Location of ECM on 2004 Chrysler Town and Country minivan 3.8 liter engine.

What is your question?

Minivan will start but takes a long time to do so. Also, will idle after starting but will not go over 3000rpm without missing very badly. Getting code saying crankshaft position sensor circuit A malfunction. Changed parts by the code crankshaft position sensor, camshaft position sensor, idle control valve, throttle position sensor but nothing changed Now suspect the ECM unit but unsure where it is. Any help would be appreciated. Thanks, John
