(6) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state,
check to see that there is no leak on any part of the
fuel system.
NOTICE:
Always pinch the hose. Do not bend as it may cause the
hose to crack.
(7) Turn the ignition switch OFF.
(8) Disconnect the TOYOTA hand-held tester from the
DLC3.

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.

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.
