    I have a 2003 Tacoma V6

    PO113 Intake Air Temperature Circuit High Input



    What does this all mean? Can someone help me trouble shoot these problems, so I can get the truck to run right.

    v4 or v6?

    Anyways, check your airbox. (where the air filter is) Make sure the MAF sensor is still plugged in. you may have to replace the sensor (located on the tube)

    Ok, do you use an oiled air filter or cold air intake or a K&N anything.


    Also a good bet would to be go to autozone and pick up some maf cleaner and clean your mass airflow sensor. It may cure all the problems

    My MAF was stolen along with airbox. I got a junk yard MAF, but no airbox. Was just running a metal screen over MAF tube.

    MAF cleaner sounds like a good idea

    I was able to clean the MAF and Throttle Body.

    The only code its throwing now is

    PO113 Intake Air Temperature Circuit High Input


    Is the AIT another sensor?

    then your MAF is toast. gotta replace that. might as well get an airbox to protect it
