Description
The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The greater air flow, the greater the heat loss.
Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The ECM detects the air flow by means of this current change.

Component Inspection
1.CHECK MASS AIR FLOW SENSOR-I
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
2.CHECK FOR THE CAUSE OF UNEVEN AIR FLOW VIA THE MASS AIR FLOW SENSOR
Check for the cause of uneven air flow via the mass air flow sensor. Refer to the following.
3.CHECK MASS AIR FLOW SENSOR-II
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Without CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
4.CHECK MASS AIR FLOW SENSOR-III
With CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Without CONSULT
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm
