Hi...

I have a peugeot 406 2.2 from 2000 (the TS4).

Recently the engine malfunction alarm went on in my dashboard and the engine periodically runs on 3 cylinders.
I've got a OBD reader which showed the code P0202 Cylinder 2 injector circuit malfunction/open...

So i have replaced the injector for cylinder 2, however the fault is still there and the engine bad.
Do you have any suggestions what might cause this problem?

I've also cleaned every Ground clamps that could be related according to the Haynes manual and checked the connections to the injectors also with a DVOM.

Is there anyone with a clue, because right now i have no idea what else could case this problem.

If it is an open circuit, then possibly a bad connection somewhere in the wiring. Check multiplugs etc, and if you can get a NOID lamp, try plugging that in. That will show you if you are getting current and pulses.
