I looked up the code P2203, my dealer caught it, google threw a few topics about it, apparently it is triggered by a faulty rpm sensor, which causes the car to go limp, no power, no boost, no gear changes.

I was wondering if anybody has any experience with this code?

Hulk

Are you cruising or wot when it goes into limp mode?

Kelvin07

Always at very low speeds triggers code p2203, never at high speeds.

Is that code related to the (speed sensor 3) gas pedal sensor..?

ZAYED,,

Kelvin07

I think so, it is about an rpm sensor.

The car goes into a sort of protection mode, I thought it was the SC, but my dealer says no, its either that sensor, or my gearbox or my tranny

Hulk

Yes it is but don't know if it's the pedal

2203 or 220B?

220B - The speed of Y3/6n2 or Y3/6n3 is too high.

It is referring to the speed sensors or rpm sensors as your dealer may call it.

Hulk

Conductor plate, if you cycle the key is it ok?

Kelvin07

It's in spanish, but I think you can see which one it is

If you repair this yourself, please POST PICS! I think you might have to replace the entire unit, but if you can simply repair the speed sensors COOL!

Kelvin07

The dealer is doing this

Hulk

Yes the entire unit and it's around 150$

You have to replace the whole conductor plate it is not very expensive 200 bucks

LOL, my mechanic tried to sell me one for $800 with labor.

Hulk

It takes about 1.5-2 hours, wow

Hmm.. I replaced my conductor plate before, It's pretty simple. But in the end I needed a new transmission anyway.

Kelvin07

Exactly, if cycle the key, it goes back to normal..

Kelvin07

Would this work on my CLS55?, I'd guess it's the same parts

cm60k

Yes sure it will work, all 722.6 are the same...

ZAYED,,

Now that you said if you cycle key it works again, it's conductor plate, buy that part and get it installed but don't do a trans flush, just make him do a refill of the fluid
