Variable Induction Control Motor

WARNING: This page is about a different car, the 1994 Mitsubishi Diamante. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect VIC motor harness connector. Using DVOM, measure resistance between motor connector terminals. Resistance should be 5-35 ohms. Replace VIC motor if resistance is not as specified.
  2. Apply 6 volts between both servo connector terminals. Ensure variable induction control motor shaft turns smoothly. Reverse voltage to motor connector terminals. Motor shaft should turn smoothly in opposite direction. If shaft does not function properly, replace air intake plenum assembly.
  3. Check for continuity in circuit between control motor harness connector and ECM. Disconnect VIC motor connector and ECM connector. Connect DVOM to Green/Black wire of VIC connector and vehicle ground. Ground terminal No. 109 (Fed. models) or terminal No. 39 (Calif. models) of ECM. If continuity exists, go to next step. If continuity does not exist, repair as needed.
  4. Connect DVOM to Green/White wire of VIC connector and vehicle ground. Ground terminal No. 110 (Fed. models) or terminal No. 40 (Calif. models) of ECM. If continuity does not exist, repair as needed. If continuity exists and all preceding tests do not show any system or component malfunction and ECM is suspected, substitute ECM with known good component and retest.
