EVAP Canister Purge System Inspection
- Warm up engine to normal operating temperature.
- Hoist vehicle so that all wheels rotate freely.
- Set M/T in "Neutral" or A/T in "P" position and parking brake.
- Disconnect purge hose (1) from purge pipe.
- Place finger against the end of disconnected hose (1) and check that vacuum is not felt there when engine is running at idle speed.
- Release parking brake lever, set transfer in "2WD" and M/T in "1st" or A/T in "L".WARNING: Make sure that transfer is set to "2WD" range position for this check. If it is set to "4WD" or "4L" position, front and rear wheels turn at high speed and a very dangerous situation may occur.
- Also check that vacuum is felt when engine speed is increased to higher than about 1,500 r/min. and keep it for 3 min. or more. If check result is not described in Steps 5 and 7), check EVAP canister purge valve, wire harness and vacuum passage.
