  1. Bring engine to normal operating temperature. Connect tachometer to engine. Increase engine speed from idle to 5000 RPM. Variable induction control valve shaft should turn.
  2. Disconnect variable induction control servo connector. Connect DVOM between both servo connector terminals to check servo coil resistance. Resistance should be 5-35 ohms. Replace servo if resistance is not 5-35 ohms.
  3. Apply 6 volts between both servo connector terminals. Ensure variable induction control servo shaft turns smoothly. Reverse voltage to servo connector terminals. Servo shaft should turn smoothly in opposite direction. If servo shaft does not function as described, replace air intake plenum assembly.
