EVAP System Line (ES300)
- Warm up engine to normal operating temperature, then turn engine off. Install EVAP control system vacuum gauge to EVAP service port on purge line. See Fig 1. If using hand-held tester, connect hand-held tester to DLC3. Start engine. Push hand-held tester main switch on. Use ACTIVE TEST mode on hand-held tester to operate VSV for EVAP, then go to next step. If not using hand-held tester, disconnect VSV connector for EVAP. Connect battery leads to VSV terminals for EVAP. See Fig 2. Start engine, then go to next step.
- Check vacuum at idle. Vacuum should be .368-19.713 in. Hg for over 5 seconds. If vacuum does not change, hose connecting VSV to service port is loose or is blocked, or VSV is malfunctioning. If using hand-held tester, disconnect hand-held tester from DLC3, then go to next step. If not using hand-held tester, stop engine. Disconnect battery leads from VSV terminals. Reconnect VSV connector, then go to next step.
- Disconnect vacuum gauge from EVAP service port of purge line. Connect pressure gauge to EVAP service port on purge line. Using hose clipper, close off air drain hose at marked position. See Fig 3. Add 13.5-15.5 in. Aq. pressure from EVAP service port. Two minutes after pressure is added, gauge should indicate greater than 7.7-8.8 in. Aq. If pressure cannot be added, hose connecting VSV-canister-fuel tank has slipped off or VSV is open. Ensure pressure decreases when fuel tank cap is removed while adding pressure. See Fig 4. If pressure does not decrease when filler cap is removed, then hose connecting service port to fuel tank is blocked. Disconnect pressure gauge from EVAP service port on purge line.
