Ls cam sensor

[Wiseone]

I did a DOD delete on my 2007 Silverado. The cam gear is hitting the cam sensor. What did I do wrong?

Could be that you got the wrong part number sensor in there. Did this engine come out of a GMT-800, or the 900 series truck? There's a HUGE difference between the 2, and they do not interchange.

 

Another possibility is a poorly manufactured aftermarket sensor was built to the wrong specs.

I got the GM sensor and it’s the same exact size. I am wondering if there is another size. I used the single bolt GM cam. But that motor had the sensor on the side of the block. Cam shouldn’t be longer should it?!?

 The GMT-900 used a Gen IV engine - that cam sensor is in the timing cover. The earlier generation is in the back of the block. I'm fairly certain the part numbers between the 2 are different.

This one is in the cover. I put the GM one in and slowly turned. And it still hits the sensor. Can the cam plate go on backwards?

I don't know the intricate details of these engines, since it's easier for me and cheaper for the customer to have a new engine installed when they fail. I do know that the covers on these engines - both the timing and rear main - require an alignment tool to re-install if removed - that would most certainly cause the problem if that wasn't done.

Well I did use the tool on the front cover, looks like I get to do it again!!

Make sure you have the correct part number sensor before you go pulling it all apart again. Could just be the wrong sensor. I would get the number off the old one and reference that.
