check engine light popped on about a week ago. Plugged in my OBD2 scanner and came up with P0069. Took it to the dealer and they said I needed a new speed sensor and MAF sensor. I said no to the MAF. Came home and cleaned the MAF. Reset the light and drove it for an hour. No light! When I went to start the truck back up, it threw the check engine light. Same code. Any ideas as to where the IAT sensor bank 2 is?
