Component Inspection

CHECK MASS AIR FLOW (MAF) SENSOR-1

With CONSULT

  1. Turn ignition switch OFF.

  2. Reconnect all harness connectors disconnected.

  3. Start the engine and warm it up to normal operating temperature.

  4. Select “MASS AIR FLOW SENSOR (g/s) B1” in “DATE MONITOR” mode of “ENGINE” using CONSULT and check the indication under the following condition.

    Monitor item Condition Indication
    MASS AIR FLOW SENSOR (g/s) B1 Ignition switch ON (Engine stopped.) 0 g/s
    Idle (Engine is warmed-up to normal operating temperature.) 2.09 - 3.51 g/s
    2,500 rpm (Engine is warmed-up to normal operating temperature.) 3.62 - 6.40 g/s
    Idle to about 4,000 rpm 7.49 - 14.04 g/s

Is the inspection result normal?

YES>>

GO TO 4.

NO>>

GO TO 2.

CHECK FOR THE CAUSE OF UNEVEN AIR FLOW THROUGH INTAKE AIR DUCT

  1. Turn ignition switch OFF.

  2. Check for the cause of uneven air flow through intake air duct. Refer to the following.
