That sensor is integrated into the MAF sensor, sneak a temp probe into the intake elbow, or point an IR thermometer on it to confirm the performance of the sensor. When you've got sensors reading stuff that makes no sense, it's easiest to start by finding out if it's true or not.

If the sensor is telling the truth, test hood open, hood closed, while driving. If the sensor and it's circuit aren't faulty then the only way to read that high is to be roasting the air filter. Check that your air filter housing is correctly connected to the intake snorkel which grabs air inside the front bumper, if it's disconnected you'll be sucking in toasty air from above the radiator, and idling without airflow and subject to the rising heat from the exhaust, that can get properly warm. Also confirm that the air filter housing is properly closed, these types of air boxes are easy to leave disengaged at the bottom, that would leave a nice big gap at the bottom for it to grab hot air.
