I have a 2007 chrysler aspen with the 5.7l. After getting it we replaced the plugs all 16 with e3s, all new coil plug boots and 1 coil pack because it was throwing up a code for misfire. Ran fine for a couple mths then oil light came on got code for oil pressure sensor . Changed that along with having flow master super 44 put on it. Drove a week and was raining pulled into parking lot and car just died and wouldn't restart. Got crankshaft position sensor code along with check engine light and lightning bolt and anti skid lights on. Towed it home changed cps and it will start rpms jump up and down then stalls. Won't run for more than 20 seconds. No gas pedal at all to try and keep it running. Have changed egr valve, camshaft position sensor, ignition switch, cleaned throttle body but no change. Code p3449 and p0522 check engine light and lightning bolt still on. Anybody have any ideas?

 

P3449 is the MDS solenoid for cylinder 7. These solenoids going bad seem to be a common issue. I myself get random P3441 which is cylinder 6. Although it doesn't kill the engine. Just disables fuel saver mode.

The P0522 however, is low oil pressure or oil pressure sensor circuit too low. Now you already changed the sensor so it could possible be a bad oil pump. Then again, you mentioned this last mishap happened while it was raining. I've seen several reports from others who say things go crazy when it rains which means water is getting somewhere it's not suppose to. In this case, possible the PCM. From what I've read, it's suppose to be in the engine compartment mounted to the drivers fender. Based on the fact that you have so many different errors going on, I would start looking there.

 

finally figured out the issue after many trial and errors. the shop who replaced my oil pressure sensor used a non mopar part so after a couple weeks it caused all kinds of electrical issues with the throttle body so it stayed in limp mode. replaced it with mopar and it's running perfect. lesson learned mopar only when replacing this part.
