General P0339 P0335 code for 2015 Fiat 500 POP

[ernieb1986]

I hooked up a scanner tool to the obd II connection and these codes popped up. It’s calling for a camshaft sensor and crankshaft sensor. The car is having trouble starting you have to hold the key down for it to finally start and the acceleration is weak or takes it awhile to get up to speed and seems as it is in limp mode. I did a throttle body position sensor relearn and it pass. Anyone have an issue with this? I’m hoping I don’t have to drop the transmission.
