EVAP Bypass Solenoid Valve Test

  1. Disconnect vacuum hose from EVAP 2-way valve as illustrated. See Figure . Turn ignition on. Using vacuum pump, slowly apply vacuum to EVAP 2-way valve as illustrated. See Figure . If vacuum does not hold, go to next step. If vacuum holds, EVAP bypass solenoid valve and EVAP 2-way valve are okay at this time. Perform EVAP control canister vent shut valve test. See EVAP CONTROL CANISTER VENT SHUT VALVE TEST  .
  2. Turn ignition off. Disconnect EVAP bypass solenoid valve connector. Check for continuity between ground and EVAP bypass solenoid valve harness connector terminal No. 2 (Blue wire). If continuity exists, go to next step. If continuity does not exist, replace EVAP bypass solenoid valve and "O" rings.
  3. Disconnect PCM 32-pin connector "A". Check for continuity between ground and EVAP bypass solenoid valve harness connector terminal No. 2 ( Blue wire). If continuity exists, repair short in Blue wire between EVAP bypass solenoid valve and PCM 32-pin connector "A" terminal No. 3. If continuity does not exist, substitute a known-good PCM and recheck. See SUBSTITUTING PCM in SELF-DIAGNOSTICS - INTRODUCTION article. If symptom or problem goes away, replace original PCM.
