The check engine light came on in our 2001 Toyota Highlander
We took it to AutoZone and had them check it and the gave us these results:
1.Defective or Loose Fuel Cap (not this one, checked it)
2.EVAP canister or hose cracked/not connected
3.Purge or vent solenoid defective
4.Vacuum leak at engine
How serious are these thing?
Can we check them ourselves?
Any quick-fix?
