OKay i have removed the cam sproket cover and now i made shure that engine was at top dead center and now i need to set up the cam angle sensor to be set near correct to have the engine start. Now where do i line up the marks on crank angle sencor and the sproket. I have no idea of what marks on both the cam and the sensor, or is it the mark on the cover? I know i am TDC and the piston number 1 is at the top. so plz mark my pictures(photoshop) and show me what marks i have to line up on either peices. Also when setting up for intial timing is the piston sapose to be at the top of the cylender or the bottom when set at TDC, since there are 2 TDC one where the piston is at top and when the piston is at bottom, It is a Ca18det HEEEEEELLLLLLLLLLPPPPPPPPPPP.

Download a free copy of the Factory Service Manual from this website for a CA18DET. It will tell you what base timing is.

1. tdc means top dead center. that means the piston should be at the top of its stroke.

2. its not a cam angle sensor. its a crank angle sensor. there's a big difference... and the only thing the FSM says about that is to install it according to the marks that were made when you uninstalled it (after setting the engine to #1 TDC). i hope you were paying attention when you took it out, because the FSM states on EM-10 that you need to mark the position of the sensor so that when you reinstall it on page EM13, you know how to put it back in...
