KT3 - Check IMRC Circuit Continuity

- Key "OFF".

- Intake Manifold Runner Control System (IMRC) solenoid disconnected.

- Disconnect Powertrain Control Module (PCM). Inspect for damaged pins, corrosion, loose wires etc. Service as necessary.

- Install breakout box, leave PCM disconnected.

- Measure resistance between test pin 32 at the breakout box and IMRC circuit at the IMRC solenoid vehicle harness connector.

- Is resistance less than 5.0 ohms?

Yes -- Go to KT4. KT4 - Check IMRC Circuit For Short to Ground

No -- Service open circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
