< COMPONENT DIAGNOSIS >

[QR25DE]

P0101 MAF SENSOR

1. Turn ignition switch OFF.

2. Reconnect all harness connectors disconnected.

3. Lift up the vehicle.

4. Turn ignition switch ON.

5. Connect CONSULT-III and select “DATA MONITOR” mode.

6. Select “MAS A/F SE-B1” and check indication.

7. Activate “INSPECTION MODE 1” (

HBC-104

) to start engine, and warm up engine to normal operating

temperature.

8. Depress the accelerator pedal and keep it.

9. Shift the selector lever to N position with engine running.

CAUTION:

Never leave the selector lever in the N position for a long period of time. In the N position, the

engine operates but electricity cannot be generated.

10. Select “MAS A/F SE-B1” in “DATA MONITOR” and check indication.

11. Shift the selector lever to P position.

12. Fully depress the accelerator pedal and keep it.

13. Check indication.

14. Fully release accelerator pedal then fully depress it.

15. Check for linear voltage rise in response to engine being increased to about 2,500 rpm.

Without CONSULT-III

1. Turn ignition switch OFF.

2. Reconnect all harness connectors disconnected.

3. Lift up the vehicle.

4. Turn ignition switch ON.

5. Check the voltage between ECM harness connector and

ground.

6. Activate “INSPECTION MODE 1” (

HBC-104

) to start engine,

and warm up engine to normal operating temperature.

7. Depress the accelerator pedal and keep it.

8. Shift the selector lever to N position with engine running.

CAUTION:

Never leave the selector lever in the N position for a long period of time. In the N position, the

engine operates but electricity cannot be generated.

>> GO TO 2.

2.

CHECK FOR THE CAUSE OF UNEVEN AIR FLOW THROUGH MASS AIR FLOW SENSOR

1. Turn ignition switch OFF.

2. Check for the cause of uneven air flow through mass air flow sensor. Refer to following.

-

Crushed air ducts

-

Malfunctioning seal of air cleaner element

-

Uneven dirt of air cleaner element

-

Improper specification of intake air system parts

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.
