Canister Purge (CANP) Solenoid

  1. Faults in CANP solenoid or circuit should set a service code. See QUICK TEST in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. If service code has not been set, disconnect CANP solenoid harness connector.
  2. Measure resistance across CANP solenoid terminals. Resistance should be 40-90 ohms. If resistance is not as specified, replace CANP solenoid. If resistance is as specified, 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, see CIRCUIT TEST KD in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section for circuit testing.
