5 volts is normal. all the sensors operate between 0-5 volts. The crank position trigger uses a 5v or 0v signal- as the windows on the flexplate/flywheel pass under the sensor, the voltage goes from 5 to 0 telling the computer that a piston is at TDC. others, like the MAP, TPS, etc. use a varying voltage to articulate a range of values.

.13 ohms in a wire sounds normal. copper wire has resistance and will show some value of resistance on an Ohm test.
