Very doubtful. First of all, forget the sensors. Computers do not send signals to them. The computers may provide the supply voltage to run the sensors, but then the sensors provide data to the computers. There are only a few sensors that can prevent a cranking engine from running. The rest just have a small effect on engine performance. With reversed polarity, no computer is going to turn on, so most sensors won't get their computer-supplied voltage.
While it is possible for a computer to be damaged from reverse polarity, remember there's a diode in them to force the fuse to blow. Most of the time the fuse blows before any further damage can occur, but those diodes are very small and can't handle much current. It is possible for one to short from the excessive current, then actually crack open from the heat. At that point it is no longer in the circuit. Reverse polarity for a second time, or for an extended amount of time, can damage the computer's circuitry and fail to blow the fuse. The point is, it's impossible to know without taking the computer apart to assess the damage.
You need to connect a scanner to view live data. That will let you see what the Engine Computer is seeing from the sensors, and will help you identify if a required signal is missing.
Sorry for butting in Steve. Don't know why I didn't see your replies before I started typing.
