So since it has gotten warmer up here in the Northeast which means not below freezing and into the teens the 2010 2.4 with 176K is showing 12.3 on the plug in lighter voltmeter and starts. Since voltage production and transmission cycles are controlled by the PCM I HAVE to assume that components within may have microfractures in the soldering, a temperature varying component failure, or corrosion in the harness and wiring. Anyone take apart the PCM shell to check for these kind of conditions? They put the battery sensor in in 2011 models so I think they were aware of issues here, and I have the block heater and a trickle charger installed in the car and a jump pack in the tool kit. Need to go to the dealer and try to get some info out of their system and techs maybe hook their expensive SnapOn code reader/laptop to check for wiring shorts or variances from spec. Runs fine but not sure if I will make it look pretty and get rid of it as its FWD but there arent many cars out there at this point that would work but thats the fun of it And figuring out the reason for that dang parasite. .

 

There is still the issue the voltage at jump points is 12.4 the voltage inside on a digital voltmeter plugged into the lighter socket could be as low as 10.3. It wont start then but jumppack starts it. Looking at TIPM rebuild next.
