1. Disconnect the PCM connector.










2. Inspect the following wiring harness for open or short circuit (continuity check).

Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
- Variable swirl control solenoid valve terminal B and PCM terminal 4K
- Variable swirl control solenoid valve terminal A and main relay terminal C
