There is only one crank sensor fitted, you may also have a cam sensor. the crank sensor is located either around the bellhousing or around the front crank pulley. It either has 2 or 3 wires. It picks the signal off the revolving crank so look for a sensor in the block near flywheel.
There is a tone wheel on the crank/flywheel that the sensor reads off of, if that is your question.
fuel pump or crank sensor
No, The pcm has to see a signal from the sensor
It's on the back of the engine....and hell to get to. Better off taking to a garage. I just broke mine off. Now I have to drop the oil pan and drive it back out.
On a 4.0 V-6 the crank position sensor is in a fixed location and cannot come in contact with the crank if it is installed correctly.
there is a bolt off to the right off the sensor take it out and it should just pull right out.
Yes it can.
Bore the block .040" oversize and put in a 4" stroke crank.
IS this a 5.2, if so the crank sensor is on the passenger side of the engine, in the far rear, it picks up off the flywheel, the cam sensor is located inside the distributor (it is the pick up coil).
They way you can tell if the Crank sensor is bad, is when you run the car for a while and then turn it off, and when you go to start it back up, it won't start,then it's your crank sensor, it's probably cracked, so when it heats up it expands and doesn't make contact. but if you let the car cool off, it will go back together and start up, A faulty crank sensor should trigger a check engine light.
as the crank spins around there is a magnet on it, and the sensor pics up a signal off of it to detect that the crank is in motion. If the sensor fails it will not send a signal to the computor, and that will cause the ignition system to shut down, so you will not have spark.
