Wastegate Solenoid Valve

WARNING: This page is about a different car, the 1994 Plymouth Laser and 1994 Eagle Talon. However, it is still accessible from the selected car via links, so may be relevant.
  1. Wastegate solenoid valve is located on air cleaner assembly. Disconnect wastegate solenoid valve electrical connector and vacuum hose.
  2. Connect a hand-held vacuum pump to wastegate solenoid valve hose vacuum nipple. Apply vacuum. Vacuum should hold. If vacuum does not hold, replace wastegate solenoid valve. If vacuum holds, go to next step.
  3. With wastegate solenoid valve electrical connector disconnected, apply battery voltage to wastegate solenoid valve terminals. Apply vacuum with hand-held vacuum pump. Vacuum should not hold. If vacuum holds, replace wastegate solenoid valve. If wastegate solenoid valve does not hold vacuum, go to next step.
  4. Using an ohmmeter, check wastegate solenoid valve resistance. Connect ohmmeter leads between wastegate solenoid valve terminals. Ohmmeter should read 36-44 ohms at 68°F (20°C). If resistance is not within specification, replace wastegate solenoid valve.
