INJECTOR
ON-VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is normal operating noise
in proportion to engine speed.
(2) If you have no sound scope, you can check the in-
jector transmission operation with your finger.
If no sound is heard or unusual vibration is felt, check the wiring
connector, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the throttle body without disconnecting the
water bypass hoses from the air intake chamber.
(See page SF-42)
(b) Disconnect the 6 injector connectors.
(c) Using an ohmmeter, measure the resistance between the
injector terminals.
Resistance: Approx. 1.95 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(d) Reconnect the 6 injector connectors.
(e) Reinstall the throttle body to the air intake chamber.

THROTTLE BODY
ON-VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at the purge port.

Start the engine.

Check the vacuum with your finger.
Port nameAt idleAt 3,000 rpm
PurgeNo vacuumVacuum
2. INSPECT DASHPOT
(a) Warm up engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed.
Idle speed (Transmission in neutral position):
650 ± 50 rpm
(c) Check and adjust dashpot setting speed.
(1) Disconnect the control cables from the throttle
body.
(2) Turn the throttle linkage until the dashpot adjusting
screw starts to separate from the push rod. Then
keep the throttle linkage at that position.
(3) Check that the dashpot is set.
Dashpot setting speed: 2,300 ± 400 rpm
(4) Reconnect the control cables to the throttle body.
(d) Check VTV operation
(1) Maintain the engine speed at 3,500 rpm.
(2) Release the throttle valve, and check that the en-
gine returns to idle in a few seconds.

3. INSPECT THROTTLE OPENER
(a) Warm up engine
Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed
Idle speed (Transmission in neutral position):
650 ± 50 rpm
(c) Check throttle opener setting speed
(1) Disconnect the throttle opener vacuum hose from
the throttle body, and plug the throttle body port.
(2) Maintain the engine speed at 2,500 rpm.
(3) Release the throttle valve.
(4) Check that the throttle opener is set.
Throttle opener setting speed: 1,500 ± 200 rpm
(5) Adjust the throttle opener setting speed by turning
the throttle opener adjusting screw.
(6) Reconnect the throttle opener vacuum hose to the
throttle body.

(e) Inspect the PPS solenoid valve circuit.
(1) Disconnect the PPS ECU connector.
(2) Check continuity between the terminals of the con-
nector on wire harness side, as shown in the illustra-
tion.
Tester connectionSpecified condition
1 - 6No continuity
2 - 6No continuity
If it is not as specified, repair or replace wire harness or connec-
tor.
(3) Connect the PPS ECU connector.
4. INSPECT PPS ECU
(a) Jack up the vehicle and support it on stands.
(b) Start the engine.
(c) Measure the voltage of ECU.
(1) Using a voltmeter, measure the voltage between
ECU terminals 2 and 6 while the engine is idling.
Standard voltage: 0.15 - 0.20 V
(2) Place the transmission in gear and while running at
about 62 mph (100 km/h), measure the voltage be-
tween ECU terminals 2 and 6.
Standard voltage:
2JZ-GE: 0.06 - 0.17 v
2JZ-GTE: 0.07 - 0.17 v
If no voltage, try another ECU for SUPRA.
(d) Lower the vehicle.
