I have a 98 I30 with 83k that is giving me a SEL for DTC P1446. Anybody had this code and what's it for and how much is the part to fix this thing.

4th gen ECU stickies.

I looked at the 4th gen stickies and have found nothing for P1446. Am I missing something.

the code u have is odbII, the ones in the stickies have the manual method of obtaining the codes.
Follow the instructions on how to get those numbers with a screw driver.

P1446 - EVAP Canister Vent Control Valve (Close)

EVAP! Have fun with that one...

Ok. Where is this valve and is it EXPENSIVE? OBD2 monitors too many things.

Behind the driver's side rear wheel. There is a black canister tht is a bit smaller than a shoebox. There is a valve/gadget thingy attached to it. That is usually the cluprit. I could not get mine OUT, though, so I just lived with the CEL on. I was about to fix it when the car got totalled. I wrote a thread on how to fix it a while back.

Well now that is an unusual place to find something. I will check it out. THANKS.

What do you mean?

I mean is that the charcoal canister for a most GM vehicles is under the hood. I am not used to looking in the tail end of the car for it. I did look and found the canister with no trouble. I took the purge valve off and cleaned it and put it back together and now I get a code P0446 in addition to my P1446 so I checked www.car-part.com and found a 98 I30 and they want $50 for that whole canister assembly. If these purge valves are prone to failure, please let me know as I called the Infiniti dealer and the purge valve is $72. I don't want this nickel and diming me to death. I hate to buy the $72 part and find that there is more causing this P1446 and now P0446 code. Again I don't want to buy a 7 year old junkyard part and have the same issues if this is a common problem for the I30's.

Ah, gotcha. Well, most people have found that cleaning the purge control valve with carb cleaner or a similar product will fix the problem. Did you reset the codes in the ECM after you cleaned the valve?

Yes I did and I cleared the P1446 but the P0446 is stuck. I haven't checked to see if the car has set the P1446 again or not.

Ok. 4 days and no P1446. But I still have the new P0446 which is EVAP Emission Control System Vent circuit Malfunction. I can clear the code and recheck and I have the P0446 back as a pending code and as soon as I start the car the SEL light is on. What did I bugar up when I took the purge valve off?

PLEASE GIVE ME SOME GUIDANCE.

Did you 2x check to be sure that you re-connected all of the wiring?

There was only 1 plug that I unhooked. I didn't remove the whole canister assembly. Just the purge valve.
