WASTEGATE Solenoid

  1. Remove connector from multi-thermo switch and turn ignition on. Energize wastegate solenoid by momentarily brushing lead to wastegate solenoid at multi-thermo switch. Solenoid will click if operating properly.
  2. Remove connector from wastegate solenoid. Check voltage at connector terminal No. 1 (Green/Purple wire). Voltage should read approximately 12 volts. Turn ignition off and remove connector from electronic control unit.
  3. Using an ohmmeter, measure resistance between terminal No. 2 (Blue/Black wire) and terminal No. 19. Ohmmeter should read 0 ohms. If not, check for open circuit in wiring or connectors. If circuits are functional, replace wastegate solenoid.
