Are you sure you have a MAP sensor? I looked your truck up and they only list a Mass Airflow sensor. If you have one, you usually don't have the other.
From similiar engines, I am guessing your temp sensor is dead center on the top front of the engine under the air duct. There may be two of them there. One for the dash guage, and one for the engine computer.

I do not have a map I have a maf I hit the wrong key. I did clean the maf today and it got a little better and then about 45 min later my check engine light came on and got the code p1151 which is h02s21 running lean could that have happened from cleaning the maf?

I could see that happening if the air ducting had a leak somewhere. The MAF tells the computer how much air is flowing into the engine. If there is air coming in somewhere else that the MAF doesn't know about, it could let too much air into the engine.
