Hi, I want to share some information about ETC, this is what hapened to me.
My Patriot (2007 2.4 limited CVT) have same symptoms, start at last january, ETC light flashing when accelerating hard, and now finally last month engine goes to "limp" mode, no revs above 2000 rpm. No computer resets etc does any good. Also ESP light turns on.
I read these forums, and raising knowledge of my car.
I dissemble air intake manifold, and found "butterfly" valve there. I was 100% sure that it's the cause of problem. But I don't have spareparts here, or Chrysler's computer/software to relearn new valve positions. So I have to take my Pat to local Jeep service.
They check engine codes (was none), also they stated that ETC light might maybe leave some codes to memory. Possible causes was engine computer, throttlevalve, or wiring. Then they finally replace that valve, and now my car is working fine, no ETC flashes or nothing...
This episode costs to me total about 600 euros here in Finland, and I know that throttlevalve costs about 140$ in America, so I think that I have been robbed!
Finland is country for rich people
