I tried unplugging my Boost sensor (map sensor) after reading it would make for some good smoke. I was going to do a smoke switch but figured I would try that to see if it did anything before putting in the switch and having not work. I figured if I set a code I would just clean it out with my Hypertech Hyperpac. Truck ran bad and set a code. I scanned and found 2 codes. The first was low/no boost signal (duh!) and 1693. I found that one means it set a code in both PCM and ECM. I cleared the first code but the 1693 keeps showing up. So now I found out my programmer doesn't clear the PCM. I key on/key off and find codes 0500 and 1694, I don't know how long those codes have been there because I just found out that you can key/ key off these trucks ( I thought that only worked on older stuff). Do these codes affect the way the truck runs and fuel mileage? It seems to me my truck runs best and mileage is best when no codes show in the ECM. How do I get rid /fix them. The truck seems to run ok right now but I haven't driven much yet.Thanks
