DTC Detecting Condition and Trouble Area






Wiring Diagram

Refer to P0122 DTC P0122 / P0123.

DTC Confirmation Procedure

1) Warm up engine to normal operating temperature.
2) Run engine at idle speed for 20 sec.
3) Run engine at 3,000 rpm for 20 sec.
4) Repeat Step 2) through 3) for 3 times.

DTC Troubleshooting

1.
Was "Engine and Emission Control System Check" performed?
YES -
Go to Step 2.
NO -
Go to Engine and Emission Control System Check Engine and Emission Control System Check.

2. Throttle actuator power supply circuit check

Turn OFF ignition switch and disconnect connectors from ECM.
Check for proper terminal connection to ECM connectors.
If connections are OK, turn ignition switch to ON position.
Check that throttle actuator power supply circuit (A4) is battery voltage.

Is it in good condition?
YES -
Go to Step 3.
NO -
Repair or replace defective wire harness.

3. Throttle actuator drive circuit check

Turn OFF ignition switch and disconnect connector from throttle body assembly.
Check for proper terminal connection to throttle body assembly connector.
If connection is OK, check that throttle actuator drive circuit (open and close) (B1 - B2) is as follows.
- Wiring harness resistance of each throttle actuator drive circuit is less than 3 ohms.
- Insulation resistance of each throttle actuator drive circuit is infinity between throttle body assembly connector and vehicle body ground.
- Insulation resistance of wire harness is infinity between each throttle actuator drive circuit terminal and other terminals at throttle body assembly connector.
- Circuit voltage of each throttle actuator drive circuit is 0 - 1 V with ignition switch in ON position.

Is it in good condition?
YES -
Go to Step 4.
NO -
Repair or replace defective wire harness.

4. TP sensor (main) signal circuit check

Check that TP sensor (main) signal circuit (C2) is as follows.
- Wiring harness resistance of TP sensor (main) signal circuit is less than 3 ohms.
- Insulation resistance of TP sensor (main) signal circuit is infinity between throttle body assembly connector and vehicle body ground.
- Insulation resistance of wire harness is infinity between TP sensor (main) signal circuit and each terminal at throttle body assembly connector.
- Circuit voltage of TP sensor (main) signal circuit is 0 - 1 V with ignition switch in ON position.

Is it in good condition?
YES -
Go to Step 5.
NO -
Repair or replace defective wire harness.

5. Throttle body assembly check

Check throttle body for operation and condition. Testing and Inspection

Is it in good condition?
YES -
Substitute a known-good ECM and recheck.
NO -
Replace throttle body assembly.
