Craig chung Posted May 9 Report Share Posted May 9 I have bmw e34 engine thats turbo, I parked the car for 5 min then after starting the car,it started to idle rough plus it doesn't hold idle, I have to give it gas in order hold to idle, I limp the car home, after plugging my laptop to see if anything pops up I notice it has 6 codes 63,47,44,14,67,64 I'm just wondering if my tps sensor or my iat just took a crap all off a sudden Quote Link to comment Share on other sites More sharing options...
essb00 Posted May 9 Report Share Posted May 9 Looks like some wiring(s) of your sensor's +5V have touched the ground. You'll be needing to check the wiring of all your analog inputs using the +5V supply. Quote Link to comment Share on other sites More sharing options...
Craig chung Posted May 10 Author Report Share Posted May 10 thanks I was just going through it and I believe 5v analog is causing all this hiccups Quote Link to comment Share on other sites More sharing options...
