Default What's the CODE skinny on P2511 or 2511

Okay,

so I have 2006 long and tall sprinter with 162,000 hwy mile on it. Just replaced the transmission last week with one from silver star in Norman, OK. I put 500 miles on it last week after the install and the trans was good but did have the RSN

Just did 1000 miles; and half coming back was in the limp mode. So with my DAD system I read the code on sprinter and get a P2511 Left EGS Positioner...thats it for codes. So now I'm thinking some sort of EGR code. And when I search this forum I see a ton about this code and how it is a EGR code.

So while I'm on the road I get out my "Complete Sprinter Fault Code Guide Volume 1 2000-2006" North American Edition by Eric J Ord and the P2511 code is a and I qoute
" Torque converter lockup clutch has excessive power consumption"

But if I look up the code without the p and just 2511 I see a "Exhaust gas recirulation positoner"

Anyhow I find it weird on this forum that most if not all theads with the p2511 are all EGR codes. Is my book wrong? I was thinking that my transmission was the trouble because I replaced it last week and the code I read but as I search around everyone is talking EGR stuff.

I'm sure I left more questions than ansewers as I am far from a mechanic. But I carry the DAD on the road with me so I don't get hosed by a dealership if I'm broke down in there shop.

I think my books wrong but I did just put in the remaned transmission??? What gives?

Got home in the dark and have not looked under the hood to see what I see

Thanks in advance

The DAD companion Sprinter Fault Code Guide is correct. The mistake you are making is not matching the fault code number with the specific module you found the code in.

For instance, 2511 is a MBenz assigned code number but it refers to 2 very different faults if found in the ECM or TCM. That number is used in both those modules and is assigned to 2 very different faults. Which module did you find it in?

Also, be sure you refer to your correct Engine module type in the fault guide. CDI2 is the '01-'03 Engine module version and CDI3 is the 647 version ECM used in '04-'06.

Thanks Andy, I thought you would have the info on this. And it does make sense now as the code is coming from the ECM for the CD13 for my 2006.

I'm off to do some trouble shooting.

Best regards,

Hello,
I have the same code and LHM. "P2511 Left EGS Positioner.." There are no codes under the TCM. I cycled the EGR and seems to work fine. If I try to clear the code with the engine running it will not clear.

Any suggestions?

Thanks.

Sven

I suggest carefully inspecting the connectors at both end of the engine harness, testing the 3 wires for continuity, short to ground, short to +, and finally testing with a known good EGR valve.

Thanks for your reply Andy!

I did run the EGR test feature once more. Also, it did change the values, it did not change the engine sound, which I normally hear when doing that test. Also there is a loud shrill squeaking sound for about 15 seconds after I shut down the engine. It clearly comes from the EGR valve. I will remove it tomorrow for further inspection and will report back.

Okay, lremoved the EGR valve and cleaned it. It was sticking a litle bit. I also checked the harness and it is okay. I checked the continuity of all three wires. From the right looking at the bottom of the plug, there is one unused position , next is ground, then 12V , and the last one has 3V, with ignition ON. Cross reading shows no continuity - so that's good. When actuating the EGR valve with DAD it works fine now. Still I get this funky error code. Why does it say left "LEFT EGS POSITIONER" and we are lookoing at an EGR failure, even so I do think as well that I have an EGR failure? When I was test driving I can reset the CDI engine faults and get out of LHM for a short time.
So what is next - buy a new EGR valve?

Thanks for any help up front!!

You might consider trying the EGR override circuit (Colorado_Al found this and has tested it) and see if it eliminates the error (the EGR is effectively simulated as far as the ECU is concerned, and no longer needs to be plugged in).

See:
http://sprinter-source.com/forum/showthread.php?t=19224

If the error goes away, then you probably have a bad EGR valve, or something that feeds it ECU info (like the MAF) may have some issue.

Yes thank you, l will very likely modify, but don't have time the next 2weeks. I just do not like this strange error message, and would like to know why it says what it says. The EGR mod is definetly the way to go if the valve is bad.
Thanks for you reply.
