I have a 2005 Jeep Liberty 3.7L. im almost at 50k milestone right now. my wife took the jeep to work today and she stated that when she was pulling up to a light to stop, she felt the engine that is trying to stall then the CEL started blinking. She had to press the gas to keep it running to get to work since it was a block away from where she was.

i have the 5 following codes showed up after reading some posts. i would like to know where i could get the parts via online if possible?

P0300 Random/Multiple Cylinder Misfire Detected

P0335 Crankshaft Position Sensor A Circuit Malfunction

P0339 Crankshaft Position Sensor A Circuit Intermittent

P0522 Engine Oil Pressure Sensor/Switch Circuit Low Voltage

P0839 Four Wheel Drive (4WD) Switch Circuit High

ive done my research and wanted to know whats the best fix for those? I want to avoid the dealership if possible with those codes throwing at me.

I'm just taking a stab tbh.. but a bad crank sensor can cause the misfire, the almost knocking off/stalling can cause the low oil pressure

but add in the 4wd circuit and it more sounds like the ECM going bad?

try autozone or advance, i think it's about 30 bucks

it's on the front near the top of the drivers side head

i called autozone and they have duralast camshaft position sensor, is it any good? thats the only thing they have in stock for the jeep. Im not sure if duralast is an good manufacturer so asking for some tips from you guys?

I personally have never had a problem with duralast

EXCEPT their brake pads lol

but everything else, electronic and minor mechanical other than brake pads i've R&R'ed and gone on about my business and never had a problem from the part

Something's def weird now my cel is gone and there is no codes anymore. What can cause this to happen?

3 engine cycles from the last detection will clear CEL
Codes are stored in a memory that you need dealer type equipment to read

does it still have the problem running?
