• An excessively high voltage from the sensor 

is sent to ECM for 0.2 seconds or more.

• An excessively difference between mini-

mum and maximum pressure signal from 
the sensor is sent to ECM while engine run-
ning.

• Harness or connectors

3.

CHECK MASS AIR FLOW SENSOR CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Check mass air flow sensor circuit for open and short.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK MASS AIR FLOW SENSOR 

Refer to 

ECK-194, "Component Inspection (Mass Air Flow Sensor)"

.

Is the inspection result normal?

YES

>> Replace error-detected parts.

NO

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

Component Inspection (Mass Air Flow Sensor)

INFOID:0000000010289767

1.

CHECK MASS AIR FLOW SENSOR

1.

2.

Reconnect all harness connectors disconnected.

3.

Turn ignition switch ON.

4.

Check the voltage between mass air flow sensor harness connector.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace mass air flow sensor.
