I am looking for diagram of the engine to replace a pcv valve. 2002 Nissan Sentra 1.8
If it is like my 2001 Nissan Sentra, there is a cover behind the drivers side tire. It bolts on in the front and 2 quills click into the charcoal cannister. The cover comes off and the white plastic piece is the vacuum cut valve bypass valve. Nissan price $140.00-Wilton Nissan. I also did as recommended, and replaced the valve on the cannister, and the solenoid -the bolt on the canister broke as is evidently common. Replace cannister. Whole job (I did the labor) about $600.00
The purge control valve is located behind the rear wheel that is on the same side as the gas tank. By simplysliding under the bumper one can view the canister and the valve.
underneath the rear of the vehicle near the spare tire if i remember right. it is on the side of a black box (evap canister) it is the "vent control valve". it could be other things than just the valve itself setting this code.
On the back underneath the trunk. The black box between the Mufler & bumper area.
