I made this video/slideshow to demonstrate an alternative to replacing the passenger side check valve on my 2003 C5. I got the P1416 code a couple of months ago when the weather was starting to get cold. At first the code could be cleared and not come back for a couple of weeks but after a month it would come back daily. I tried the Bill Curlee cleaning method, with carb cleaner, which worked for a week but then I got this alternative idea on how to fix it. The reason for this fix is because I didn't want to remove the fuel rails and intake manifold because I live in an apartment and working on the car is not allowed. Not to mention this is my daily driver and if something were to go wrong while removing the fuel rails and intake then I would have no way to get to work. Lastly this seemed to be a more complex and risky job than what I was up for.
The benefit for doing it this way is that if you ever have to replace the passenger side check valve in the future its an easy job. Also this is an inexpensive DIY fix, costs approximately $40-$65.
For those who are willing and comfortable taking the fuel rails and intake manifold off to replace the passenger side check valve this fix is not for you.
I'm proud how well it turned out.




Below is the 20minute live companion video to the above.

This is pretty slick. Need a new inspection sticker soon, but keep popping the P1416 code. This may be my solution.

 

I really whis I had seen this 4 months ago;Before I had to be at the Mercy of the dealer to have this done.You can bet next time I will use this.My 2001 Chevy pickup has these on both sides and easy to get to,On the Corvette this stock set-up is a JOKE!!!> Thanks for the Great video

 

Excellent! - I've been really lucky w/my 2003 Z (97k miles). When the weather turned cool, last October, I sprung a P1416 code. Read all the posts here about it, cleared the code, and it has yet to return. We've had an abnormally warm winter in MA and the roads have been good enough to allow me to use the Z all winter (only one week of shutdown due to snow). However, when the code does reappear, I've downloaded your slideshow and will surely use your repair tactics.

As a bit off-topic - I've had great luck with this car since I bought it a year ago. It was a salvage titled vehicle that I repaired and had the infamous "steering column" message every time I started it. It wasn't a major issue because the lock must have been removed before I bought it - the steering wheel turns with the key out of the ignition. It was just a matter of hitting the "reset" button after I started the car, and the column message would disappear. However, the other day I forgot to turn off the parking lights and the battery was completely drained when I went to start it the next day. After recharging the battery, lo and behold, no more "column lock" message! This is the best Chevy I've ever owned! And another thank you to 03newjersey!

 

nice fix, I may give this a try rather than fiddle with cleaning the stupid thing. Seems easy enough.

 

gotta love FL with no emissions inspections, just ripped the whole thing out.

 

Seriously? It takes 20-30 minutes to pull the intake off a C5, another 10 minutes of struggle to get the passengers side check valve out, replaced, and back in. You could do the whole thing in an Autozone parking lot in under an hour and not end up with a cobbled mess.

To be fair, I have had my intake off a few times, It goes quick after the first go-around.

 

Arnie,
You are missing the point of the fix. This fix is for those of us who do not want to remove the intake. Unlike you, we have not removed the intake several times before. And for someone who did not remove the intake before it would take at least 2 hours to carefully do it the right way without breaking anything. Also the end result for this fix is a more simplistic design, with less connection points and easy access to the passenger side check valve. The, "cobbled mess" you speak of is the original design which buries the check valve behind the intake manifold and is bolted down to insure complete inaccessiblity for troubleshooting and replacement. This Alternative Fix only takes 30-40 minutes for a first timer and after doing it once I don't have to do it again! If I get a P1416 code I can pop off the passenger side check valve in 3 minutes! By your own admission it takes you 40 minutes to replace the passenger side check valve. The first time I'm sure took you longer lets say 80 minutes. Thus if one had to troubleshoot or replace the passenger side check valve it would take...

1st Time (Troubleshoot or Replace)
Arnie's Way=80 minutes
Alternative Fix=40 minutes

2nd Time (Troubleshoot or Replace)
Arnie's Way=2 hours
Alternative Fix=43 minutes

3rd Time (Troubleshoot or Replace)
Arnie's Way=2 hours and 40 minutes
Alternative Fix=46 minutes

If you are the kind of guy who likes to pull the intake off every time you get a simple P1416 code than more power to you. I'll spend that same amount of time driving my vette and enjoying it.

 

First of all newjersey, quit patting yourself on the back for your self-perceived miracle fix! The location of the Bank 2 A.I.R check valve, behind the intake manifold, was carefully selected by GM engineers for reasons other than making it difficult to replace.

Their main consideration was to achieve a balanced air flow, to both check valves, without having to increase the size of the air supply hose feeding the passenger side valve.

You mentioned that the original design is "bolted down to insure complete inaccessibility". Actually, the Bank 2 air tube bracket has an open slot, and it only requires loosening a single bolt, with a 13mm wrench, to remove the air tube and check valve assy.. You don't even have to fully remove the bolt. It explains it all here: http://forums.corvetteforum.com/c5-t...eck-valve.html

If your the kind of guy who likes to cobble up a fix, instead of doing it right, then more power to you as well! I prefer to open my hood and see things the way they should be, and have the satisfaction of knowing that I did it right.

 

Quicksilver,
Prior to my little write up and post I read all the other posts on this forum regarding the P1416 code including the one you listed. In that post members talk about the difficulty in removing and replacing the passenger side check valve thus they hope that they can clean it by spraying carb cleaner upstream for a temporary fix (which concludes that cleaning is not a permanent fix). I see after you tried to clean it, with no luck, you and your son spent 4 hours and removed the intake and replaced the check valve.

So if its so easy just to loosen a single bolt with a 13mm wrench than why on earth did you and your son spend 4 hours removing the intake manifold??????LOL

Unfortunately, your way was the hard way, and I guess your just pissed off that someone figured out an easy and better way to do it, after you did yours. If you think my fix is cobbled than you just didn't look close enough at the pics and video. My fix looks stock if not better. I use a stock drivers side stainless steel tube, stock check valve and standard 5/8" heater hose. I mounted the passenger side check valve the exact same way the drivers side is mounted, so you say its, "cobbled"??? Upon inspection I bet GM Engineers would say to themselves, "Why didn't I think of that".

Your train of thought is bitter, antiquated and old school. The Corvette Forum is for people trying to help each other by sharing information on maintenance, repairs or modifying our Corvettes. Hell, most of the posts are about modifying & upgrading vettes with nonstock aftermarket parts, that must kill you. In your view all those people who design different cams, air intakes, use different wheel sizes etc... are all cobblers too??? I guess no one can do it better than GM huh? As a senior member you should know this and be a little more open minded.

PS. I guess I achieved, "balanced air flow" since I don't have the P1416 code anymore.

 

Was that your last edit, or are you still digging for more to build your case?

I'll wait awhile longer to respond.

 

I'll edit when the facts aren't right and I'm honest enough to admit it.

I guess you didn't read the original post at the top, "For those who are willing and comfortable taking the fuel rails and intake manifold off to replace the passenger side check valve this fix is not for you."

 

You don't have to take the fuel rails off, just one push-lock connector (2 on earlier cars) and its done. Fuel rails and injectors stay in place on the intake.

I also like my car to look as close to factory as it can. Running an extra piece of hose the long way does not look factory at all. The engine bay on these cars already has plenty of stuff going on, no need to add to it.

My P1416 error came on ONCE on a 10 year old car. Once I fixed it properly, it should be good for at least another 5 years.

 

I had the P1416 code and used the carb cleaner method a couple of years ago. Great fix, have not had a problem since with that code popping up. But that is a good workaround if people don't want to remove the intake. And I agree, that is how it should of come from the factory having the valve off the manifold like on the drivers side.

 

Arnie,
I'll take your word for it regarding the fuel rails and injectors. If you view the videos carefully you'll see that with my fix there are actually less parts or pieces than factory stock and less connection points. One could argue, less chances for air leaks? Also the engine bay doesn't gain nor does it lose any thing you're simply rerouting the passenger side line. If you consider the abandoned section of hose hidden and buried behind the intake manifold useful space than I won't argue with you on that.
My P1416 came on once in 10 years too but I still don't want to remove the intake manifold.

After you replaced the check valve did you bolt the new one down just like the original?
You don't have to answer that.
Arnie don't take my response in a negative way but I intentionally named this post, An Alternative Fix For The P1416 Code so people like yourself wouldn't waste their time reading it. I then stated in the body of the post, "For those who are willing and comfortable taking the fuel rails and intake manifold off to replace the passenger side check valve this fix is not for you."

This post is to help other vette owners, like myself, who don't want to remove the intake, who want to keep using check valves and not block them off and erase them from the computer, and who like the idea of improving the design of the air system so troubleshooting or replacing the passenger side check valve in the future would be a snap.
There are many other threads regarding the P1416 code and the standard way of replacing the passenger side check valve by removing the intake etc... so your comments are more suited to those threads.

And there are those threads that explain the cleaning method not replacing the check valve at all. Some say they had luck with it but most didn't. And the problem with the cleaning method is that not everyone will update the thread if their problem comes back and the cleaning method doesn't work anymore. I tried the cleaning method myself because its a chance at a simple and inexpensive fix. I don't have an air compressor to shoot the carb cleaner toward the check valve so I went to the local gas station and using their free air pump to inflate tires I opened my hood, disconnected the hose, sprayed a lot of carb cleaner in it and then blasted the cleaner towards the check valve. I reset the code and it stayed off for a week (warm weather, no cold mornings) but at that time I got the idea for the Alternative Fix and did that for the permanent fix.

So bottom line is that I'm just trying to help others and I'm not soliciting for negative comments. If forum members want to contribute I suggest that they post the following basic information...
Year of their vette?
How many miles when problem occured?
How did you replace the passenger side check valve(ex. did you remove the intake, did you take it to a mechanic, or did you do the alternative fix)?
If you fixed it yourself how long did it take you?
I don't think cleaning is solid information because like I said before they won't always update their situation leaving us to guess the outcome. If you cleaned it and it lasted a couple of years or longer maybe that would be good to include.
What did it cost you to fix? parts?
Did you have any problems fixing it yourself?
If you took it to a mechanic than what did they charge you?
If you took it to a mechanic did you wait for the repair or did you have to leave the vehicle overnite or for how many days?

I believe the contribution of this basic information will help others decide what to do with their same situation without negativity.


I'm adding the following link to the Corvette Forum Parts For Sale Section. I created this thread to be a central place where members can sell or buy specifically the C5 Drivers Side Emission Pipe#2. As you know many Corvette Forum Members remove the stock exhaust system for headers or they just want to get rid of the emission system by blocking off the emission tubes with block off plates then erasing them from the computer. If these people would like to sell their unneeded Drivers Side Emission Pipe#2 then those that want to do the Alternative Fix To The P1416 Code can buy them. Another reason for this thread is that the Emisssion Pipe#2 is very expensive to buy new.

Good Luck!

 

Your point is certainly understood, and well taken.

My opinions on the subject, however, are based on rock solid advice from some of the most trusted Forum Tech Contributors, like Bill Curlee and lucky131969.

You have provided a viable alternative solution, to a common problem, in a very well presented, and easy to understand manner.

 

do you know how to repair p0410 code?

 

Artty,
I understand that code P0410 regards the AIR SYSTEM and there are many experienced forum members who may be able to help you diagnose your problem. Type P0410 into the search box and you'll see all the threads that contain, "P0140" in red. I see a guy, Paul Wood, has had the same problem as you and then I see Bill Curlee explains a lot of stuff regarding that code too. Read all the threads including this one...
