Did this just start since the tune-up? Is this the only code that was found? Have any new codes set since you have been trying to use the vehicle?
I attached a pic below. The code, P0015, is specific to the exhaust cam sensor indicating the timing is extremely retarded. In other words, it's running behind. Is this the sensor you replaced? Are you certain it is fully seated and connected?
Let me know. Also, if possible, record the engine cranking and running and upload it so I can hear it.
See pic below.
