DTC Detecting Condition and Trouble Area
NOTE
When DTC P0123 and P0223 are indicated together, it is possible that “RED” wire shorted to power
circuit and/or “BLK” wire open.

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. 6
Wire harness check
1) Measure voltage between “GRN” wire terminal of electric
throttle body connector and engine ground with ignition
switch turned ON.
Is voltage 4 – 6 V? Go to Step 9. Go to Step 7.
7 Wire harness check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Check for proper connection of ECM connector at “C37- 54” and “C37-42” terminals.
3) If OK, measure resistance between “GRN” and “BLK” wire terminals of electric throttle body connector.
Is resistance infinity? Go to Step 8. “GRN” wire is shorted to
“BLK” wire.
8 Wire harness check
1) Measure resistance between “GRN” wire terminal of
electric throttle body connector and engine ground with
ignition switch turned OFF.
Is resistance infinity? Substitute a known-
good ECM and recheck.
“GRN” wire is shorted to
ground circuit.
9 Electric throttle body check
1) Check TP sensor referring to “Throttle Position Sensor
Performance Check” under “Electric Throttle Body
Assembly On-Vehicle Inspection in Section 1C”.
Is output voltage within specified value? Substitute a known-
good ECM and recheck.
Replace electric throttle
body.
Step Action Yes No
DTC detecting condition
Trouble area
Output voltage of TP sensor (main) is more than specified
value for specified time continuously.
