Car Studdering

#1
Hello! 2009 LE that is throwing code P0117. Replaced the Engine Coolant Temperature sensor but still getting same code for low input voltage from the ECM. Anyone had to replace the ECM due to the ECT? New coil packs were installed on all cylinders in attempts to solve the stuttering at idle. Also no avail...fuel filter is next unless one of you points me in another direction. Thanks for the assist.
