Test over. Everything was fine until check engine appear on dashboard. Car lost power. Check dtc with diag. P2641 in error code memory. What is wrong?

You are in right, just disconnected diff pressure sensor but not temp. sensor. I"ll do it. Second testing phase underway.
By the way, about what is P2641 DTC?

After long time test same problem, DTC P2641-Exhaust Gas Pressure Sensor, car goes to limp mode.
Diff. and temp. pressure sensors disconnected.
Change back pressure sensor, same thing.
Ok, make some tests, disconnect back pressure sensor, new DTC appear P2089- Back Pressure Sensor , so P2641 is not related to back presser sensor.
What is wrong?

t's a bit confusing.
P2641-Exhaust Gas Pressure Sensor.
P2089- Back Pressure Sensor.
Car is friend of mine, he work with delphi-autocom diag, not with DAS or KTS.
Never mind.
Anyway to remove DTC P2641 to try.
And thank you for your effort.

Simple removing of this DTC will not solve the Limp Mode.
You must to find the reason and resolve the problem!
