6.3.3. Removal and installation of MAF, MAP, IAT sensors and sensor of temperature/pressure of air of pressurization

MAF sensor

 PERFORMANCE ORDER

  1. Separate the socket of the MAF sensor and weaken collars of its fastening.
  1. Remove the MAF sensor, if necessary replace it.
  2. Installation is made upside-down.

The arrow applied on the sensor case has to specify in the direction of an air stream.

MAP sensor

 PERFORMANCE ORDER

  1. Remove the top cover of the engine, separate the socket and remove the sensor.
Removal of the MAP sensor of V6 engines.
  1. At installation grease a sensor carving with vaseline. On V6 engines check a condition of sealing rings of the sensor and if necessary replace them.

IAT sensor

The IAT sensor is used only on 4-cylinder engines.


 PERFORMANCE ORDER

  1. Remove a rubber cover of the socket, separate it and remove the IAT sensor.
  1. Check a condition of a sealing washer and if necessary replace it.
  2. At installation grease a sensor carving with vaseline.

Pressurization air temperature/pressure sensor

On 4-cylinder engines the sensor of absolute pressure of air of pressurization, and on V6 engines – the combined pressurization air temperature/pressure sensor is used.


 PERFORMANCE ORDER

  1. Separate the socket and remove the sensor.
Removal of the sensor of temperature/pressure of air of pressurization.
  1. At installation grease a sensor carving with vaseline. On V6 engines check a condition of sealing rings of the sensor and if necessary replace them.
