You can get a used PCM on Ebay and reprogrammed to your VIN, that way you eliminate your doubt about the PCM.

Did you use OEM sensors? Most of the sensors in the Journey are hall effect and no OEM could give you headaches.

If you decide to check the timing belt, here is the infotimingbelt.rar

This all info I found for the codes you having, it may help you. P0172.pdf P0175.pdf

Most of the problems with wiring is at the connectors, they oxidized or the pins get loose connections due to metal fatigue, clean the connectors witlh electrical contact cleaner, it may fix the proble. Once I have a Dodge Caravan that the dashboaard ramdonly dies and fixed it for good resoldering all the crimp wires that goes from the dashboard to the PCM.

The fix in my 2.4 was the intake gasket, read my post here: https://www.dodgejourneyforum.com/topic/12196-p2173-high-airflowvacuum-leak-detected-fixed/

I had the P2173, red lightning bolt and the ESC light 3 years ago, the fix was to change the intake manifold gasket, you can try in yours it may fix the problem and is inexpensive and easy repair.

Try cleaning the ABS connector with an electrical cleaner spray can, always remove the negative cable from the battery, remove the ABS connector module and spray the male and female connector with good amount of cleaner. I use the WD40 contact cleaner brand.

This one can be removed, I put the same on the Brakes section, so people can find it easy

I have the C2200 Anti-Lock Brake Module Internal Failure for a while, the code use to return after 2 weeks of clearing codes, recall was done few years ago and most of the fix is to replace the ABS module, I fixed mine just connecting all the grounds in one single post (see attached picture and recall) It have been one year since the fix and the C2200 has no returned.

The head gasket is below the valve cover (the one in the picture) has holes for the oil and water circulation and have the intake and exhaust valves

Is a 2.4 engine? if Yes, it sound like bad idler pulley or alternator decoupling pulley. Remove the serpentine belt and start the engine, if noise is gone then you know is any of the 2 choices.

Try to clean the AC condenser fins with a pressure washer, make sure there is no debris in the condenser obstructing the air flow to the radiator.

If it goes to 2000 RPM for 2 or 3 seconds is probably OK, if it last more than 30 seconds I will recommend you to change the intake manifold gasket as those engines with the plastic intake tend to leak.
