Been troubleshooting a G40 Camshaft Position Sensor No Signal fault code. Wondering if just plugging in a brand new sensor as a quick test will make the fault code go away or does the CPS need to be completely installed and in place for the fault code to go away.

Yes, it would have to be installed properly. It's a hall -effect type sensor according to the PDF that was linked here just yesterday. The ears on the cam sprocket is what triggers the signal.

First, make sure you aren't out of range. The cam positioner will go '0', no read if that is the case. Also, BEW's are notorious for losing the ground from the cam position sensor to the ECU. It's the brown wire.
