    NO 

    GO TO STEP 2  .

  2. CHECK FOR THE CAUSE OF UNEVEN AIR FLOW THROUGH MAF SENSOR

    1. Turn ignition switch OFF.
    2. Check for the cause of uneven air flow through MAF sensor. Refer to the following.

      • Improper specification of intake air system parts

    Is the inspection result normal?

    YES 

    GO TO STEP 4  .

    NO 

    GO TO STEP 3  .

  3. CHECK MAF SENSOR-II

    With CONSULT

    1. Repair or replace malfunctioning part.
    2. Start engine and warm it up to normal operating temperature.
    3. Connect CONSULT and select "DATA MONITOR" mode.
    4. Select "MASS AIR FLOW SENSOR (Hz)" and check the indication.
      Monitor item Condition Indication (Hz)

      Terminal
      F23 37 42 Ignition switch ON (Engine stopped.) Approx. 3, 700 Hz
      Idle (Engine is warmed-up to normal operating temperature.) 5, 100 - 5, 500 Hz
      2, 500 RPM (Engine is warmed-up to normal operating temperature.) 6, 100 - 6, 500 Hz
      Idle to about 4, 000 RPM 5, 100 - 5, 500 to Approx. 7, 000 Hz*

      * : Check for linear frequency rise in response to engine being increased to about 4, 000 RPM.

    Is the inspection result normal?

    YES 

    INSPECTION END

    NO 

    GO TO STEP 4  .

  4. CHECK MAF SENSOR-III

    With CONSULT

    1. Turn ignition switch OFF.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
