Low Power- P0488 EGR Throttle Plate Codes
 

Ok so with age we are starting to see this code more and more and I figured it was common enough to do a video on just what it is all about. It has to do with the Egr throttle plate sticking in its bore and upon the sweep the pcm does it does no return to the full open position. In the video I show you exactly why it is flagging that dtc and how to replace the egr throttle plate with a few tips.
