to position the swirl flaps, it uses 'pulse width modulation' to control the intake runner control solenoid.

Note: Be sure to check for TSBs also, as there is a known TSB for certain Audi vehicles where the fix is to reprogram the ECM.

An advanced level scan tool that does more than just read codes is required for this code. Technicians use these scan tools to view live data such as voltage and solenoid operation.

I replaced both solenoids with a Engine Air Shutoff Control, Ford part no 1357313, cost £61.78

Pete_W4 months ago

I had exactly the same symptoms as Coxie. In my case the problem turned out to be the solenoids located top right of the engine which control (using manifold vacuum) the airflow in the inlet manifold. As there are two identical solenoids, I switched them over to see if the fault changed, and it actually went away so I presume one of the valves is not monitored. As least my intermittent P2008 fault had gone.

On most modern cars, the computer diagnostics will pick up turbo faults and the check engine light will come on. Of course, the check engine light doesn’t just cover turbo failure, and you will need to do some further checks to see what kind of engine problem you have.

Bri19874 months ago

P2008 means that the intake manifold runner circuit has an open electrical connection bank 1. The ECU tries to control the the angle of the intake manifold runner flappers and when it cannot control this circuit sets a Check Engine Light.

The P2008 can be difficult to diagnose if the proper steps are not followed or are not completed in the correct order.

There are several ways that your vehicle will let you know that its turbo is in need of maintenance or repairs:

Bri19874 months ago

Often, a failing turbocharger will make a loud, distinctive noise when under boost. If you start to hear this noise from your engine, it’s definitely time to have it checked out!

R2_Amazeballs4 months ago

If you notice any of the warning signs, then get your turbo checked as soon as possible. Your turbocharger is not going to repair itself, and the longer you leave it, the worse (and more expensive) the problem will get!

Col Minessota4 months ago

A service manual for the vehicle and a scan tool will be necessary to diagnose and effect a conclusive repair. The ECM uses pulse width modulation to vary the position of the swirl flaps with the intake runner solenoid.

Volvo V40 intake manifold fault

Once it's been determined that they are not the problem, the stress level drops. Certain vehicles were notorious for swirl flap failure where the screws retaining the flaps would fall out if the flap failed. The screws entered the engines and caused major engine damage. This engine code is identical to P2011 but that code is for Bank 2, and this DTC is for Bank 1. Bank 1 is the side of the engine that contains cylinder #1.

FordOwner4 months ago

Some turbocharged vehicles are fitted with a boost gauge, which lets you how much boost your turbo is producing (you can also fit one to your car if desired). If your boost gauge isn’t going up as much as it used to, then there is a good chance your turbo is in need of repair.

The P2008 code is a general OBD2 diagnostic trouble code referencing the Intake manifold runner control circuit.

Mary4 months ago

Perform a visual inspection, taking a close look at the vacuum lines and wiring under the hood

Corrie19994 months ago

The P2008 code can have a serious side effect if left unattended for too long. The intake manifold runner flaps can break off and be sucked into the engine. This can cause extensive engine damage.

FordOwner4 months ago

Use the scan tool to monitor solenoid operation while the engine is running and watch for changes.

Hi I have a 1.8 Ford C-MAX on a 53 plate, which has a intermitant fault code P2008 Intake Manifold runner control circuit / open bank 1. I have had this reset twice but it keeps coming back, and when the Engine warning light come on the car becomes slugish and will not pull away properly. Can anyone tell me what is a Intake Manifold runner control circuit and if I can be change without going to a garage and how much?

FordOwner4 months ago

I had the same problem with my Ford Focus 2.0 2009 last two years, but no one could solve my problem. I spend quite lot of money on repairs. Finally I tried to do it myself. And after half an hour (I switched solenoids) enigine works as a new. I am going to buy new one in the future, but finally I found the problem!

The OBD trouble code P2008 is a generic powertrain code, which means that is applies to all 1996-newer vehicles (Ford, VW, Audi, GM, etc.). Although generic, the engines differ between brands and may have slightly different causes for this code. Always refer to a vehicle specific service manual for the proper diagnostic sequence and reference numbers.

Mary4 months ago

Take the vehicle on a road test to confirm the symptoms.

Col Minessota4 months ago

In some cases an intake cleaner can be used to help free any stuck manifold runner flaps. These cleaners dissolve some of the carbon deposits and free the flapper valve.

Corrie19994 months ago

This is a 'soft' code, meaning the check engine light may blink on and off only when the ECM sees the fault. If the fault corrects itself the light will go off. Hard codes will remain once observed until erased.

Install a hand vacuum pump to check for intake manifold runner flapper valve operation.
