Hello and welcome to JustAnswer!

The problem could be the sensors themselves but it's unlikely that two sensors would fail at exactly the same time, unless there was physical damage during the work that was done.

It's more likely that you have a wiring issue. If both sensors have lost their reference voltage or sensor ground due to wiring damage that would explain neither of them producing a signal. You may have accidentally pinched a wire and shorted it to ground, or a wire may have been pinched or stretched to the point of breaking, or you may have just disturbed a wire that already had an underlying issue. The next thing I would recommend is testing the reference voltage and sensor ground to the cam and crank sensors.
