You check all the lines. Search here it was mentioned the canister in the back (I think, can't remember) the nipple breaks.
P0445 stuck in pending status
Anyone know if the PO442 (small leak) has to be passed successfully before the PO455 parameter will go active? I've put about 200 miles on the car since getting it back together from the timing cover leak but can't get the PO455 to come put of pending and as such I can't get the car inspection done to get it re-registered.
Reason I ask is the PO442 failed (it's done that for two years off and on, basically since it was tuned). Normally clear it and drive some more and all goes well bit not this time (combined with the 445 stuck at pending).

This might sound really simplistic, but are you sure its not the gas cap?
Driver's side front fascia, near fog light access hole...
Yes, I recently changed the gas cap. Been happening for a while off an on. My big concern is I can't get the PO455 to get off pending. I can pass inspection with just the PO442 fault but not with something pending. I've never had this problem getting the major leak check to actually happen and clear.
Pay an inspection place $100 and they can switch cars for the test and Walla inspection complete.

If it won't clear with a scan tool, you can always try disconnecting the battery and touching both cables together for 1min to lose the pending code, and see if it returns.
Codes clear fine. Just can't get PO455 to become active. Guess I'll just keep driving it and hoping the police don't take notice of my expired tag in the interim. Only 1 more year and I won't have to deal with this anymore as the car will be a classic.
Which state are you? Is the code pending, flagged (check engine light on), or is your EVAP checks not ready?
The reason why I mention is because some states will still pass you with a "pending" as long as EVAP checks are complete.
In Arizona we are allowed two "not ready" for pre-2000's.
Unfortunately other states are communist, no issues can be detected and all readiness compete.
I got so tired of waiting 3+ hrs in line for emissions tests I ended up registering the Viper & NSX as collectors (both are limited production "exotics"), which skips emissions - the only drawback is you must have collectors car insurance which usually has mileage and driving restrictions.

I'm in Texas and go through Williamson county emission testing. I'm pretty sure we can pass with just one pending. The PO442 does throw the CEL but I could clear that and still pass if I could get the PO445 to actually pass/get out of pending. Pretty sure these are both EVAP checks. I may have to check into collector car insurance again. Last time I did I noticed the mileage restrictions which aren't a big deal as I only drive this car about 2K miles a year anyway but it was the location restrictions that had me pass. The places I looked had stipulations that you could only take the car to shows and you were not allowed/covered when driving the car for pleasure like to work or even to run to errands in.Which state are you?

Hijack:& NSX
Ooooooh my wish list car.
Are you happy with it? Repairs?
My '96 manual doesn't have 0445 in the table. Closest ones are 0443 Evap purge solenoid (open/short condition), 0441 Evap purge flow monitor fail (low or high flow condition). I would suppose you have a bad connection on or a failing solenoid, or loose/damaged lines that are marginally operational.
Pretty happy with it. I bought it way back in 2012 for $24k. Just regular maintenance for the most part. I did have to rebuild the ABS modulator with fresh o-rings (most people just swap out with a modern module for an S2000). Timing belt is a bitch. I'm about due for another belt change, gotta refresh my valve cover gaskets and cam plugs while I'm in there.Hijack:

Like any other 90's limited production cars, parts are getting difficult to find. But I imagine 3d printing is going to solve a majority of those pitfalls.
It's far slower than what people expect, especially the early models with 5 speed gearbox (tall 2nd), but I have the Viper to go fast when I feel like it. Unlike most cars the NSX doesn't rust, so it can be driven in all weather conditions.
And - a final resolution posted in another thread:
I finally got my car registered (my constant EVAP low leak code wound up being the gas tank gasket) and the cars running good again.
Yeah, thanks for posting this as I had forgotten about this thread.And - a final resolution posted in another thread:
I found the leak by smoke testing the gas tank (stuck the pipe into the gas filler and sealed it off with a rubber glove). It was a super small leak that took forever to be visible but it finally did show up. If you run into the same, be sure to pull the carpet back and the cover off for the fuel pump sending unit. First time I tried this I didn't do this which is probably why I never saw the leak since it wasn't big enough to make it through those things.
As for getting the codes to get off pending. First time it took about 300 miles of combined city and highway usage. After finding and fixing the gas tank it took about 500 miles the second time to get off pending state. Not sure if their is a better driving pattern to run to get things to go faster but I would drive the car about 30 miles each drive. This would have a mixture of just putting around some back country roads all the way to 75mph highway driving. Getting these codes to finally get off pending was a major PITA.
I've been going through the Forums unchecking a bunch of "Following" threads. This is one I'm leaving checked.
