1A-102 Engine General Information and Diagnosis:
DTC P0223: Throttle / Pedal Position Sensor / Switch “B” (Sub) Circuit High
S7RS0B1104038
Wiring Diagram
Refer to “DTC P0222: Throttle / Pedal Position Sensor / Switch “B” (Sub) Circuit Low”.
DTC Detecting Condition and Trouble Area
4 ECM voltage check
1) Turn OFF ignition switch.
2) Remove ECM from its bracket with ECM connectors
connected.
3) Check for proper connection of ECM connector at “C37-
43” terminal.
4) If OK, measure voltage between “C37-43” terminal of
ECM connector and engine ground with ignition switch
turned ON.
Is voltage 4 – 6 V?
“RED” wire is open or
high resistance circuit.
Go to Step 5.
5 Wire harness check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between “C37-43” terminal of ECM
connector and engine ground.
Is resistance infinity?
Substitute a known-
good ECM and recheck.
“RED” wire is shorted to
ground circuit.
6 Wire harness check
1) Measure voltage between “WHT” 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-
40” and “C37-42” terminals.
3) If OK, measure resistance between “WHT” and “BLK”
wire terminals of electric throttle body connector.
Is resistance infinity?
Go to Step 8. “WHT” wire is shorted to
“BLK” wire.
8 Wire harness check
1) Measure resistance between “WHT” 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.
“WHT” 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 throttle position sensor (sub) is more than specified
value for specified time continuously.
