10-6.17. Manifold Air Temperature (MAT) Sensor Removal
Two Manifold Air Temperature (MAT) Sensors are mounted in the balanced manifold,
intake manifold, or throttle body depending upon the engine model as shown in Figure
10-46. These thermistor-type sensors are installed using compression fittings that are
threaded into tapped bosses on the throttle body and the intake manifold. The sensors are
an integral part of the engine low voltage harness.
Procedure
1.
Disconnect engine electrical power.
2.
Cut and remove cable ties as necessary for clearance to remove the sensor.
3.
Loosen and fully unthread the temperature sensor compression fitting nut and slide
the sensor out of the compression fitting.
4.
Prepare the new sensor leads according to Section 10-5.2, “Non-EGT Sensor and
Lead Wire Replacement.”
