NOTE: Perform the following inspection only when directed.
1. Disconnect MAP/boost air temperature sensor.
2. Measure the resistance between the MAP/boost air temperature sensor terminals A and B using a tester.
-
If not as specified, replace the MAP/boost air temperature sensor. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3 WITH
