Canister Purge (CANP) Solenoid

WARNING: This page is about a different car, the 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect CANP solenoid harness connector. Set DVOM to 200-ohm scale. Measure resistance across CANP solenoid terminals. Resistance should be 30-90 ohms. If resistance is not as specified, replace CANP solenoid.
  2. Disconnect vacuum hose at CANP solenoid on manifold vacuum side. Apply 16 in. Hg vacuum to manifold vacuum side of solenoid. CANP solenoid should hold vacuum for 20 seconds.
  3. Faults in CANP solenoid or circuit should set a trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (3.0L) article. If no trouble code has been set, see CIRCUIT TEST KD in the TESTS W/CODES - EEC-IV (3.0L) article for additional solenoid and circuit testing.
