'I have been through this on my 94 Altima, and let me warn you, it's not a walk in the park by any stretch of the imagination. The PCV valve is located beneath the intake manifold on the right (passenger) side. It threads into the breather seperator and points toward the center of the car. To remove it, you'll have to remove the Idle Air Control valve located on the end of the manifold log. Be aware that you'll have to do at least part of this task underneath the car, and that the IAC valve has antifreeze circulating through it (I found this out the HARD way!!!!!). It also might help to unbolt the breather seperator from the head. If you can afford it, pay a mechanic if it really needs to be done.
drop the pan, then the valve body, the solenoid is above that
how do you replace the ac evaportator
Gas tank
Located between the passengar and engine compartment.
The 1995 Nissan: temperature sensor is located on the front of the engine. The coolant temperature sensor will be near the thermostat housing.
AnswerThere isn't one. On the top of the head in the rear, there is a tube that runs to the breather. That is the straight ventilation. No PCV needed.
I don't believe that the altima had a crankshaft position sensor until 1995.
how do you reset the oil light on a 2000 altima

It is located near the firewall underneath the exhaust manifold. It's kinda hard to get to.
