Hello and welcome to Just Answer!
This code can be caused by either the cam or crank sensor, but the most common is the cam sensor. The cam sensor is located on the rear side of the cylinder head opposite side of the timing belt. The sensor is held onto the cylinder head with two 10mm head bolts. The connector faces down and has a red locking tab that you have to slide out till it stops. The squeeze the connector release tab and pull the connector off.
I hope this helps, let me know!
