(3)

Measure the voltage between terminal No. 2 and ground.

Voltage should be battery positive voltage.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is  battery  positive  voltage  (approximately  12  volts)

present?

YES:

 Go to Step 4.

NO:

 Repair harness wire between the MFI relay connector

A-33X (terminal No. 2) and the mass airflow sensor A-07
(terminal No. 2) because of open circuit or short circuit
to ground. Then go to step 6.

STEP 4. Check for open circuit or short circuit to ground
between the mass airflow sensor connector A-07 and ECM
connector B-11.

(1)

Disconnect  the  mass  airflow  sensor  A-07  and  the  ECM
connector B-10.

Measure  the  resistance  between  the  mass  airflow  sensor
connector  A-07  (terminal  No.  3)  and  ECM  connector  B-11
(terminal No. 87).

Should be less than 2 ohms.

Check  for  the  continuity  between  the  mass  airflow  sensor
A-07 (terminal No. 3) and ground.

Not continuity.

Q:Is the harness wire in good condition?

YES:

 Go to Step 5.

NO:

 Repair it. Then go to Step 6.

STEP 5. Replace the mass airflow sensor.

(1)

Replace the mass airflow sensor.

(2)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  24  P.
13Ab-8.

DIAGNOSTIC TROUBLE CODE PROCEDURES

(3)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0102 set?

YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 6.

NO:

 The inspection is complete.

STEP 6. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  24  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0102 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

CIRCUIT OPERATION

The mass airflow sensor power is supplied from the
MFI  relay  (terminal  No.  4),  and  the  ground  is
provided on the ECM (terminal No. 88).

A voltage that is according to the mass airflow rate
is sent to the ECM (terminal No. 87) from the mass
airflow sensor output terminal (terminal No. 3).

TECHNICAL DESCRIPTION

While the engine is running, the mass airflow sensor
outputs  voltage  which  corresponds  to  the  mass
airflow rate.

The ECM checks whether the voltage output by the
mass airflow sensor while the engine is running is
within a specified range.

DESCRIPTIONS OF MONITOR METHODS

Compare  load  value  with  mass  airflow  sensor
output voltage.

MONITOR EXECUTION
