97 Nissan Maxima

Check engine soon warning light on. Computer code reads: PO 325, PO 440, & PO 446A. Can not locate sensors. Help!

i dont recognize those codes

i dont recognize those codes

PO 325 Knock sensor, I know where this is. PO 440 purge central valve & PO 446A Canister purge cut valve, have no idea where to look or what they look like.

I changed the Valve on my max a month ago. It's behind the rear driver side wheel. It's a cheap part. Mine cost $32 at the dealership. I installed it in about 20 minutes. I'd suggest getting a chilton's manual for proper instructions.

So what is the name of the part that I would need to fix that problem? It sounds very easy to install, I've actually lifted my car and located a black box approx 9"/6". Is this the part???? :smile: if so when you detatched the fuel line, do you have to turn something off. Or can you just throw the part in there straight from the box? The part is for my sisters car she has a 96 max. I'm also having a problem with my car as well, the obd2 codes are 440 and 446. If you could reply it would help me out allot. :smokin: :2cents:
