The same thing is going on with my 2011 jeep patriot 2.0 . I just bought it back in July 2022. At first the MIL and ESC light came on here and there and when I cut the car off and back on it would go away. But now it is on 24/7 and stuck in limp mode which is dangerous as he'll. It won't go over 3000 rpms and is running very very sluggish.. I do have a warranty so I took it to the dealership and they replaced the alternator and the ac compressor and when I first got it home it ran like a whole new car but a few hours later the same lights came on. It is reading p0340 code which is the camshaft position sensor. Our jeep has 2 so I replaced both but it still is going into limp mode. I don't know what to do cause it is almost impossible to keep driving it this way plus I don't wanna mess up anything further. All my mechanic friends are all telling me they have no idea what's going on. Someone please give me some feedback cause I dunno what to do anymore. Thanks oh also my jeep has around 207,000 miles on it.

Wiring / connectors can cause this, or a failing PCM.

2016 Patriot engine camshaft broke

My son's 2016 patriot he purchased new, was driving the other day and it quit. he got it home but now it doesn't start. Had it towed to local dealer as it was suppose to be under warranty. They found a broken camshaft (their diagnosis) and want o replace the motor for $8000. and it isn't under...

It would also help if they have a scanner that can display or graph live data from the camshaft position sensors to see if the proper signal is there.
