ls7 cam in a Lq4 CEL I just got my lexus sc600 up and running yesterday. only problem is that the ecu has a cam sensor code. I was told that the Ls7 has 4 lobes on the cam and the lq4 is only looking for 2 lobes, is there some fix to this problem so that i dont have hard starts and a check engine light ??
No cam sensor locations are completely different... LS2/LS7 have the cam sensor up front and ls1/lq4 have the cam sensor in the back. Gen 3 vs Gen 4.... So obviously the reluctor on the ls7 cam is on the front vs the ls1 cam reluctor on the back.
Pull the front cover, swap the cam gear, install the new front cover and cam pos sensor, click on the harness, and you're in business.
PS: talk w/ them about it before you drop your cash. Not sure if the cam sprocket is a 3-bolt or 1-bolt piece and you'll want to ensure you get the right one...
