On four cylinder vehicles MAP/IAT sensor is mounted on the intake manifold at the end of the air inlet tube. Start by unscrewing the cable that connects to the negative terminal of the battery, then remove the electrical connector of the MAP/Intake Manifold Temperature Sensor. Subsequently, extract the mounting bolt and slide out the sensor from the intake manifold; the process of installation is done in a reverse manner. For 2011 And Later V6 Models, You'll Be Using A Barometric Pressure/Intake Manifold Temperature (BPS/IAT) Sensor That Is Mounted On Top Of The Air Filter Housing: First, Loosen The Cable Connecting The Negative Terminal Of The Battery. After that unbend the electrical connector to the BPS/IAT sensor, unbolt its mounting bolts and then pull out the sensor above the air filter housing and its installation process will be the reverse of the extraction process.
