Canister Purge (CANP) Solenoid

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1995 Ford RV Cutaway, 1995 Ford Pickup, 1995 Ford F-Super Duty, 1995 Ford Econoline, and 1995 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Faults in CANP solenoid or circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (7.5L) article. If diagnostic trouble code has not been set, disconnect CANP solenoid harness connector.
  2. Measure resistance across CANP solenoid terminals. If resistance is not 30-90 ohms, replace CANP solenoid. If resistance is 30-90 ohms, disconnect vacuum hose at CANP solenoid on manifold vacuum side.
  3. Apply 16 in. Hg vacuum to manifold vacuum side of solenoid. CANP solenoid should hold vacuum for 20 seconds. If CANP solenoid does not hold vacuum for 20 seconds, replace CANP solenoid. If CANP solenoid holds vacuum for 20 seconds, solenoid is okay. If additional testing is required, see CIRCUIT TEST KD in TESTS W/CODES - EEC-IV (7.5L) article for circuit testing.
