Wiring Diagram
Refer to "DTC P2101: Throttle Actuator Control Motor Circuit Range / Performance: For Petrol Engine Model".
DTC Detecting Condition and Trouble Area
DTC detecting condition
Power supply voltage of throttle actuator control circuit is
more than 5 V for specified time even if throttle actuator
control relay is turned off.
(1 driving detection logic)
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Ignition switch turned OFF for 20 sec. or more.
4) Turn ON ignition switch and check DTC.
DTC Troubleshooting
NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting: For Petrol Engine Model".
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Throttle actuator control relay circuit check
1) Remove throttle actuator control relay from relay box
with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control
relay at "BLU/BLK", "BLU/RED", "BLU/ORN" and "GRN"
wire terminals.
3) Turn ON ignition switch.
4) Measure voltage between engine ground and "E23-17"
terminal of ECM connector.
Is voltage 0 V?
3 Throttle actuator control relay circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between engine ground and "E23-
50" terminal of ECM connector.
Is resistance infinity?
4 Throttle actuator control relay check
1) Check throttle actuator control relay referring to "Control
Relay Inspection: For Petrol Engine Model in Section
1C".
Is it in good condition?
