location of camshaft sensor

This is the exact location of the camshaft sensor for the vehicle you provided. It is held on by a 10mm bolt. Once the connector is disconnected and the bolt is removed, you may need a set of pliers to work the camshaft sensor side to side in order to get it to break loose from its grip on the head assembly. Best of luck!

Thanks. I am having great difficulty removing the 10mm bolt. Is there a special trick? I have tried using 10mm socket but no joy.

Try spraying a penetrating lubricant like PB Blaster or Freeze Off. It will help at attacking the corrosion and may break it loose enough to break free.

Try using an extension on the socket so it will reach down further. Here is a guide and a diagram (below) that should help.
