Evan Purple240zt Posted March 31, 2008 Share Posted March 31, 2008 First and foremost, pay attention to what your saying. You mention cam AND crank. Which is it? I am assuming the tab is broken off the cam that drives your CAS. New exhaust cam time. Evan Quote Link to comment Share on other sites More sharing options...
voltron_boi Posted March 31, 2008 Author Share Posted March 31, 2008 so your saying if i dont replace it, it will not start the car rite. Quote Link to comment Share on other sites More sharing options...
Careless Posted March 31, 2008 Share Posted March 31, 2008 cam angle is used as a reference for the computer to know how many degrees of rotation have passed since the last or first fire of a cylinder. since the cam angle/valve opening and closing time is somewhat proportional to when a spark plug should fire, if the cam sensor does not turn, the ignition will not know when to fire, or it will not advance or retard the system automatically to save your engine from disaster. in short, yeah. you need a new one.

If the cam is indeed broken, you're likely stuck with replacing it. A picture would help greatly here. so your saying if i dont replace it, it will not start the car rite. That sensor is the single most critical sensor in the entire EFI system. There is no way to bypass it (with the stock ECU). It must be in proper working order. P.S. please fix your shift key. First and foremost, pay attention to what your saying. You mention cam AND crank. Which is it? Evan, Nissan calls that sensor a "crank angle sensor" even though it is, in fact, a cam angle sensor.

stony Posted March 31, 2008 Share Posted March 31, 2008 You can find them on ebay every now and again. Or if you have a friend you can get them any day of the week off of japan yahoo. The sensor that is. Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted March 31, 2008 Share Posted March 31, 2008 I have a spare sensor if you need it. Spare cam on the other hand, not so much. Quote Link to comment Share on other sites More sharing options...

Evan Purple240zt Posted March 31, 2008 Share Posted March 31, 2008 Before he edited the post, I was unsure of what broke. Also, make sure you get the right exhaust cam. There IS a difference between the s1 and s2 sensors and cams! You may want to toss a WTB up on nicoclub.com in the RB area. I am sure someone there has spare cams.
