Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure

2.
CHECK THROTTLE POSITION SENSOR 2 POWER SUPPLY CIRCUIT
1.
Disconnect electric throttle control actuator harness connector.
2.
Turn ignition switch “ON”.
3.
Check voltage between electric throttle control actuator terminal
1 and ground with CONSULT-II or tester.
OK or NG
OK
>> GO TO 3.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
3.
CHECK THROTTLE POSITION SENSOR 2 GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch “OFF”.
2.
Disconnect ECM harness connector.
3.
Check harness continuity between ECM terminal 66 and electric throttle control actuator terminal 5.
Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 4.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK THROTTLE POSITION SENSOR 2 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Check harness continuity between ECM terminal 68 and electric throttle control actuator terminal 2.
Refer to Wiring Diagram.
2.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
