Camshaft position sensor

See picture. There are two in diagram.

Do not know the code so I do not know which one is bad. I would do them both.

First thing you have to do is check the VTC solenoid to see if it is working or has a plugged screen, then have a mechanic check for a stretched timing chain. After replacing both sensors then have a mechanic put them in sync with the crank sensor as this must be done with a scanner. It is like setting timing but you need a scanner to do it.
