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. Knock sensor signal circuit and ground circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C01", "E01" and knock sensor connectors.
Check for proper terminal connection to "C01", "E01" and knock sensor connectors.
If connections are OK, check the following points.
- Resistance of "A1" and "A2" circuits: less than 1 ohms
- Resistance of "A1" circuit between knock sensor connector and ground: infinity
- Resistance between "A1" circuit terminal and other terminal at knock sensor connector: infinity
- Voltage of "A1" and "A2" 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. Knock sensor check
Check knock sensor. Knock Sensor Inspection
Is it in good condition?
