DTC Detecting Condition and Trouble Area
Monitor signal of throttle actuator output (duty output) is inconsistent with
throttle actuator control command.
(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) Keep the accelerator pedal at idle position for 2 seconds.
4) Keep the accelerator pedal at fully depressed position for 2 seconds.
5) Repeat Step 3) and 4) for 3 times.
6) Check DTC.
DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting".
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Throttle actuator circuit check
1) Disconnect connectors from electric throttle body
assembly and ECM with ignition switch turned OFF.
2) Check for proper connection of electric throttle body
assembly and ECM connectors at "BLU" wire, "YEL"
wire, "C01-45" and "C01-44" terminals.
"BLU"
3) Turn ON ignition switch.
4) Measure voltage between "BLU" wire terminal of electric
throttle body assembly connector and engine ground,
between "YEL" wire terminal of electric throttle body
assembly connector and engine ground.
Is voltage 0 V?
3 Throttle actuator circuit check
1) Turn OFF ignition switch.
2) Measure resistance between "BLU" wire terminal of
electric throttle body assembly connector and engine
ground, between "YEL" wire terminal of electric throttle
body assembly connector and engine ground.
Is resistance infinity?
