P0410 code SOLVED ! ! ! ! !

mrmuzic · 05-26-2009, 02:51 PM

I was getting a PO410 code popping up and sometime even getting the 17? and another 17? code to. The 17? codes wound up being hoses that were popping off that were associated with the charcoal canister (gas return system) so that vapors don't vent to the atmosphere.

The P0410 error code was more involved. I would reset the code and monitor when the code would re-appear. It was at intervals of 200 miles. I went on the MB forums and read as much as I could about this code and things that other people had tried. The cheapest thing was adding a Lucas additive that's available at WalMart for about $10. You get about 4-5 treatments with the container. The first treatment that I did which is nothing more than adding 3oz to a full tank brought the intervals up to 260 miles. I thendid another treatment and it brought it up to 330 miles. Well I am now on my 4 treatment and well over 400 miles and NO P0410 error code.

This is a VERY complex error code which can get VERYexpensive to repair if you bring it to MB. All I know is that my gas mileage has gotten better and the intervals have lessened considerably. Hopefully after 1 more bottle of Lucas I wont be getting any error codes despite the mileage !

Other than I think you're possibly correcting the symptom rather than the sickness, I would also be wary about running that much Lucas through your engine (and eventually vapor to your cats)- the E manual specifically states NOT to use any fuel additives beyond typical pump additives due to sensitive cats- anyway, good luck!

I just had the same code pop up on me this am............at 200 miles?? what is the problem???

I will check to see if the pump is working tomorrow am...........then check the fuse..........and hose's...........anything else???

HELP!!!!!!

the code clearing had not thing to do with what you put in the fuel.The sec air pump comes on at start up to inject added oxygen into the exhaust so that the cats fire up in under 2 minutes.The P0410 will return. At least until you fix the secondary air issue. Lucas will not do it. P0410 also has no affect on mpg.The air pump comes on for a few minutes when the engine is cold(you can hear it pumping along when the engine is at high idle on cold start and then it goes off.
The obd2 system checks it periodically for proper function.
Check vac lines to it.Disconnect the feed lines to the exhaust and spray with crc cleaner, check the check valve. It is not a circuit malfunction or anything that a fuel additive will repair.
In colder months the check valve will fill with moisture,The weather has warmed up and the code is gone,it will return when the weather gets cold.Cheap part,replace it before it damages the air pump,which ain't so cheap.

Thanks for the info Ohlord...............I will check the lines and check valve, also spray cleaner as you sugested.

How do you know if the check valve is bad?........other then looking at it? would it be a wise choice to just replace?? 12 yr old car??

This code has been an issue for me for about a year. The first time, I noticed that the vacuum lines to the check valves were damaged and replaced them. However, the code never went away. I suspect that because the check valves never actuated, exhaust debris built up on the channels and plugged them.

This morning, I removed the check valves and checked them for functionality (they both open at about 11 in.Hg). With the valves off the car, I ran the engine and noticed that the driver side reeds were flapping, indicating that they were open. The ones on the passenger side remained static, which meant they were blocked.

I tried to remove the valve housing stem and attempt to pry the blockage loose, but after removing the torx bolt, the stem would still not budge (it looks to be integrated to the manifold). I tried to force high-pressure air through the check valve (open, of course) but the channel appears completely sealed.

The error did clear itself when I was running without the check valves on, but I think the only real way for me to resolve this is to somehow clean the passenger side channel. Also used solvent cleaner but without an opening, it didn't really help.

I have had the problem for quite sometime. Where are these feed lines located, so that I can check them?
