94 E420 - Code #11 on electronic accelerator control (EA) module - PeachParts Mercedes-Benz Forum

Folks,

Using the reader that I built some time ago, I decided to check to see if I had any codes set on my vehicle. I checked them a long time ago and cleared them all out, but one of them came back again. Specifically, it is code #11 on the electronic accelerator control (EA) module.

JimF has a great site and a page that explains this module:

http://pages.prodigy.net/jforgione/MB_EA.html

According his page as well as the earlier post which I mentioned this code, here is the definitioni of code #11 for that module:

11- Closed Throttle recognition signal to engine control module, LH-SFI. Fuel safety shut-off to engine control module, LH-SFI

Can anyone tell me what I can look in order to determine that cause of this code?

Thanks!

any codes in the DM??

If you look at Menu#1 at the block diagram, you'll see a connection from the EA (N4/1) to the CTP switch, S29/3 (called the Pedal Force Recognition Switch) and that maybe bad or making a bad/intermittant connection? Probably 'fried' due to engine heat.

Let us know.

None.

I'll check that out. Any idea where the CTP and Pedal Force Recognition switch reside (or are those one in the same)?

Also, here is what alldata says... not sure exactly how to read it.

There is an outside chance I did not properly clear this code out the first time.... so I'll just monitor it for a while and see if it comes back.

Here's another picture

Well, My code 11 is back. I only noticed it because my check engine light came on and I decided to check for codes on ALL of the modules. Check engine light was due to a code #26.

So, the only codes currently on my vehicle are DM #26 and this EA/ICS/CC code of #11. Are they related? What exactly is code #11? I posted the text in a previous post above.

I have no symptoms regarding this code #11. I read your post, but don't see the relevance to my problem. Interesting though, and I'll keep it in mind.

What is the difference between EZL and DI??

DI/EZL are the same both referring to the Ignition Control Module. It control your timing, injectors, and also take information from your knock & crank sensor while communicating with your other computer modules.

On the accelerator pedal is a micro-switch (S29/3-feeds EA direct), this switch "confirms" that the throttle (M16/) is in the idle position. I believe if it has an intermittent connection your ASR light would come on and the ASR system might go into limp home mode. I may be wrong about the failure characteristics. A small investment in this micro-switch may be worth it to see if it will cure your code 11.
