Ok, I got my fog lights yesterday and installed them and the wired at the front but i now need to order the switch, not a prob. But when i got in the truck today and stated i get two codes coming up and this is the first time i have had a code. So i got my OBD II scanner and it says ( P0072 & Poo73 )codes. and says Ambient temperture sensor circuit low and high voltage....so what does this mean...what is it i am lost...
