DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
| 2 |
Inlet throttle valve (+) drive circuit and (–) drive circuit check
1)Check “A1” and “A2” circuits according to Step 2 of Inlet Throttle Valve Operation Check:D16AA.
Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.
|
| 3 |
Inlet throttle valve position sensor power supply circuit, signal circuit and ground circuit check
1)Check “B1”, “B2” and “B3” circuits according to Step 2 – 5 of Inlet Throttle Valve Position Sensor Check:D16AA.
Is check result OK?
|
Go to Step 4.
|
Repair or replace defective wire harness.
|
| 4 |
Inlet throttle valve position sensor check
1)Check inlet throttle valve position sensor.
Is check result OK?
|
