A year or so ago, I went down the rabbit hole with that error.. started showing up after dodge replaced the oil cooler. Checked all connections, replaced the throttle body.. then started getting oil pressure sensor errors. Turns out dodge did not replace sensors, just swapped to new cooler... but aside... they stripped out two bolt holes on the lower intake so I was pulling air.. bad seal. Replaced lower intake so the upper intake seated properly, new gaskets and it went away.

Probably not far off from failing. My jeeps oil pressure sensor failed at 200,000 km

Going to check it out when I get a chance.

I might of found something here

So I made and open point from the pcm to the main harness connector where the pink/yellow wiring which i lost the 5v on which is connected to the tps ops and a few other sensors.

From the pcm to that connector I got 107 ohms. There is still about 2 feet of tapped up wires to unravel and look for a short though

Whats strange is that I read 2.6 ohms from the tps to the pcm before the no start happened
