I keep having this one code returning and I don't know what to make of it.<p>5-1-4 in socket A2.<p>In my Haynes manual, it's read as "Engine cooling fan faulty at half speed".<p>What could it be?<p>I also got a new one, 4-1-4 in socket A2<p>"Turbo boost presure too high"<p>I didn't adjust anything and the car is stock except the K&N air charger. Tune up done, tranny flush, feul filter replaced, and oil change.<p>I'm stumped. In addition to this, my shifting is still being done at 5000 rpms under WOT. Gonna clean the throttle body one day and see if the TPS sensor is bad.<br>
