I have an 04 sprinter and am dealing with a stall concern. Sometimes it will stall in 100 yards and somtimes it takes 50 miles. I can turn the key all the way off and then back on and the van starts and runs fine for a while and then will stall again. It stalled on me 15 times in a 3 mile distance on day. Is there any one that can help me with this concern. I know that this is a fuel injector B circuit code. I need to figure out how to diagnos this code. Is there any pim piont testss out there that I can follow. Any help would be greatly appretiated. Thanks.

Still need some help with the code. Sounds like I might have a wire chaffing problem. Is better to replace the whole engine harness?

So this must be a hard problem if there is nobody out there to even comment on my post. Looking for a pin point test and wire shematic for this code. Please help.

Did you try www.techauthority.com for wiring diagrams?

You might even find some useful diagnostic info/procedures www.startekinfo.com.

Besides the wiring, you may want to check the ignition switch.

Problem doesn't hurt to check these...

I wouldn't replace the entire wiring harness, because you could be replacing something that is not causing the problem. You need to narrow it down. It's also not an easy task even for the experience.

Btw, is that the only code that's being generated?

That code is not mentioned on the 2004 Service manual/CD.
Looking it up on MB's on-line service system, it has three entries:
[1] Fault in analog/digital conversion .: The actual value is not within the permissible range.
No further information available.
[2] Fault in analog/digital conversion .: The actual value is not within the permissible range.
No further information available.
[4] Fault in analog/digital conversion .: Current implausible
No further information available.

The usual "wire chafing" point is where the cable running over the top of your engine gets cut by the top heat shield edge as it starts to drop down in the rear.

Calling Doktor Andy's Sprinter Hotline is 412-366-6165.
good luck

Thanks for the replies I will check the resources you guys gave me and check the wire harness spots. What should I look for in te ignition switch. Yes this is the only code being generated.

What should I look for in te ignition switch.

The only thing you can do is to inspect the solder joints and trace where each wire goes to make sure it's not chaffing against metal.

Another thing you can do is to monitor the voltage off those terminals. If it's intermittent, maybe a bump to the ignition switch may give you bump on the voltage meter.

Thanks I have not yet had time to deal with this but I will let you guys know as soon as I look into it thanks again.

P2149 is injector voltage supply circuit open.

I would first take a look at the sockets/wiring to the injectors from ECM .
If anyone of the sockets are loose it will cause stalling/no start.

I have had quite a few reman'ed Dodge injectors of late that have caused similar driveability problems mostly caused by high voltage faults though (defective electrics).

A decent scanner might/should be able to locate which injector is causing the fault.

Hello my name is Serge I have a YouTube channel ZIMALETA How To Show & Unboxing and I help everybody but Sprinter problems I have the same problem right now and I've been trying to Chase it down I know this is the old post but I would like to help any other person here on Sprinter forms to find a solution for this problem trying to figure out this problem on my Sprinter I have replaced the ignition switch that immobilizer and the computer I know to many of you replacing ignition switch might make a lot of sense but you might wonder why other things on my channel right now I'm actually trying to find solution so far I have also replaced the fuel filter and for some reason the problem went away for a while but the problem has come back one week later after getting some fuel So it kind of seems bad fuel related but I kind of doubt it I do believe the problem is electrical so there might be some chafing involved so what I will do I'm going to trying to find where the wire is chafing and if I cannot find that I will replace the wiring harness because I do have an extra one so it's not really costing any money and all this other things I replaced I had those parts so I don't recommend somebody just to throw parts at it let me throw the parts of my sprinter and give you the solution that is the whole idea anyways so if the wiring harness will not solve the issue I will replace fuel injector number three possibly four and we will go from there I have many other ideas of what to do next currently I'm doing season two Mercedes sprinter videos currently I have close to 300 videos on my channel over 100 of them are Sprinter related I have easy playlist for everyone to find exactly what you're looking for I try to be very thorough and a lot of people appreciate it so please check my channel out currently I'm getting over 35,000 views per month

I have been driving Sprinter's for the past 10 years I had many breakdowns and I fix them all myself so I have a lot of experience and knowledge when it comes to dealing with Sprinter's through my own trial and error and headaches lots of research and hands on I have my own garage and Currently I have for Sprinter's and I make videos showing you guys each problem in giving you guys the solutions that I find those problems I think you guys will appreciate my channel ZIMALETA how to show & Unboxing

Might I suggest using an oscilloscope feature on scanner or hooked to an independent analytical tool to read what's going on.

Making or seeing waves here is the answer!

Welcome to the forum Serge ! I have watched your YouTube videos , very informative & useful !

There's a spot behind the fuel filter where the wiring harness is firmly tied to the engine block.
People on the forum have found that to be a chafe area, "fixed" by releasing the ties-downs and replacing them with something less constricting.

(if i can find a photo of the area, i'll post it here)

This ^. It could be as simple as the nuts holding the wires on to the injectors are loose. It's a straight shot from the injector to the ecm according to this schematic( http://imgur.com/a/8yXKm ), so follow it back to the ecm and then test resistance from the ecm connector pin all the way to the injector, while wiggling the harness.

As a last resort, replace the injector harness.

Welcome, Zimaleta, I've watched just about all your repair video's, learned a lot, 'preciate it.
