[QUOTE="Chris, post: 425133, member: 1"] [B][SIZE=18px]P0344 Possible Causes[/SIZE][/B] [LIST] [*]Defective Camshaft Position Sensor [*]Faulty or corroded Camshaft Position Sensor wiring or connections [*]Defective Crankshaft Position Sensor [*]Rough running/misfiring Engine [*]Stretched Timing Chain or Timing Belt [*]Jumped Timing Chain or Belt [*]Metallic and/or rattling engine noises. [/LIST] [B][SIZE=18px]P0116[/SIZE][B][SIZE=18px] Possible Causes[/SIZE][/B][/B] [LIST] [*]Defective Engine Coolant Temperature Sensor [*]Rusty and/or corroded Engine Coolant [*]Faulty or corroded Engine Coolant Temperature wiring or connections [/LIST] Based on your description, I would say the camshaft position sensor is most likely failing. I believe in the factory service manual there is a procedure to test the CPS with a multimeter and determine whether it is bad or not, so that is 100% where I would start. If the CPS is faulty, make 100% certain to replace it with an OE Mopar sensor, as aftermarket brands will give you trouble. As for the P0116 code, it sounds like your engine coolant temperature sensor may be bad, the wiring, or the coolant really needs to be changed. Take your radiator cap off, inspect the coolant. What does it look like? Is the radiator completely full? Inspect the wiring going to the coolant temp sensor and see what it looks like as well. If you don't feel comfortable doing any of this, take it to a mechanic. [/QUOTE]
