MASS AIR FLOW METER(w/ Glow Plug Controller) INSPECTION

PROCEDURE

  1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY

    1. A334357C01

      *a

      Thermistor

      Perform a visual check for any foreign matter on the temperature sensor (thermistor) of the mass air flow meter sub-assembly shown in the illustration.

      OK

      There is no foreign matter.

      If the result is not as specified, replace the mass air flow meter sub-assembly.
