This morning my dear wife took the car to work. She noticed a severe bucking and engine light came on. I checked code and P0339 came up. I went to dealer and bought new cam sensor. Reset by disconnecting battery. Code did not come back and car runs fine. Could this be a cause for the 50 mph to 65 mph rubble I get under load? is there a procedure for install of the sensor in knowledgebase. I did search but not very successful.
P0339 points to crank sensor
P0339 Chrysler Crankshaft Position Sensor A Circuit Intermittent
IMO, intermittent crank would cause bucking
