INSPECTION
1. INSPECT MASS AIR FLOW METER
(a) Output voltage inspection.
(1) Apply battery voltage across terminals 1 (+B) and 2
(E2G).
(2) Using a voltmeter, connect the positive (+) tester
probe to terminal 3 (VG), and negative (±) tester
probe to terminal 2 (E2G).
(3) Blow air into the MAF meter, and check that the volt-
age fluctuates.
(b) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween terminals 4 (THA) and 5 (E2).

(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Resistance: 6.9 to 7.9
at 20
C (68
F)
(b) Movement inspection.
(1) Connect the positive (+) lead from the battery to ter-
minal 1 and negative (±) lead to terminal 2, and
check the movement of the valve.
NOTICE:
Confirm the valve does not adhere.
HINT:
Bad returning of the valve by entrance of foreign objects causes
subtle pressure leak to the advanced direction. Then, DTC can
be detected.
3. INSPECT THROTTLE BODY ASSY
(a) Check throttle body.
(1) Check that throttle valve shaft is not rickety.
(2) Check that each port is not stopped up.
(3) Check that throttle valve opens and closes smooth-
ly.
(4) Check that there is no clearance between the
throttle stop screw and throttle lever when the
closed throttle position.

nals PSW and E2.
Voltage:

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).
