On-Vehicle Inspection [09/2015 - ]: Procedure

  1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY 
    1. Read the value using the Techstream (MAF).
      NOTE:
      • Perform the inspection with the vehicle indoors and on a level surface.
      • Perform the inspection of the mass air flow meter while it is installed to the air cleaner case (installed to the vehicle).
      • During the test, do not use the exhaust air duct to perform suction on the exhaust pipe.
      1. Turn the engine switch on (IG) (do not run the engine).
      2. Turn the tester on.
      3. Enter the following menus: Powertrain / Engine / Data List / All Data / MAF Sensor 1 or MAF Sensor 2.
      4. Wait 30 seconds, and read the values on the Techstream.
