After stalking this website for the past year, I've broken down and become a member. I'm totally out of ideas and looking for guidance. Will post to the appropriate boards when allowed. Bought a 06 Commander Hemi in January of last year and have had nothing but problems since. I have been battling engine codes P061C, P0344, and P2072 without end. Rebuilt ECM, new EGR valve, new spark plugs, 2 new cam sensors and no help yet. Local Chrysler dealership says they can't figure anything out and now the local mechanic that I had been working with is out of ideas. Summary of problem is that it randomly jerks and dies - cruising down the road doing my own thing and the stupid thing just shuts off - then dashboard lights up with the Lightning bolt of doom and my traction control light. I'm praying that someone here knows the answers or at least where I should look next. The thing runs and shifts fine - until it slams and shuts off - completely randomly.
Welcome to the forum @brentswan54
I'm sure we have guys here that can help you get it sorted out;
First thing I'd ask you is, what kind of spark plugs did you use when you replaced them?
Hemi's are pretty finicky if you don't use the factory recommended spark plugs.
The fact that your local Chrysler Dealership is telling you that they can't figure anything out with all of the diagnostic equipment they have at their disposal is pretty ridiculous.
You might consider searching online for a more reputable dealership.
Here is what I was able to dig up:
P0344 is Camshaft Position Sensor A Circuit Intermittent (Bank 1 or Single Sensor)
P061C: Internal Control Module Engine RPM Performance
Internal control module monitoring processors are responsible for various controller self-test duties and overall internal control module accountability. Engine RPM calculation system input and output signals are subject to self-test and are monitored constantly by the PCM and other related controllers. The transmission control module (TCM), traction control module (TCSM), and other controllers are subject to interaction with the engine RPM monitoring system.
Engine RPM is monitored (by the PCM and other controllers) using input signals from the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor/s. Desired engine RPM is programmed into the PCM and other controllers. Actual RPM is calculated using input data from the CKP and CMP sensors, as well as the throttle position sensor (TPS), and other engine and transmission sensors. Desired RPM is then compared with actual RPM.
Whenever the ignition is on and the PCM is energized, internal engine RPM monitoring self-tests are initiated. In addition to running internal controller self-tests, the controller area network (CAN) also compares signals from each individual module to ensure that all controllers are functioning properly. These tests are performed simultaneously.
If the PCM detects an internal error in desired engine RPM and actual RPM (which exceeds the maximum allowable threshold), a code P061C will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple ignition cycles (with a failure) may be required for MIL illumination.
P2072: OBD-II Code P2072 is defined as a Throttle Actuator Control System - Ice Blockage
I hope this helps you out a bit.
