DTC Troubleshooting
NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to
“Precautions For DTC Troubleshooting: ”.
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 Accelerator pedal position (APP) sensor assembly
mounting check
1) Check that accelerator pedal position (APP) sensor
assembly has been mounted to vehicle body properly
(no pinched floor carpet, etc).
Is it OK?
Go to Step 3. Reinstall accelerator
pedal position (APP)
sensor assembly
properly referring to
“Accelerator Pedal
Position (APP) Sensor
Assembly Removal and
Installation: in Section
1C”.
3 Accelerator pedal position 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 4.8 V or more?
Go to Step 4. Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”.
4 ECM voltage check
1) Disconnect connector from accelerator pedal position
(APP) sensor assembly with ignition switch turned OFF.
2) Check for proper connection to accelerator pedal
position (APP) sensor assembly at “ORN/BLU”, “BLU/
GRN” and “BLU/YEL” wire terminals.
3) If OK, measure voltage between “ORN/BLU” wire
terminal of accelerator pedal position (APP) sensor
assembly connector and vehicle body ground with
ignition switch turned ON.
Is voltage 4 – 6 V?
Go to Step 6. Go to Step 5.
“BLU/GRN”
“BLU/YEL”
