I think I need to replace a cam sensor on my mom's 1992 Toronado Trofeo with the 3800 motor. Where is the cam sensor located? And whats the procedure for replacing it.. Also, there are 2 parts listed at Advance for the code that came up, it can either mean a cam position sensor and/or a crank postion sensor. I can't remember the code number that came up, but I'll look for the ticket.. What you guys think??
