Any chance the cam sensor wiring harness was damaged when you did the timing belt job? In any case, I suggest first doing a continuity test of those wires, from the cam sensor connector to the ECM connector. If the continuity is good, then check for ground and reference at the connector, and back probe (or use a wire-piercing adapter) on the signal wire. (all you'll get from that is a fairly steady voltage or frequency). If all of that tests ok, then you could do a complete test of the signal by taking it to a shop having a scope, instead of buying one.

EDIT: After posting, I realized that I was thinking of the crank sensor, and that the cam sensor is different. So, all you need to do is test the pink wire at #1 for power, the black wire at #2 for ground, and then the remainder of what I wrote above applies to the signal wire at #3.
