Hi guys,

I’m in the midst of finalising my wiring harness design and am confused about how to connect the CAM sensors to make sure I can use the VVTi functionality.

The 3UZ has a camshaft position sensor and two VVT sensors, one on each bank.

the ECUMaster has two Camsync inputs. So effectively I have three sensors relating to the camshaft and two inputs. Which should I be using?


I would think you would use the two cam position sensors, but you should ask ECU Master for help.

Thanks David.

ECUMaster came back and confirmed that only the two VVT position sensors are needed and that the camshaft position sensor at the front of Cylinder one isn't needed.
