Even if it is under warranty, I would recommend you get a diagnostic scanner. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. I got a simple U480. The runner valve is essentially a second throttle body butterfly plate for the air intake system. However, it is scientific fact that air can move faster through smaller spaces versus larger spaces. What repairs can fix the P2017 code? For deeper diagnosis, and more technical information, Forscan is the best system available for Fords.
Need help with a P2017 code? How serious is the P2017 code? What causes the P2017 code? The intake manifold has many big ports which take a long time to fill up because of their large size. The faster the intake manifold can fill up with air, the faster the acceleration will be, and the more economic the air-fuel ratio. However, keep in mind that, with a Check Engine Light illumination, you can not legally pass inspection until the cause of the light is addressed. . Suspect no1 has to be the throttle valve. Have a chat with a couple of local garages you feel you can trust. To take advantage of that, there were electronically controlled flaps designed into some intake manifolds to help fill up the intake manifold with air faster and to get air into the combustion chamber faster.
I have found that when a garage that does not know what it is doing, or is not interested, does a job, it usually causes more problems in the long run. For example, if the the engine is increasing speed from a stopped position, the runner valve will slightly close the flaps in order for the air to enter the engine faster, which will in turn help the vehicle gain speed faster, but restrict fuel consumption. If not, I would advise to not take it in until the fault occurs again, and you have been able to confirm the codes yourself, and they are still there when it went to the garage. You may get information that is lost by the time it gets to a garage. Hello All Purchased a 2012 1.
YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine. The runner valve will open or close in order to allow the air to enter the engine faster or slower. At up to £100 just to read codes that may have self cleared, it is an expensive business. I have never heard of any cases in which it was serious or severely damaging. If code P2017, sets there may be an issue with the operation of the flaps in the engine, which are controlled by the runner valve. Reading the codes does no harm, and makes no difference.
When this plateau happens, the flaps will open up wider. They will hate it, of course! So the more information you can get, the better. This code will usually not be very serious. But it may not be worth a garage doing that. The valve may not need replacing, I would remove it and test it on the bench, it is just a motor and a simple feedback pot.
In this instance, Intake Air Flow Valve could be the throttle valve, or the adjacent by-pass valve if your engine has this. The flaps will open or close depending on the current needs of the engine. I am guessing that the codes have re-occurred after being cleared, at least the P02E9 one, and that you have done some research on the net to back up my opinion that it is throttle valve. Forscan is a really great system, but it needs using with care, the results are only as good as the software in the car, and that is sometimes far from perfect. Just do not clear them, unless you really need to for some reason, like you are 100s of miles away from the dealership.
One part that might match this on the Focus is the throttle valve or anti-shudder valve that is in the pipe from the intercooler to inlet manifold. . . . .
