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 ºDIAGNOSIS / OBD/
MOBD / DATA LIST / ALLº shown the standard val-
ue.
If operation is not as specified, check the MAF meter (See page
10±20), 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±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:
ConditionVoltage (V)
Not spin the steering wheel at engine idling9 to 14
Spin the steering wheel at engine idling0 to 3

(a)Using a voltmeter, measure the voltage between termi-
nals PSW and E2.
Voltage:
ConditionVoltage (V)
Not spin the steering wheel at engine idling9 to 14
Spin the steering wheel at engine idling0 to 3
3.INSPECT THROTTLE BODY
(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±39), 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±39), wiring
and ECM.
If you have no hand±held tester, measure voltage between terminals (VTA1 ± E2, VTA2 ± E2) of the ECM
connector (See page 05±318).
(c) Inspect the air assist system.
(1) Start the engine and check that the CHK ENG does not light up.
(2) Allow the engine to warm up to normal operating temperature.
(3) Turn the A/C compressor ON to OFF, and check the idle speed.
Idle speed (Transmission in neutral): 700
50 rpm
NOTICE:
Perform inspection under condition without electrical load.
(d) After checking the above (b) to (d), perform the driving test and check that there is no sense of incon-
gruity.
4. INSPECT ACCELERATOR PEDAL POSITION SENSOR
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Check that the voltage (ACCEL POS) of the CURRENT DATA shown the standard value.
Accelerator pedal released: 0.5 to 1.1 V
Accelerator pedal depress: 2.6 to 4.5 V
(d) Check that the voltage (ACCEL POS #2) of the CURRENT DATA shown the standard value. Accelerator pedal released: 1.2 to 2.0 V
Accelerator pedal depress: 3.4 to 5.3 V
If you have no hand±held tester, measure voltage between terminals (VPA ± EPA, VPA2 ± EPA2) of the ECM
connector (See page 05±318).
