Question
wheres it located

Answer
John; HI  I do not know what motor so , it is in the area of the camshaft at the front end of motor ,  you can get a photo of it at the local library in a tech book .and it should have a step by step - how to do in the book also,but just because the computer showed cam sensor it could be a few differnt things that is wrong with it so it must be looked at to see what is broken or worn out.
