check engine light came on

[Deadeye_88]

i have a question. i just installed a smoke switch on my 2007 f-250 and my check engine light comes on whenever i turn the turbo off. i plugged in my livewire and i read the dtc codes and it said 3 codes. p0046, p1000, p0000. p1000 and p0000 are just testing incomplete and the p0046 is the vgt malfunction, which im turning off. is also it the turbo is boosting up whenever i turn the switch to off. what should i do?

[swalker332]

turn the switch off and clear the codes. do they come back? cuz the p0046 will come on when you use the switch of course cuz you just make in open in the wire, and the p1000 code come on when the vehicle hasnt finished completing its self tests. try turning the switch off and clearing the codes and see if you get the light again.

its goes out when you clear it. but when you turn the key off and the and then restart the truck and turn the switch bk off it comes on. i wont the light to stay off completely.

so basically i have to clear the check engine light every time i want to have fun. do anybody know why the turbo is boosting up. i got to like 10psi. it took a while but it evenually got there.

mine will stay off for a 5 to 7 second puff on someone. If I leave my switch off to long the light will come back on but i dont know how much time it takes for an interrupted circuit to turn on the engine light. I always leave my switch in the on position and only flip it off long enough to smoke a few seconds at a time. It may be that your having it off to much. I dont completely understand but drive with it in the normal position a while. It may have a lot of crap in the vanes if they were left open (i think) for to long or a possible bad connection leaving an open in the circuit. i think the key to keeping your engine light off is smoking in short bursts. I found the best smoke at slow speeds just creepin (15-20mph) along and keep your foot off the throttle to let the turbo slow down then I pull it into 3 flip my switch and lay into it. keeps it loaded down and wont let it downshift so a few seconds will work fine. Hope this helps
