I have a 2008 Caliber SRT4 with 179,000 miles and I recently noticed the P0017 engine code a few weeks ago. Since then I have replaced all camshaft and crankshaft sensors, changed the oil viscosity, and cleared the codes multiple times. Even after all of this, the car will not rev past 4K rpm in any gear and it seems to fall off once it reaches that point. All boost drops and the rpm’s stay at 4K and the car stops accelerating. I don’t know what else to do to fix this problem. Does anyone have any advice, suggestions etc? Thanks!
