Wiring Diagram
Refer to “DTC P2122: Throttle / Pedal Position Sensor / Switch “D” (Main) Circuit Low Input”.
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) 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
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and
confirm that the trouble has been corrected.
DTC detecting condition Trouble area
Output voltage of APP sensor (sub) is less than specified
value for 0.2 seconds continuously.
(1 driving detection logic)
• APP sensor (sub) circuit
• APP sensor
•ECM
• Incorrect mounting of APP sensor
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed?
Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 APP sensor mounting check
1) Check that APP sensor has been mounted to vehicle
body properly (no pinched floor carpet, etc.).
Is it OK?
Go to Step 3. Reinstall APP sensor
properly referring to
“APP Sensor Assembly
Removal and
Installation in Section
1C”.
3 APP sensor (sub) and its circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch, check “APP Sensor 2 Volt”
displayed on scan tool.
Is displayed voltage below 0.384 V?
Go to Step 4. Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
