Use a multimeter to test the two wires in the IACV connector for voltage and ground.
Code 14 is generally produces idle problems. What are they?
Or is the CEL code actually 10 and 4? ...or 1 and 4? ...or 41? Post a video.

-i posted here because it is a mystery for me also.I was at service and they told me that it`s the error 14. Not 10 and 4 . (tonight i drive and car went well not errors,but during the day i think that error is ON because of the outside temperature)

When the engine is warmed up and the idle is high, remove the intake system. Then use your finger to cover the hole inside the throttle body leading to the FITV. Does the idle speed drop?
Next, do the same test for the hole inside the throttle body leading to the IACV.

Re: Problem Valve IAC D15B JDM EG8
Did you already clean the IACV? If so, test whether the 2 wires in the IACV connector have battery voltage and ground. Also, Ohm test the IACV itself.
If those are fine, next test the ECT sensor and the TPS.

Today I cleaned the IACV and it does the same as before. When I drive and I want to accelerate the car goes disscontinued .Even if I remove the IACV jake ,the car works jerky (when I push the throttle constant at 1500 rpm the car works the same as in the video that I showed you.If I want to keep speed between 1500 and 2500 rpm the speeds suddenly jumps over 2500 rpm).
