Air Intake Sensor that is located on the air filter box
If I connect this sensor my car will not start, If I disconnect this sensor my car starts but it will not go faster than 45 miles per hour. Can some one tell me how to fix this problem? Do I have to change this sensor?

Intake Air Temperature (IAT) sensor and Manifold Absolute Pressure (MAP) sensor are combined into a single assembly which is called Mass Air Flow (MAF) sensor. This MAF sensor is located on the air filter box near air filter hose, and is connected with a five wire connector. You cannot replace the IAT sensor alone. Instead a MAF sensor is replaced altogether.
P0111 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Range/Performance Problem. It is very likely the sensor got disconnected during some service work like replacing the engines air filter. Other causes- Dirty air filter - Intake air temperature (IAT) sensor harness is open or shorted - Intake air temperature (IAT) sensor electrical circuit poor connection - Faulty intake air temperature sensor
The Sentra is known to blow mass airflow sensors. If you bought an
aftermarket sensor and it says to reprogram the computer you are pretty
much out of luck. If it were me I would read the instructions again as
it probably means that you have to disconnect the battery for five
minutes and let the computer learn the new mass airflow sensor.
The mass airflow sensor, or MAF sensor, measures the
amount of air flowing into the engine through the air intake. The sensor
on your Nissan Sentra is located in the air intake tubing that runs
from the filter to the fuel injection system. If your Sentra is idling
rough, has problems starting and frequently stalls during normal
driving, it is likely that the MAF sensor is failing and needs to be

New MAF sensor
Open the hood and locate the air box. It should be on the
passenger side of the engine bay near the front of the vehicle. It will
be a plastic, box-shaped object with a large plastic pipe running to the
back of the engine.
Examine the new MAF sensor. You'll be looking for this
component in the air box.
Remove the air box cover and pull the air filter out.
Loosen the band clamps on the intake tubing with a
screwdriver and pull the intake tubing off of the air box.
Unplug the electrical connection to the MAF sensor and pull
the MAF sensor out of the air tube assembly.
Install the new mass airflow sensor and put the air box
assembly back together. Installation is the reverse of removal.
Hope this help to solve your problem (remember comment and rated this).
The mass flow sensor on the 1999 intrigue is along the intake tube right
after the air filter intake housing. Loosen the two clamps that hold the
MAF sensor between the Air filter box cover and air intake tube,
disconnect the wire leads at the MAF sensor connection and remove the
MAF. Note it's uncommon for the MAF sensor to go bad and 95% of the
time, cleaning it with MAF sensor with MAF cleaner will fix any problem
it may of had to trigger the DTC codes.
Start with trying to clean it first just by following the instruction on
the MAF cleaner. This should save you time and money to get your Intrigue
running 100% again soon.
Good luck and thank you for using Fixya.

should be a little single wire connected to the air filter box. located on the clean side of the air filter. if not it will be between the air filter box and the throttle plate usually located on the air duct hose going from the air filter box to the throttle plate.
