ON±VEHICLE INSPECTION
1.INSPECTMASS AIR FLOW METER
(a)If you have hand±held tester: Inspect for operation
(1)Connect the hand±held tester to the DLC3.
(2)Turn the ignition switch ON.
(3)Blow air into the MAF meter, and check that the airflow fluctuates (MAF ) of the CURRENT DATA
shown the standard value.
If operation is not as specified, check the MAF meter (See page
10±56), wiring and ECM.
(b)If you have no hand±held tester: Inspect for operation
(1)Turn the ignition switch ON.
(2)Connect the positive tester probe of the voltmeterto the terminal VG of the ECM. and the negative tes-
ter probe of the voltmeter to the terminal EVG of the
ECM.
(3)Blow air into the MAF meter, and check that the volt- age fluctuates.
If operation is not as specified, check the MAF meter (See page
10±56), wiring and ECM.
2.INSPECT INTAKE SHUTTER
(a)Inspect the throttle control motor for operating sound. (1)Turn the ignition switch ON.
(2)When turning the accelerator pedal position sensor lever, check the running sound of the motor.
Also, check that there is no friction sound.
If operation is not as specified, check the throttle control motor (See page 10±56), wiring and ECM.
(b)Inspect the throttle position sensor. (1)Connect the hand±held tester to the DLC3.
(2)Turn the ignition switch ON.
(3)When turning the accelerator pedal position sensor lever to the full±\
open position, check thatthe throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA shown the
standard value.
Standard throttle valve opening percentage:
60 % or more
If operation is not as specified, check that the accelerator pedal positio\
n sensor (See page 10±56), wiring
and ECM.
If you have no hand±held tester, measure voltage between terminals (LU+A ± LU±A, LU+B ± LU±\
B) of the
ECM connector (See page 05±549).

(3)Blow air into the MAF meter, and check that the volt- age fluctuates.
If operation is not as specified, check the MAF meter (See page
10±20), wiring and ECM.
2. INSPECT POWER STEERING OIL PRESSURE SEN- SOR
(a) Using a voltmeter, measure the voltage between termi-
nals PSW and E2.
Voltage:
