As said the crank position sensor is a hall effect sensor. The feed is 8volts from the PCM, If your reading 7.4v thats okay as it also is feeding the cam sensor and there will be a voltage drop when reading this. The signal coming from the crank sensor to the PCM is a square wave 0-5 volts. 5 volts when there is no metal in front of the sensor head and 0 volts when the tooth passes in front of the head. So if you back pin the sensor (put meter between ground and signal out)and crank the engine you should see the pulses (0-5 volts). It does take a while to set the code 11. A lot of cranking with no signal. You might have set this code if you tried cranking the engine with the sensor disconnected. Either way, back pin the sensor, crank the engine and see if you get the pulses (0-5volts)
