Variable Induction System: Testing and Inspection

1. Open the fuse box cover.
2. Connect the SSTs (NGS tester) to the DLC-2.
3. Access ECT PID.
4. Verify ECT PID is 60 °C {140 °F} or less.
5. Start the engine.




6. Verify that the rod of VTCS shuter valve actuator is pulled.
- If the rod is not pulled, inspect the following.
- VTCS shutter valve actuator
- VTCS check valve (one-way)
- Vacuum hose
- VTCS solenoid valve
- Wiring harness and connectors (Main relay - VTCS solenoid valve - PCM terminal 2N)

7. Access RPM and IMRC PIDs.




8. Inspect the rod operation and IMRC PID under the following condition.
- If the rod operation and IMRC PID are not as specified, inspect the following:
- VTCS shutter valve actuator
- Delay valve
- Vacuum chamber
- Vacuum hose
- VTCS solenoid valve
- Wiring harness and connectors (Main relay - VTCS solenoid valve - PCM terminal 2N)
