DTC Detecting Condition and Trouble Area






Circuit Diagram










DTC Confirmation Procedure

1) Warm up engine to normal operating temperature.
2) Run engine at idle speed for 20 sec.

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 drive circuit check

Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect connectors.
Check for proper terminal connection to "C01", "E01" and throttle body assembly connectors.
If connections are OK, check the following points.
- Resistance of "B1" and "B2" circuits: less than 1 ohms
- Resistance of "B1" and "B2" circuits between throttle body assembly connector and ground: infinity
- Resistance between "B1" circuit terminal and other terminals at throttle body assembly connector: infinity
- Resistance between "B2" circuit terminal and other terminals at throttle body assembly connector: infinity
- Voltage of "B1" and "B2" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")

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

3. TP sensor (main) signal circuit check

Check the following points.
- Resistance of "C2" circuit: less than 1 ohms
- Resistance of "C2" circuit between throttle body assembly connector and ground: infinity
- Resistance between "C2" circuit terminal and other terminals at throttle body assembly connector: infinity
- Voltage of "C2" circuit: 0 - 1 V (with ignition mode of keyless push start system in "ON")

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

4. Throttle body assembly check

Check throttle body for operation and condition. Testing and Inspection

Is it in good condition?
YES -
Replace ECM and recheck DTC. Service and Repair
NO -
Replace throttle body assembly. Throttle Body Assembly Removal and Installation
