Cool

1mz-fe v6, or 5s-fe i4?

Either way there are two larger black hoses on the passanger side of the upper intake air chamber (highest part of the engine).

One goes to a metal pipe on the firewall that goes to your brake booster (big circular thing your brake cylinder sits on{the thing that holds the brake fluid})
The other one that goes maybe 8-10 inchest to the valve cover of the motor is the PCV hose.


The PCV valve is normally a little white plastic thing that either snaps out when you pull realy hard, or brakes. It's like a $5 part.
If it's an I4 the o2 sensor is on the exhaust manifold staring you in the face.
If it's a v6 you have one on each exaust manifold (front like the i4, and one in the back, on the rear manifold) and if you have a California emessions car, one after the catalitic convertor.





May I ask, why do you want to know where the PCV valve, and o2 sensor<s> are?

do a search on o2 sensors. i recently asked the same question. i got some mixed answers at first but i think it was clearified by the end of the post. a haynes manual would also tell you exactly which sensor is which. b1 s1, or b2 s1 etc. there is a great picture in the haynes. search "o2 sensor" in this forum youll get the answers you need.

OK, you have 3 o2 sensors evidently, and the puzzle goes like this bank 1 is the bank with #1 cylinder in it usually and sensor 1 is in the manifold and sensor 2 is in the pipe, so b1s1 is in the manifold of the side of the motor with #1 cylinder in it and b2s1 is the sensor in the other manifold, now each bank may have its own downstream o2 or the car may have just 1 downstream just past the last cat in the y pipe, this is b1s2 or b2s2

^^has them for $99.15. cheapest ur gonna get unless you buy a universal one and splice the connector on yourself. i hear the bosch ones come with a pretty nifty splicing kit. ive never used it myself but its an option.(much cheaper!!!)

make sure you figure out which sensor you need so you dont spend more than you have to.

also, i checked my haynes and there is a perfect diagram on page 6-5 that shows which sensor is which.
