ON-VEHICLE INSPECTION
1. REMOVE V-BANK COVER
2. INSPECT SYSTEM OPERATION
(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 step 3), wiring and ECM.
(b) Inspect the accelerator pedal position sensor.
(1) Connect the TOYOTA hand-held tester or OBD II
scan tool to the DLC3.
(2) Check that the MIL does not come on.
(3) When turning the accelerator pedal position sensor
lever to the full- open position, check that the
throttle valve opening percentage (THROTTLE
POS) of CURRENT DATA shows the standard val-
ue.
Standard throttle valve opening percentage:
60 % or more
If operation is not as specified, check that the accelerator pedal
position sensor (See page DI-318), wiring and ECM.
If you have no TOYOTA hand-held tester or OBD II scan tool,
measure the voltage between terminal VPA and E2 of the ECM
connector.
(c) Inspect the air assist system.
(1) Start the engine and check that the MIL does not
come on.
(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 the condition with no electrical
load.
(d) After checking the above (b) to (d), perform the running
test and check that there is no incongruity.
3. INSPECT THROTTLE CONTROL MOTOR
(a) Disconnect the throttle connector.
(b) Using an ohmmeter, measure the motor resistance be-
tween terminal M+ and M-.
Motor resistance: 0.3 - 100 W at 20°C (68°F)
If the resistance is not as specified, replace the throttle body.
(c) Reconnect the throttle body connector.
4. INSPECT THROTTLE POSITION SENSOR (See page
DI-84)
If necessary, replace the throttle body.
NOTICE:
Be careful not to give a shock to the throttle body.
Be careful not to disassemble the throttle body.
5. REINSTALL V-BANK COVER

INSPECTION
1. REMOVE VSV
2. INSPECT VSV
(a) Inspect VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 30 - 36 W at 20°C (68°F)
If there is no continuity, replace the VSV.
(b) Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is a continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air flows from the ports E to F.
(2) Apply the battery positive voltage across the termi-
nals.
(3) Check that air flows from the ports E to F.
If operation is not as specified, replace VSV.
3. REINSTALL VSV

INSPECTION
1. INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
(a) Disconnect the vapor pressure sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminal 1 and 3 of the wiring harness side.
Voltage: 4.5 - 5.5 V
(d) Turn the ignition switch OFF.
(e) Reconnect the vapor pressure sensor connector.
2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Remove the fuel tank cap.
(c) Connect a voltmeter to terminal 2 and 3, and measure the
output voltage.
Voltage: 3.0 - 3.6 V
(d) Reinstall the fuel tank cap.
(e) Turn the ignition switch OFF.

NOTICE:
Never use SRS parts from another vehicle. When re-
placing parts, replace them with new parts.
Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.
