Where is the EGR valve on a 1995 Nissan Quest?
The EGR valve on the Villager/Quest is located at the top-rear drivers ride of the intake plenum. You will see 2 parts that look almost identical. They look almost like 2 little flying saucers. One is the BPT and the other is the EGR valve. A common problem on these vans, is the rubber tube that goes between the two parts. This hose usually cracks and splits or becomes plugged with carbon. This will trip the check engine light and an EGR code will be present. Replace the little rubber hose (its usually in stock at your Ford or Nissan dealer) and you should be good to go. Good Luck!
