Wiring Diagram
Refer to “DTC P2101: Throttle Actuator Control Motor Circuit Range / Performance”.
DTC Detecting Condition and Trouble Area
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.4Throttle actuator control relay circuit check
1) Remove throttle actuator control relay from individual
circuit fuse box No.1 with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control
relay at “BLK/RED”, “GRY”, “BRN” and “GRN” wire
terminals.
3) Measure voltage between engine ground and each
“BLK/RED”, “GRY” wire terminal with ignition switch
turned ON.
Is each voltage 10 – 14 V?Go to Step 5. “BLK/RED” wire and/or
“GRY” wire is open or
high resistance.
5Throttle actuator control relay circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance at following connector terminals.
• Between “BRN” wire terminal of throttle actuator
control relay connector and “E01-45” terminal of ECM
connector
• Between “GRN” wire terminal of throttle actuator
control relay connector and “E01-32” terminal of ECM
connector
Is each resistance below 5
Ω?Go to Step 6. “BRN” wire and/or
“GRN” wire is open or
high resistance.
6Throttle actuator control relay check
1) Check throttle actuator control relay referring to “Main
Relay, Fuel Pump Relay, Starting Motor Control Relay,
