(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.
