    That should have said ECU.



    What exactly are you looking for?



    You have all the codes listed, and their meanings.



    It is likely all those problems stem from a faulty computer. Unplug it and re-plug to make sure the connection is tight.



    Your next course of action is to inspect the wiring for the injectors.



    Since they are 2,4, and 6 - it is likely the control circuit malfunctioning.



    CLICK HERE for a good tech paper.



    REASONS for the DTCs:

    Autoshut relay output circut open(no 12V to injectors)
    Defective injector
    Inj Control CKT wiring harness Intermittent defect
    Inj Control CKT wiring harness observable defect
    Injector Drivers circuit Open
    Injector Drivers circuit shorted to ground
    PCM defective


    If your wires that go from the injector to the PCM and pinched somewhere and are grounding, this will cause the injectors to be operated longer than usual and ruin the injector



    Thanks!

    P0601 OBD-II Trouble Code
    Technical Description
    Internal Control Module Memory Check Sum Error

    What does that mean?
    Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.



    FB.init("dd7d9e9681341cde77587bc6a2029f6f");


    OBD-Codes.com on Facebook

    Symptoms
    Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

    Causes
    A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

    Possible Solutions
    With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

    Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

First time verify & repair the injectors supply wires for cyl.2, 3, 4, and 6. If injectors supply wires are OK, then replace all engine injectors. The Engine Control Module will be the last piece out of order. After wires reparation & injectors replacement (only if necessary), you must erase all errors from Engine Control Module internal memory using a diagnostic scantool connected to the data link connector of the car before engine cranking.

P0601, and p0622


P0622 is "Generator field 'F' control circuit malfunction"- your alternator has a circuit malfunction in the voltage regulator function. You need to have the charging system checked. It may be a wiring problem in the circuit to the alternator. A shop needs to test it out.
P0601 is "Internal control module memory check sum error"- I have no idea what that means, but is probably set because the charging system has a malfunction, and the result may be memory loss in the control module when the alternator acts up. Have the 0622 fixed, erase the codes, and see if the 0601 returns. That is what I would do, anyway.

Recently my check engine light came on and I did a diagnostic to find a P0607 error to appear. The code had read something about a power train control module. I will probably end up taking my car into the...


P0601 Internal Control Module Memory Check Sum Error
P0602 Control Module Programming Error
P0603 Internal Control Module Keep Alive Memory (KAM) Error
P0604 Internal Control Module Random Access Memory (RAM) Error
P0605 Internal Control Module Read Only Memory (ROM) Error
P0606 ECM/PCM Processor
P0607 Control Module Performance
P0608 Control Module VSS Output "A"
P0609 Control Module VSS Output "B"
P0610 Control Module Vehicle Options Error
The p0607 error says Control Module Performance. It has something to do with the Control Module for the powertrain as you indicated. But, you may be able to take your car to a transmission shop to alleviate the problem using a transmission expert.

I don't think that it doesn't have anything to do with the engine, itself, even though it's listed under a driveability related code.

Good luck on this repair.
